If you’ve been driving for awhile, you’re probably used to encountering occasional potholes on the road — including some that can be rather large. You know that potholes can create an unpleasant and bumpy ride, but did you know that they may also cause damage to your vehicle? The tips below can help you learn how to handle potholes safely and may even minimize the impact they can have on your car.

What causes potholes?

Many potholes are caused when water seeps into soil under the pavement and then freezes and thaws, weakening the road. This may cause the pavement to crack, which, when combined with the weight of vehicles driving over the road, eventually turns these weak areas into potholes, says the Summit County Engineer in Ohio. Because of the role freezing temperatures can play in pothole formation, severe winter weather can often lead to the creation of potholes.

How can I safely handle them?

If you live in an area with lots of potholes, knowing what you can do to help safely maneuver around them is key. First, you should maintain a safe distance between your vehicle and the car in front of you so it’s easier to spot potholes ahead. You should also use caution when approaching puddles of water as they could really be potholes in hiding. If you can’t avoid hitting a pothole slow down before you hit it and firmly grip the wheel to help avoid losing control of your vehicle.

To potentially minimize the impact that hitting a pothole can have on your car, ensure your tires are inflated to the manufacturer’s recommended level — an under-inflated tire may not have enough resistance to withstand the impact of a pothole. Lastly, you should ensure your car’s suspension is in good condition. It may be a good idea to have a mechanic help you confirm this.

What kind of car damage can potholes cause?

In addition to causing damage to the tire itself, potholes may cause alignment or suspension problems to your vehicle. Below are some signs that your car may have sustained damage after hitting a pothole:

  • One or more deflated tires
  • Severe cracks or bulges in the tires
  • Dents in the wheel rims
  • The vehicle shaking and pulling to the left or right, which could indicate an alignment problem
  • Fluid leaks, which may mean your undercarriage is damaged
  • Odd noises coming from the exhaust system

If you notice any of these issues, you may want to take your car to a repair facility to have a professional check it for damage as soon as possible. If the pothole did cause damage to your vehicle, it may be a good idea to call your insurance agent to see if your auto policy might help cover some of the repair costs.

Some potholes are unavoidable, but learning how to safely handle them on the road may help you save money and frustration down the road. The next time you see a pothole ahead, remember to slow down, and call your mechanic right away if you notice any subsequent issues with your vehicle. It might also be a good idea to notify your city or county transportation authorities so they are aware of potholes that need to be filled.

More drivers hit wild animals during the fall season, according to AAA — and that can mean anything from a mild fender bender to a serious collision. Deer mating season runs from October to early January. Now is a good time for fleet managers to remind drivers how to avoid hitting a deer, and what to do in the event that it does happen.

Experts offer the following advice for avoiding a collision with wildlife crossing:

Slow down: This provides you with a longer reaction time in the event a deer or other wild animal runs in front of your vehicle.

Heed warning signs: Many rural roads feature deer crossing signage. Be on the lookout for signs and be extra vigilant when traversing those roadways.

Be cautious at dawn and dusk: This is when there is high animal movement, but low visibility. Be extra cautious when driving in the early morning or after dark.

Use high beams: When driving at night, make sure to use your high beams, which increase viewing distance of the road ahead. They can help you spot deer in advance.

Pay attention to the side of roads: Deer and other wildlife can suddenly dart into the road, so look off to either side from time to time.

Look for shine: Anything reflective or shiny up ahead could be “eye shine”—that is, a deer looking in your direction.

Eliminate all distractions: As always, set the cell phone, coffee cup and anything else aside and stay focused on the road.

If you are caught off guard and think you are going to strike a deer, experts offer the following advice:

  • Do not swerve: It’s better to strike the deer than to hit a tree or pole.  
  • Brake firmly: But just before you make impact with the animal, take your foot off the brake. This technique reduces the risk of the deer smashing through your windshield.
  • Seek help: After hitting a deer, if possible, leave your vehicle and head to a safe place on foot where you can call for help. If the vehicle is disabled or you are in a remote area, turn on your hazard lights, call the police, and keep your seat belt fastened.

