Although most automobiles are gas powered, some trucks, vans, and SUVs are available with a diesel engine. Like gas powered engines, you’ll need regular maintenance and the occasional repair. When searching for diesel shops near me, visit Havoline® Xpress Lube of Kernersville.

Diesel Shops Near Me – How To Find A Qualified Technician

Generally, gas and diesel engines share some similarities in servicing. Both require routine oil changes and coolant flushes. However, diesels are more complicated, requiring specialized knowledge.  Hence, it can be challenging to find a reliable diesel mechanic.

To find the best diesel auto repair shop, begin by asking family and friends for recommendations. After compiling a few, check out their online reviews and BBB rating.

Additionally, check for ASE certification for diesel vehicles. This non-profit organization has been testing and certifying automobile mechanics for over 50 years. Having the designation provides tangible proof that technicians have the necessary knowledge to work on diesel engines. Finally, you may want to give the auto shop you choose a trial run to evaluate their performance.

Common Repairs In Diesel Engines

Although diesel engines are durable, they’re not impervious to wear and tear or breakdown. Below are the most common diesel vehicle repairs:

1. Clogged Fuel Injectors

Like gas engines, fuel injectors in diesels can become dirty, and eventually clogged with carbon deposits. However, diesel engines are more susceptible to this because the fuel contains more impurities. Adding a fuel injector cleaner when you fill your tank can keep parts cleaner, reducing manual servicing.

2. Overheating

As coolant deteriorates, it loses its ability to prevent corrosion as well as its capacity to cool the engine. Generally, you need to change coolant more frequently than gas-powered engines due to the heat output of diesels. Typically, manufacturers recommend you change it every 2 years or 30,000.

3. Incorrect Compression Ratio

Diesels rely on heated, compressed air to instantly ignite the fuel. However, worn parts can allow air to escape, drastically affecting performance. To correct the problem, a mechanic needs to replace or repair the affected part. Typically, one of these is the likely culprit:

• Worn piston rings
• Leaky valves
• Damaged head gasket
• Worn timing belt

4. Worn Out Glow Plugs

Some diesel vehicles may have glow plugs. These are electrically heated components that assist in raising the air temperature for fuel ignition. Generally, glow plugs last about 100,000 miles.

5. Fuel Contamination

Although manufacturers distill gasoline and diesel from crude oil, they have different characteristics.  For example, while fuel contamination can occur in both, it’s more of a problem for diesel fuel.

This is due to 2 separate factors, ultra-low sulfur fuel and the hygroscopic nature of diesel. Refineries remove more sulfur from the fuel than in the past to make them more environmentally friendly. Additionally, diesel is more hygroscopic than gas, readily absorbing water from the air. These two characteristics allow microbes to multiply, contaminating the fuel.

Often, fuel contamination will exhibit one or more of these signs:

• Check engine light illuminated
• Fuel filters clogging frequently
• Power loss
• Sputtering at high speeds
• Decrease in fuel efficiency
