Maintaining Your Diesel Engine

There are many reasons why you love your diesel vehicle, including better fuel economy, lower emissions and cheaper and less frequent maintenance checks than petrol vehicles.

But just because these maintenance checks are less frequent, That doesn't mean you can't take care of your diesel engine in the meantime. If you want your beloved diesel truck or sedan to run longer, check out these diesel engine maintenance tips.


As diesel engines tend to last longer than their petrol engine counterparts, they can benefit from more frequent cleaning. Eventually, as a vehicle travels longer distances and performs more demanding tasks, dirt and dust will have more opportunities to accumulate in your engine.

When dirt accumulates in your engine components, it shortens its useful life and can even reduce fuel consumption. efficiency. If you live in an area with harsh winters, exposure to road salt can wear out your engine parts and components faster, increasing rust and corrosion.

It goes without saying that proper cleaning is one reason simple but important way to take care of your diesel engine.

You should consult your owner's manual before you start cleaning. But you will most likely need:

Always make sure that your engine is cool in front of you Start scrubbing and wear protective equipment such as goggles and gloves.


Check your air filter while under the hood. On most vehicles, including diesels, the air filter is located under the hood in a rectangular cold air plenum near the front of the engine compartment.

A dirty filter can "flood" the engine, forcing it to use more fuel to consume to get the performance and acceleration you need.

In general, you should replace your air filter every 12,000 miles, or have it serviced if you notice poor engine performance, poor acceleration, or increased engine wear.


A car's radiator keeps it cool by releasing heat from the engine into the air. But how does this cooling process work?

First, the antifreeze (or coolant) travels through the engine and "absorbs" heat. The hot coolant returns to the radiator, which releases the heat into the air. The freshly cooled antifreeze is then fed back into the engine, repeating this cycle.

Because diesel engines tend to run hotter than petrol engines, their radiators are exposed to higher temperatures, which can lead to overheating. Overheating can deform engine components such as cylinders and gaskets, ultimately leading to complete (and potentially irreparable) failure of the
