How to Prolong the Life of the Turbo in Your Diesel Engine

Diesel engines and their parts usually last longer than petrol engines because of their robust design. However, special care needs to be taken to get the maximum useful life that diesel engine parts are capable of. This article discusses some of the measures that you can take to extend the service life of the turbo in your vehicle's diesel engine.

Watch When You Start or Stop the Engine

Avoid starting your diesel engine and driving off immediately, especially on cold mornings. This is because you may need to allow the engine oil to circulate the entire turbo before you drive off. Otherwise, unnecessary wear will take place within the turbo if you don't allow it to be sufficiently lubricated before you drive off. The time that you let the engine to run before you drive off enables the oil to warm up and attain the correct viscosity for proper circulation within all the moving parts of the engine and turbo. Similarly, you should not switch off the engine as soon as you stop after a long journey. Such an action denies the turbo time to cool slowly after it has worked hard during your trip. Let the engine run for a few minutes before you switch it off.

Pay Attention to Oil Changes

Carbon is usually formed as a by-product of the combustion process inside the engine. That carbon is mixed in the engine oil. Over time, the carbon inside the oil begins to block the effectiveness of the oil in the process of absorbing the heat from the turbo in your engine. Consequently, the turbo will wear out quickly due to heat stress. Avoid this problem by changing the engine oil at the recommended intervals.

Install a Water Separator

Some diesel vehicles may come with a water separator installed. That separator is usually located close to the fuel filter. It removes any water that is in the fuel being taken into the engine. Drain that separator frequently so that its contents don't eventually find their way into the engine. The turbo will last longer if its parts aren't exposed to moisture within the fuel entering the engine. Install a water separator in case your mechanic confirms that your vehicle doesn't have it.

Watch Coolant Levels

Avoid putting only water into your diesel engine's cooling system. Water alone may not cool the heated engine parts effectively. It may also cause corrosion within the engine and turbo. Instead, use the correct coolant and water mixture to keep the engine cool. The turbo will last longer once it is protected from overheating and corrosion.

Many causes of turbo failure in diesel engines can be attributed to poor maintenance and driving habits. Implement the suggestions above and you will prolong the durability of your vehicle's turbo.