Order-to-delivery (OTD) times for the 2019 model-year fleet vehicles increased, especially for high-volume trucks and vans popular in the commercial fleet market. The top factors contributing to OTD delays were:

  • Strong fleet order volume for trucks and vans, creating a backlog at upfitters and missed ship-thrus. 
  • Reduced availability of railcars and truck carrier shortages.
  • Persistent delays in exporting vehicles assembled in Mexico to the U.S.

“Order-to-delivery times for model-year 2019 increased in comparison to model-year 2018. Across all manufacturers and vehicle lines, we saw average lead times increase by a few weeks. The primary reasons for the increase were: Shipping delays due to rail constraints, plant downtimes, truck driver shortages, plant production capacity strains, early cutoffs, and model-year change overs,” said Jessica Krams, manager, vehicle order management for Wheels Inc. “Orders placed between October and December were especially hard hit by delays. Some orders were even impacted by delays at every point within the order-to-delivery process.” 

This assessment was reiterated by LeasePlan USA. “Things have been crazy all year on the delivery side. It was the perfect storm, with business booming, delays from body manufacturers and chassis delivery,” said Wayne Reynolds, manager, upfit design and consultation for LeasePlan USA.

“Overall we saw a year-over-year increase in OTD cycle times for 2019 among all OEMs and all models purchased,” said Eric Miller, CAFM, director of ordering fulfillment for Element Fleet Management. “OEM-specific shipping issues began earlier and persisted longer than in years past.” 

Equipment constraints with railroads, the primary long-distance transporter of cars and trucks, were a key factor to lengthened OTD times. “Overall, order-to-delivery times increased for the 2019 model-year due to a number of factors, most notably, the ongoing railcar shortage, which also had a trickledown effect in several areas. Further amplifying the impact of the railcar shortage was rail network congestion due to heavy volume. Additionally, large trucks and SUVs remain in high demand, which put additional strain on the already limited railcar interior cargo space. Aside from these challenges on the rails, congestion at vehicle distribution centers and delays in moving vehicles/parts into the U.S. from Mexico also contributed to an increase in OTD times,” said Ted Davis, vice president, North American supply chain for ARI.  

The preceding 2018 model-year was also difficult for OTD, with some fleet management companies, such as Mike Albert Fleet Solutions, reporting that 2019 was not that much different. “OTD times for 2019 felt very similar to 2018. We had issues with a few, very specific vehicles, but otherwise we didn’t experience much change from last year,” said Carly Prather, director of vehicle purchasing and fleet titles for Mike Albert Fleet Solutions

A lesser factor lengthening OTD were quality holds on 2019 models. “With the release of a large number of all-new models, especially half-ton pickups from GM and FCA, delays were unfortunately common to the batch/hold QC procedures from the plants,” said Matt Miller, vehicle status specialist for Donlen. OEM production constraints also played a factor in lengthening OTD times. 

Enterprise Fleet Management observed several other factors that also played a role in lengthening OTD times. “Higher than normal production volumes, challenges with the reliability of vehicle shipments to the U.S. from Mexico, and long dwell times at aftermarket equipment (AME) ship-thru vendors influenced OTD performance during the 2019 model-year,” said Mary Jo Welch, assistant vice president of new vehicle acquisition for Enterprise Fleet Management.

At the core of the issue, there were a variety of factors combined together that increased OTD in MY-2019. Most OTD delays centered around five key areas:

“The top five factors were: Shipping delays due to rail capacity constraints, order volume across all market segments exceeding plant production capacity; delays at upfitters; plant downtimes; and early cut-offs and model-year change overs,” said Krams of Wheels Inc. 

Likewise, LeasePlan USA cited similar key reasons for OTD delays in 2019.

