There are plenty of reasons that people choose a diesel-fueled vehicle over a gasoline-fueled vehicle. Typically, a diesel vehicle gets better fuel economy, has lower emissions, and requires fewer maintenance checks than gas-powered vehicles. A big question that many people ask before purchasing a diesel is how do you maintain a diesel engine?

Whether you drive your diesel vehicle for work or play, to keep it running stronger and longer, plus avoid costly diesel repairs, then check out these maintenance tips:

  1. Keep a Clean Engine. When dirt collects on your diesel 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 can result in rust and corrosion. Your owner’s manual will list some guidelines for cleaning the engine but consult with a diesel service technician about this process.
  2. Check the Air Filter. A dirty filter can “choke” your engine, forcing it to use more fuel to get the power and acceleration that you need. Generally, the air filter should be replaced about every 12,000 miles. Or if you notice decreased engine power, weaker acceleration, or increased engine wear, have the filter checked out regardless of the number of miles.
  3. Take Care of the Radiator. Diesel engines tend to run hotter than gasoline motors so their radiators are subject to higher temperatures and overheating. Overheating may warp engine components, eventually leading to complete engine failure. Regular coolant or radiator exchanges can help prevent overheating. Many diesel engine manufacturers recommend radiator fluid exchanges about every 40,000-60,000 miles, but check your owner’s manual for your specific vehicle. If you notice any of the following signs, have your cooling system checked out as soon as possible:
    1. Orange or green fluid leaks under your car
    2. A sweet smell coming from the engine
    3. Steam coming from under the hood
  4. Replace Fuel Filters. Most diesel engines have two fuel filters—a primary 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, it tends to absorb more water from condensation in the tank. Water particles in diesel can cause a few things to happen:
    • Decrease in horsepower.
    • Engine could stall.
    • Fuel injectors could explode.

    Typically, these fuel filters should be replaced every 10,000-15,000 miles, but again, check your owner’s manual for your make and model. Replace both filters at the same time to maximize their efficiency and lifespan.

Remember: Regular diesel service will help keep your diesel vehicle a reliable source of transportation and prevent costly diesel repairs.
