How to Choose a Certified Diesel Mechanic

Certified diesel mechanics are essential to anyone who owns a diesel car or truck and businesses that own heavy-duty vehicles and equipment. A certified mechanic can help diagnose problems before they cause major damage and reduce the need for expensive replacement parts. Here are some tips to help you choose a diesel mechanic.

1. Don’t Automatically Choose a Mechanic Based on Price

A mechanic who charges the least might not be the best choice. While they may look attractive at first, remember that mechanics need to make a living too, and their rates reflect the time and effort they put into service jobs. A top-notch mechanic may charge a little more, but you can expect them to have the experience and tools necessary to do the job properly. They also know how important it is to keep costs as low as possible.

2. Consider Your Mechanic’s Reputation

Choose mechanics you trust. Trustworthy mechanics should be knowledgeable, courteous, and committed to creating a positive experience for their customers. They also should provide the service history on cars they repair for resale purposes. A certified diesel mechanic will offer basic warranty coverage to ensure you are protected in case of future repairs.

3. Consider the Mechanic’s Experience, Certifications, and Education

A certified diesel mechanic should have specific training and certification in diesel car or truck repair. It’s also important to ensure they stay up-to-date on products and innovations in the automotive industry via continuing education courses. Certified diesel mechanics know how to diagnose and fix problems with your engine correctly.

4. Choose a Mechanic with the Right Tools for the Job

Choose mechanics who go beyond simply ‘having tools’ by ensuring they have modern diagnostic equipment that can detect problems most other shops may miss. A mechanic without adequate equipment is less likely to be able to conveniently inspect, repair, and certify your vehicle.

5. Choose a Mechanic Who Is Willing to Explain What They Are Doing and Why

Even if you are not a diesel mechanic yourself, it is important to understand the basic procedures your mechanic uses. Ask questions and get explanations from your mechanic. Please don’t go with a mechanic who claims you can’t learn anything about what they do or doesn’t give you the tools to make an informed decision.

According to USDOE, diesel is more popular among medium and heavy trucks than passenger cars. For example, in the United States in 2013, 72% of trucks with a gross vehicle weight rating of 10,001 pounds plus were diesel-powered (a 3% increase from 2009). This means that there is an increased demand for certified diesel mechanics.

By choosing a certified diesel mechanic, you are helping to ensure that your vehicle is properly maintained and repaired by someone with the experience and expertise needed to do the job right.

What You Need to Know About CNG Engine Maintenance

Different vehicles operate on different types of fuel. Nonetheless, the use of diesel-fueled cars has been seen to be embraced by many compared to gasoline. According to the California Energy Commission, diesel has turned out to be the fuel of choice because it can be used by heavy-duty vehicles since it has an extended engine life. Moreover, compared to gasoline, diesel contains more energy per gallon of up to 12%. However, despite all this, more and more people are now transitioning to using compressed natural gas (CNG) with their engines. It has proven to have running costs compared to any other type of fuel. This is why we will talk about CNG engine maintenance for those who are using it or are planning to use it in the future.


When you think about engine maintenance, it usually brings to mind oil changes and tire rotations. However, compressed natural gas (CNG) engines come with their unique challenges requiring regular attention. The good news is that by following a few simple guidelines, you can ensure your CNG vehicle runs like the day you bought it for many years to come.


Have Your Cylinder Pressure Tested At Least Once Per Year


All cylinders should be carefully inspected annually regardless of use. However, they are essential if your car is used as a daily commuter because the elapsed time between inspections will be much shorter. That’s why CNG engine vehicles are built with two-way communication systems between the engine control unit (ECU) and the cylinder pressure sensors. This way, if there is a problem with the CNG cylinder, it will be detected immediately, and appropriate action can be taken before any major issues arise.


Cylinder Rust Removal


It may seem odd that rust could cause natural gas tank problems, but it’s not out of the question. As water accumulates inside gas tanks from condensation or exposure to humid environments, corrosion may form on metal components, including the cylinder walls and valve stems. This accumulation of rust can lead to a host of issues, including compromised welds, cylinder leaks, and even tank ruptures.


Look Out For Damage


When it comes to damage caused by accidents or environmental exposure, it is a good idea to have a professional inspect your CNG vehicle. For example, suppose you were in a collision, and the frame of your car sustained structural damage during the wreck. In that case, there is potential for this compromised section of your vehicle to puncture one or more cylinders upon impact, which would understandably put your safety at risk as well as require the replacement of multiple components.


Watch Out For Leaks


Unfortunately, not all gas leaks are easily seen with the naked eye. Leaks have a way of sneaking up on you, especially those which go unnoticed for long periods. When your CNG vehicle is being refueled or filled from a pressurized nitrogen canister, you will likely hear an audible hissing noise from the pressure vent on the side of your car. This vent helps relieve excess pressure from the tank to maintain safe levels for transport and is not considered a leak. But any time you notice this noise while your car is parked or idling, there could be a severe problem with one of your CNG cylinders which require immediate attention.


Follow these simple steps for optimal CNG engine care throughout your vehicle’s life cycle. Have a professional inspect your gas tank annually to ensure that it is in good working order. In addition, look out for odd sounds while refueling your car (which may indicate potential problems), and avoid parking over unstable surfaces, which could lead to leaks caused by ground shifts or erosion.

Diesel Transmissions: Keep an Eye Out for These Symptoms

A diesel vehicle is often a significant investment, as their fuel contains between 10-15% more energy and can go around 20-35% further on a tank of diesel than a gasoline vehicle (per the EPA). However, they also have problems, such as issues with diesel transmissions that may make your car run roughly. Here are a few symptoms to watch out for when running your high-quality diesel vehicle.

Difficulty Shifting

Most diesel vehicles have a manual transmission, making them quite fun and sometimes even challenging to drive. They should shift quite smoothly once you get the hang of it, though. However, if you struggle to shift (particularly in trickier areas), you probably have a problem with your transmission. Slipping gears almost always indicates a significant problem with your transmission.

Bizarre Noises

Your diesel vehicle will make plenty of noises as it drives. That’s nothing too unusual. However, you might notice some unpleasant transmission noises that can be a pretty big sign of issues as you ride. For example, humming, clunking, and whining noises usually indicate a myriad of problems. Usually, they show problems with the fluid pump that may cause diesel transmissions to fail on you.

Unappealing Smells

When you shift your vehicle and drive for a long time, do you notice a rather unpleasant, burning smell? That may be your transmission fluid overheating and breaking down on you. This problem usually occurs if your fluid is old, and you don’t change it regularly enough. Replacing it may help here, though you may have already done too much damage to your transmission and need repairs.

Shaking or Vibrating Sensations

Does your diesel shake or vibrate when you try to change gears? There could be a few things wrong here. The most likely problem is your transmission, as it may cause diesel to run poorly. However, you may also have issues with your suspension. The easiest way to tell is to gauge when the shaking begins. If it occurs when changing gears (and not while otherwise driving), it’s your transmission.

If you experience any of these symptoms with your diesel transmissions, it is essential to talk to a mechanic or repair shop right away to minimize any dangers. These professionals will work with you to help you understand what is happening. Then, if necessary, they’ll replace your transmission and provide you with a stronger and more secure vehicle. Doing so will help to ensure you get the best results possible.