“Some common themes behind OTD delays were chassis shortages resulting in long chassis lead times, along with upfit volume, transportation delays/railcar shortages, and missed ship-thru, where units were shipped straight to a dealer without the upfitting being completed,” said Reynolds of LeasePlan USA.

These were among some of the many findings that were revealed by Automotive Fleet’s 20th annual OTD survey, which is based on data and analyses provided by nine fleet management company (FMC) survey partners that included: ARI, Donlen, Element Fleet Management, Emkay, Enterprise Fleet Management, LeasePlan USA, Merchants Fleet, Mike Albert Fleet Solutions, and Wheels Inc.

The comprehensive OTD survey tracked deliveries of approximately 270,019 new vehicles in the 2019 model-year, representing 110 different models.

The survey methodology calculated OTD times for cars from the day an order was placed with a factory to vehicle delivery to a dealer (not driver pickup). Truck OTD was calculated from order placement to delivery to an upfitter or, if no upfitting was required, to a dealer. The days spent at an upfitter were not included in truck OTD times. 

The New Normal?

The primary vehicle segments susceptible to longer OTD times were full-size pickups, vans, and SUVs.

“Upon review of the OTD data, there seemed to be distinctively different stories to be told. While the domestic manufacturers (GM, Ford, and FCA) with North American production tend to have consistent year-over year to marginally increased OTD timeframes. Full-size pickups, vans, and SUVs seem to be taking the brunt of the longer timeframes. Unfortunately, this seems to be the new normal,” said Miller of Donlen. 

Also, OTD delays tended to increase later in the 2019 model-year. “We saw some challenges toward the end of the 2018 model-year with OTD times for some popular fleet models. Those challenges caused longer than expected delays for some of our clients that ran into early summer of this model-year,” said Welch of Enterprise Fleet Management. 

While there is a myriad factors that contribute to longer OTD, most of the participating FMCs agreed that chassis availability was the biggest contributing factor resulting in the most delays. 

“High-volume demand coupled with lack of chassis availability and rail car shortages have made for a challenging year. Currently I see limited chassis availability as the greatest issue — manufacturers just aren’t keeping up with demand,” said Reynolds of LeasePlan USA.

However, others saw the glass half full and presented a more positive assessment of 2019 OTD. 

“Compared to 2018-MY we have seen improvements in order-to-delivery times for all OEMs. The majority of models were in line with manufacturers’ 2019-MY published guidelines. Overall this had a positive impact in managing our clients’ delivery expectations. Our data has shown improvement ranging from two to 30 days. The decrease in OTD ranged from two to 40 days; however, it was still within OEM guidelines,” said Charles Mathew, fleet operations manager, for Merchants Fleet.  

Other fleet management companies had a similar assessment. “Order-to delivery times were relatively flat for the 2019 model-year. Weather-related delays were non-existent and the railcar shortages that had plagued manufacturers over the last few years were far less noticeable,” said Jim Tangney, VP of vehicle acquisitions for Emkay.

Below are the other key factors that delayed OTD in 2019:

Ongoing Railcar Shortage: Railroads are a key component of the OTD cycle, but are beyond the control of the fleet industry. The ongoing railcar problem seems to have gotten more acute in 2018 and 2019, as have truck transporter issues. “There were widespread rail and truck hauler shortages,” said Miller of Element Fleet Management.

The railcar shortage created backlogs of vehicles needing to be shipped. “The rail industry experienced significant shortages of railcars, causing the rail and convoy transportation network to operate at maximum capacity,” said Welch of Enterprise Fleet Management. 

Agreeing was ARI. “Several factors combined to influence OTD times but generally speaking, overall performance remained steady during the 2019 model-year. The continued impact of the well-documented railcar shortage was certainly the most significant factor and was noticeable across the industry, but most fleet operators were able to plan accordingly for this bottleneck in the supply chain,” said Davis of ARI. 

