How To Clean a Diesel Truck Engine

Cleaning a diesel engine is similar to cleaning a petrol engine and is not very complex. You can do it at home. Here are the steps you can consider following when cleaning your engine. 

  1. Remove all the debris on the surface of the engine, including those clinging to the grill and the hood. The debris is of varied sizes. Some you can remove by pulling as some you will need to wipe out using a brush.
  2. After removing all the visible debris, turn on your engine and let it warm for 10 minutes. Doing this will melt and loosen the oil on the surface of the engine.
  3. The engine is composed of very delicate parts that water can destroy. Consider protecting components such as the alternator, air intake, sensors, and power steering filler. You can cover them using plastic bags and rubber bands. You can check your owner’s manual if you need to know where these items are.
  4. Spray the degreaser on the surface of the engine, in the grill, and under the hood. For safety, spray it from the bottom, so it does not spill on you. Let the engine relax for five minutes before taking any action.
  5. After five minutes, gently scrub your engine, grill, and hood using a brush with a long handle. When doing this, focus on the areas that hide a lot of dirt and are hard to reach.
  6. When cleaning your engine, never use a low-pressure spray, but use water and gently flow it from the hose. High-pressure spray can make water access the delicate parts of the engine. 
  7. After rinsing your engine, let it dry. You can let the engine heat to dry faster, but for a cleaner and spotless dry, you can use a cotton cloth to dry your engine by hand.

The hydrogen component of household degreasers can interfere with the electrical connection of the engine. It is, therefore, essential to buy products made for engine care.


Dirt accumulation can damage the engine with time. It is, therefore, essential to clean your diesel engine regularly, especially at the end and the beginning of every season.
