Common diesel engine problems

Failure to keep up with routine servicing. Neglecting oil and filter changes and fluid analysis doesn’t help you take care of your engine.

Overheating. Diesel engines run hotter than gas motors, which means the radiator is subject to higher temperatures. Proper cooling system maintenance is important. Don’t neglect your coolant as it will turn acidic over time, which hurts the engine.

Filthy filters. If you aren’t replacing the diesel filter regularly, it can “choke” your engine. This forces the engine to use more fuel to get power and acceleration and wears the engine down. You’ll know to check your filter when you notice weak acceleration or decreased engine power.

If you have an older diesel engine, be sure to empty the water separator to avoid leaks or moisture residue that can damage the engine. You’ll also want to let the engine reach the proper operating temperature to get efficiency.

With new diesel engines, don’t forget oil additives. Since these engines create a lot of heat and water residue, they can help enhance engine lubrication with fuel additives. In winter, you’ll want to use winterization additives to prevent fuel clogs and reduce efficiency.



Solutions to Common Diesel Engine Problems

All diesel engines are different, and as such when it comes to problems with diesel engines there’s no ‘one size fits all’ solution for any diesel engine problem, whether common or uncommon. It must also be noted that it’s imperative to determine the cause of the diesel problem and address this issue before simply replacing damaged parts and reassembling the engine.