The railcar shortage was widespread and the top reason for OTD delays. “The industry-wide rail constraints often referred to as an ‘industry-wide railcar shortage,’ hit the OEMs particularly hard this year. As in previous years, truck and van assembly plants saw the greatest delays due to the more complex logistics of getting vehicles to and from upfitters and then back into OEM traffic for shipment by rail,” said Krams of Wheels Inc. “While it’s true that the demand for trucks, SUVs, and vans results in fewer vehicles being moved at one time as they require bi-level or single level railcars, the OEMs are also competing against other industries to move product or natural resources such as crude oil across the country. Auto manufacturers make up less than 5% of all rail traffic; however, they are working with the railroads to increase priority for shipments. Recent rule changes related to switching and routing of rail cars also impacted rail traffic.” 

There was an improvement in railcar toward the tailend of second quarter 2019. 

“Toward the end of 2018, Merchants observed industry-wide railcar delays at various domestic plant locations.  Railcar delays impacted assembly plants in Wentzville, Flint, Arlington, Kansas City, and Ohio. To assist with alleviating backlog, General Motors utilized nontraditional ramps,” said Mathew of Merchants Fleet.  

Despite these difficulties, OEMs were cited as doing an excellent job in helping fleets cope with OTD delays. “GM’s proactive planning and communication to FMCs and clients on model transition on pickup trucks from old to new generation.  Merchants was anticipating OTD delays; however, our data shows overall improvement from 2018-MY by 16 days,” said Mathew of Merchants Fleet.  

There were a number of variables exerting pressure on rail transportation. “Railcar and rail crew shortages, as well as quality holds were the main factors that impacted OTD times. Weather-related issues have not had the major impact that they typically do, though with the hurricane season set to pick up, that could change throughout the remainder of the year,” said Tangney of Emkay.

Production Constraints: The OEMs had a strong demand from both retail and fleet customers, but sometimes struggled to keep up with demand. “As a result, OEM production/capacity constraints occurred on select vehicle models,” said Miller of Element Fleet Management.

In addition, there were constraints on key components from Tier 1 suppliers.

“Production bandwidth (or lack of) for high-demand models such as three-quarter ton and above capacity pickups and full-size vans,” said Miller of Donlen. “There were consistent constraints on popular equipment options. Examples of the constraints include larger 40-gallon fuel tanks on Ford Super Duty models and sliding side door and /or power windows/locks/mirrors group on GM full-size vans.” 

High Customer Demand for SUVs: “All sizes of SUVs still seem to be in high demand and schedulers on the OEM level are consistently challenged with the allocation balancing act of fleet versus retail,” said Miller of Donlen.

Constraints in Exporting Product from Mexico: In general, vehicles built in Mexico have longer ship times. There were persistent difficulties in shipping product from Mexico to the U.S., resulting in delays and uncertainty as to the anticipated delivery date.

“OEMs attempt to mitigate rail delays by utilizing ocean shipment from Mexican ports when possible. This unfortunately compounded outbound and inbound port delays due to the unanticipated higher volumes” said Miller of Donlen.

This assessment was also cited by ARI. “Some domestic manufacturers wrestled with cross-border supply chain disruptions. Often vehicles built or assembled outside of the U.S. faced lengthy delays at the border to reenter the U.S. supply chain,” said Davis. 

Production Errors: “Increased instances of units that had incorrectly assigned final destinations from the factory and / or units missing an upfitter completely and in turn shipping to their final destinations with no fabrication being completed,” said Miller of Donlen.

Ramp Congestion: The delays in rail pickup of finished vehicles resulted in a growing inventory of unshipped vehicles clogging rail ramps. “Ramp embargos were another factor that influenced OTD performance. There was a large backlog of finished vehicle shipments that sat at ramps and yards, causing logistic systems to limit what vehicles were allowed to enter,” said Welch of Enterprise Fleet Management.

