Easy Steps to Clean a Diesel Engine

Easy Steps to Clean a Diesel Engine

Trucks, equipment and machinery that run on diesel fuel will need TLC when it comes to cleaning the engines. As a diesel truck, machine or equipment owner, you know just how important it is to keep the engine looking spotless. If you neglect this simple task, it can take years off the life of your equipment. Then, you’re faced with unnecessary repairs and premature replacement to great expense.

Yes, the old rumor was that you’re not supposed to clean a diesel engine, but we now know this is just plain false.

First, a Word About Degreasers

Many people with diesel engines will apply a degreaser as part of their regular cleaning routine. It’s recommended to use a water-soluble or citrus-based degreaser, but if you’re not in the mood to spend money on fancy products, simply dilute some dish detergent and it will work just as well.

Stay away from organic, all-natural products on the market such as Simple Green, as they could damage high-strength steel, aluminum, and titanium, as well as electrical connections, due to the hydrogen embrittlement phenomenon. In a nutshell, the hydrogen inside the cleaner can make the material brittle over time.

You may also want to stay away from high-alkaline cleaners like Formula 409 or Fantastic.

Cleaning Tips That Can Help

Ready to get cleaning? Here are some easy steps to tackle this task, many of which are the same as for a gasoline engine.

• Manually remove the debris that’s trapped under the hood and in the grill, using a brush.
• In order to loosen up the grease and oil, making the rest of this task much easier, warm up the engine and run it for five to 10 minutes.
• Cover certain engine parts with baggies and secure with rubber bands. During the cleaning process, there are about four under-hood items that you should cover for protection, including the sensors, alternator, power steering and air intake.
• Apply the engine degreaser from the bottom up to avoid drips on your clothing. Let it sit for up to five minutes, or more, if the engine is really caked with dirt.
• Scrub down all tough-to-reach parts, using a long-handled brush.
• Rinse it all off with a gentle stream from your garden hose, rather than a high pressure spray which can cause damage.
• Let the engine dry. You can either allow the heat from the engine to naturally evaporate the water or you can dry it manually to avoid spotting.