Order Volume Exceeding Production Capacity: The strong order volume for trucks and SUVs from both retail and fleet buyers caused factory production to struggle to keep up with demand. 

“The strong retail market impacted OTD cycle times on fleet vehicles,” said Miller of Element Fleet Management.

This was echoed by Wheels. “Both a higher volume of commercial orders as well as retail orders caused lead times to jump significantly on some models over the winter months. As large volumes of orders are placed, this pushes production out farther and increases lead time. The OEMs have been reluctant to add new plants or additional capacity at existing plants since the retail market has been steady the past few years and has recently softened a bit. They may also be concerned about making significant changes ahead of potential tariffs,” said Krams of Wheels Inc. 

Mike Albert Fleet Solutions offered a similar assessment. “There was heavy demand for trucks and vans, which was aggravated by transport-related issues, such as railcar shortages and bayed vehicles. However, there was vehicle availability in pools. Another point that stood out for 2019 is that it seems there was more excessive damage on shipped vehicles than in the past,” said Prather.

Upfitter Delays: The high volume of vehicles scheduled for upfitting and the inconsistency of delivery of units to upfitters created backlogs and delays. 

“The often-unexpected production delays or increases in chassis lead time adversely impacted the upfitters’ ability to start upfits and often disrupted scheduling,” said Krams of Wheels Inc. “Installation times increased due to heavy order volume and, in some cases, installation times doubled. Also, many upfitter parts suppliers increased lead times without advanced warning. Particularly hard hit were body manufacturers producing aluminum service bodies where lead times for just the bodies were in excess of 26 weeks. The lack of a skilled labor pool also contributed to the upfitters’ inability to add shifts.” 

Plant Downtime: This year’s OTD survey revealed that plant downtime did impact some fleet orders. “In addition to the normal holiday plant closures, we saw several plants with down times of three weeks or longer throughout January, February, and March,” said Krams of Wheels Inc. 

Early Cut-Offs Due to Model Year Changeovers: Early order cuts were another factor that impacted fleet ordering and subsequently fleet deliveries. “GM and FCA both transitioned to a new generation of pickup truck models and Ford had an early cut-off on the 2019 Explorer resulting in customers seeking out other alternative models, such as the Chevrolet Traverse, which also experienced an early cut-off,” said Krams of Wheels Inc. 

Dealers Need to be More Fleet-Minded: One weak link cited by fleet managers and their drivers is some courtesy delivery dealers. “There needs to be additional training for fleet-minded courtesy dealers. Dealers constantly indicate they didn’t get an email or mail from Merchants, yet we are able to find original email and tracking information.

OEMs can work on the logistics getting vehicles out of the plants and delivered timely but if the courtesy dealer isn’t motivated to move the car off the lot if we are not calling and following up it doesn’t happen in an acceptable timeframe,” said Mathew.   

Another area of friction with dealers is dealer-installed options for fleet customers. “Proactive communication or increased visibility to courtesy delivering dealers on dealer installed options to ensure the options are installed in the vehicles before they are delivered. Often the options are not installed yet we are billed for them, we find out a few months after the fact when it is too late to go back to the dealership for assistance,” said Mathew of Merchants Fleet.  

Minimal Impact of Quality Holds

Unlike prior model-years, quality holds had less of an impact on 2019 OTD times. “Quality holds played a very minimal role in the overall increase in OTD times this year. We did see quality holds on some models, particularly the Jeep Cherokee and the Toyota RAV4. But overall the delays were minimal,” said Krams of Wheels Inc. 

Agreeing was LeasePlan USA and made a call for greater transparency by OEMs when dealing with quality holds.

“This has been and always will be an occurrence however, the holds we have experienced in the 2019-MY have been minimal and mostly condensed to smaller numbers of vehicles and in some cases one individual vehicle. The bigger issue we face with quality holds is what leads to them in the first place as the OEMs rarely will reveal the reason behind the hold leaving our customers fearing the worst case. Customers want and deserve transparency so they know what to expect and can plan accordingly,” said Rick Smith, director of operations for LeasePlan USA.

A similar assessment was made by Mike Albert Fleet Solutions. “I do not recall experiencing any holds related to new models,” said Prather of Mike Albert Fleet Solutions.

These observations were reinforced by Tangney of Emkay. “We did see some quality holds on new vehicles; however, the resulting delays did not add a large amount of time to delivery timeline,” said Tangney.

Some FMCs report quality holds have already occurred for early 2020 model-year production. “Quality holds appear to have diminished among new model in FY-2019.  That said, we are already experiencing a quality hold for some 2020 models,” said Miller of Element Fleet Management. 

Fewer Weather-Related Delays

Inclement weather in 2019 did result in some weather-related OTD delays.

“Weather continued to impact OTD timeframes for the 2019-MY.  Severe snow accumulation over the winter months and record-breaking rainfall in spring for the central region of the country led to longer durations of widespread delays,” said Miller of Donlen.

Making a similar observation was Welch at Enterprise Fleet Management. “We saw that weather caused delays in select areas of the country over the 2019 model-year. Cold weather had an impact on the transportation system in some states over the winter followed by flooding and hail storms in the spring months,” said Welch.

In addition, weather-related issues impacted deliveries to dealers. “As we have seen in the past couple model-years, weather mainly impacted deliveries from end-destination ramps to delivering dealers. If weather was more severe throughout the year, lead times would have likely been significantly worse,” said Krams of Wheels Inc. 

As with prior model-years, there were several weather-related incidents this year that impacted OTD. “A few of our clients reported serious hail damage that resulted in critical delivery delays. In early spring, significant flooding in the West and Midwest had a severe impact on rail services, intensifying preexisting OTD problems,” said Reynolds of LeasePlan USA. 

Other surveyed FMCs also cited the minimal impact of weather on 2019 deliveries. “Luckily, a relatively mild winter and low hurricane activity helped keep weather-related delays to a minimum. A small number of units in the Midwest were damaged by hail while in transit but the damage was addressed prior to delivery,” said Davis of ARI. 

Making a similar observation was Merchants Fleet. “No significant weather-related delays in 2019 were noted. Flooding in Texas late last year did have impact; however, on average, OTD was minimal due to weather improvement in 2019,” said Mathew of Merchants Fleet.  

Other participating fleet management companies reported that the slow start to the hurricane season had a beneficial effect on vehicle deliveries. “With only two hurricanes to date, Barry and Dorian, weather-related delays have not been as prominent for 2019. However, as of writing this, the storm season is expected to pick up and that may result in some substantial delays due to damage to the South and East coasts. With Dorian new vehicle deliveries to that area of the country were stopped until after the storm has passed,” said Tangney of Emkay. 

Weather typically impacts the delivery process, regardless of model-year, but it was not a significant factor as it has been in the past. 

“Weather-related delays have been minimal for 2019 model-year, though we are headed into hurricane season, which will likely impact this response. We experienced some transportation delays and damage related to hailstorms and flooding throughout the Midwest in the spring ordering season,” said Miller of Element Fleet Management. 

Closing Observations 

All participating fleet management companies cited a need for greater collaborative efforts to identify solutions to rectify OTD deficiencies.

“As we look toward the future, the 2019 model-year further underscored the importance of OEMs, upfit vendors, FMCs, and delivery partners working together to find creative solutions to reduce supply chain complexities and shorten the overall order-to-delivery cycle. It’s clear that fleet operators desire a B2B buying experience that mirrors the ease of a typical ecommerce transaction in their personal life,” said Davis of ARI.

All partners in the supply chain are dependent on the satisfaction of the end-user fleet operator, but this goodwill is being strained in recent model-years.

“We have noticed that clients are becoming less accepting of long shipping times. Therefore, it is important that the automotive industry takes a fresh look at fixing a taxed system and finding ways to reduce OTD times,” said Welch of Enterprise Fleet Management.

There are plenty of reasons you love your diesel-fueled vehicle such as better fuel economy, lower emissions, and cheaper and less frequent required maintenance checks than gas-powered vehicles.

But just because those maintenance checks are less frequent, doesn’t mean you can’t take care of your diesel engine in the meantime. If you want to keep your beloved diesel truck or sedan running newer, longer, then check out these tips on diesel engine maintenance.

1. Clean your engine.

Since diesel engines tend to have a longer lifespan than their gas counterparts, they may benefit from more frequent cleaning. After all, when a vehicle navigates longer distances and more challenging tasks, dirt and dust have more opportunities to collect on its engine.

When dirt collects on your engine’s components, it shortens their lifespan and can even decrease fuel efficiency. Plus, if you live in an area with harsh winters, your engine’s pieces and parts may wear quicker due to contact with road salt, which intensifies rust and corrosion.

Needless to say, proper cleaning is an easy but important way to care for your diesel engine. You’ll want to consult your owner’s manual before you start cleaning. But most likely, you’ll need:

  • An old toothbrush to help you get into the nooks and crannies
  • A moist sponge to wipe down the engine bay
  • A specialized degreaser to safely dissolve gunk

As always, make sure your engine is cool before you start scrubbing, and wear protective gear like goggles and gloves.

Some engine components may not be waterproof, so check your vehicle’s manual to see what’s safe to hose down. Car and Driver recommends using plastic bags to protect those water-sensitive parts while cleaning.

Pro-tip: If you’d rather not use water at all, consider using the low setting on a leaf blower to dust off your engine bay.

2. Check your air filter.

While you’re under the hood, check out your air filter. On most vehicles, including diesel ones, the air filter is under the hood inside a rectangular cold air collector box that’s located up near the front of the engine compartment.

A filthy filter can “choke” your engine, forcing it to use more fuel to get the power and acceleration that you depend on. Generally, you should get your air filter replaced every 12,000 miles, or have it checked out if you notice decreased engine power, weaker acceleration, or increased engine wear.

3. Take care of your engine’s radiator.

A car’s radiator keeps it cool by transferring heat from the engine to the air. But how does this cooling process work? First, antifreeze (or coolant) travels through the engine “picking up” heat. The hot coolant cycles back to the radiator which dissipates heat into the air. Then, the freshly-cooled antifreeze travels back to the engine, repeating this cycle.

Since diesel engines tend to run hotter than gas motors, their radiators are subject to higher temperatures, which can lead to overheating. Overheating may warp engine components such as cylinders and gasket seals, eventually leading to complete (and potentially irreparable) engine failure.

Proper cooling system maintenance such as regular coolant or radiator exchanges are a great way to help prevent overheating in your diesel engine. Here’s what to expect during a radiator exchange service:

  • A specialized cleaning fluid is pumped through the cooling system and radiator.
  • Rust and impurities are eliminated in the antifreeze.
  • The system is topped off with new antifreeze to help it cool efficiently.

Many automobile manufacturers suggest getting radiator fluid exchanges every 40,000 to 60,000 miles, but it’s always best to check the manufacturer’s recommendations for your diesel car or truck. Get your cooling system and radiator checked out earlier if you notice:

  • Orange- or green-ish fluid leaks on the surface under your card
  • A maple syrup-like smell coming from the engine
  • Steam coming from under the hood
4. Get the fuel filters replaced.

Gas vehicles have a single fuel filter, but most diesel engines have two — a primary fuel filter between the gas tank and the engine, and a secondary filter between the transfer pump and fuel injectors. Due to the less-refined nature of diesel, the fuel tends to absorb more water from condensation in the tank leading many manufacturers to build diesel engines with two fuel filters.

When there are water particles in diesel, a few things can happen to your engine:

  • You could notice a decrease in horsepower.
  • Your engine could stall.
  • Your fuel injectors could explode.

Don’t wait for car problems to pop up! Instead, help avoid them with a Complete Vehicle Inspection and preventative maintenance services. Most diesel engines need fuel filter replacement services every 10,000 to 15,000 miles, but you should check the manufacturer’s recommendations for your make and model. Keep in mind that it is advisable to replace primary and secondary fuel filters at the same time to maximize their efficiency and lifespan.

When sitting behind the wheel of a car, there are two things that most drivers want: to reach their destination, and to do so as safely as possible. This means having a car that is in good condition, and that includes its tires. Tires are a part of a car’s foundation. Without them, a vehicle cannot move or otherwise do what it was designed to do. However, not just any tire is sufficient. When getting tires, they must be appropriate for the vehicle type and in good shape to support and transport it.

When buying tires, there are several things to consider prior to making a purchase, such as the type of vehicle, the road and weather conditions they will be used in, and one’s driving style. Popular tire choices include all-season, all-terrain, winter, and performance tires. All-season tires are good for cars and minivans and are suitable for both wet and dry conditions, although they are best for areas that do not regularly go below freezing. Winter tires are designed to handle the cold conditions that are associated with the winter months and can handle freezing temperatures. Both all-season and winter tires are also available as performance tires. The performance version of these tires offers a bit more than the standard versions. For example, performance winter tires have improved grip, while performance all-season tires have a higher speed rating and offer better handling and braking. For people who drive trucks or SUVs, there are also truck versions available that can handle the heavier loads associated with these types of vehicles. All-terrain tires are also ideally suited for SUVs and trucks and are designed with a more rugged tread for both paved roads and mild off-road driving.

Providing one’s car with the right auto care is also crucial. A part of that care is regularly inspecting and maintaining the tires to ensure that they are roadworthy and safe. People can do part of this important maintenance themselves with little more than their observational skills, a penny, and a tire pressure gauge. To start, inspect each tire for cracks, bulges, separation of tread, or anything that may be embedded in the tires. A puncture by a sharp object can cause a slow leak, even if it is still embedded. Look at the tread of the tires to ensure that the depth is adequate enough to provide the proper amount of traction, which is necessary for safe driving. To check wear, take a penny and insert it upside-down into the groove of the tread. When looking at the penny, the top of President Lincoln’s head should not be visible. If it is visible, the tread is low. Tires also have built-in wear bars that will show when the tread is worn down enough to be replaced. If the tread seems to be wearing down on the outer edges of the tire, it could be a sign that the alignment of the car should be checked or that the tires should be rotated. Failure to properly inspect tires can result in a blow-out or hydroplaning or otherwise cause an accident that could result in serious injury to oneself or others.

While performing an auto maintenance check on the vehicle’s tires, one of the most important steps is checking their inflation. Under-inflated tires are problematic in several ways: they reduce a vehicle’s gas mileage, cause additional wear on the tires, and most importantly, they are one of the leading causes of accidents on the road. Because tires lose roughly one pound per square inch of pressure a month, it is crucial that they are checked at least monthly even if they appear well-inflated. To check tire pressure, start by checking the recommended pounds per square inch (PSI) that the manufacturer gives in the car’s manual. If the vehicle manual cannot be located, the necessary information may also be found on a placard or sticker that is inside the door frame of most cars. The ideal time to check the pressure is in the mornings when the tires are cold. If this is not possible and the car has been driven, wait until they cool down, at least a half-hour, as pressure cannot accurately be checked on a hot tire. When ready, remove the valve cap, place it in a safe location, and firmly press the tire gauge to the stem of the valve. If using a digital gauge, a reading will show within a few minutes; with a standard gauge, a small bar will push out to display the results. Compare the information on the gauge to the manufacturer’s recommended amount and add air as necessary. Recheck the pressure after adding air, and replace the cap when done.
