Diesel engines offer superior performance that lasts. However, that doesn't mean these engines don't need routine maintenance to perform at their best. If you are wondering how to take care of a diesel engine or a commercial vehicle in general, you have come to the right place. Check out our diesel engine maintenance checklist below to ensure these essential automotive services are performed.
Keeping Up With Oil Changes
Oil changes are often overlooked, but the truth is that they are invaluable. Fresh oil helps lubricate moving engine parts, absorbs heat, and reduces carbon deposits. For more information on which oil is suitable for your truck's diesel engine and how often you need to change your truck's oil, refer to your owner's manual. You can also check the dipstick every few weeks and charge it when it's running low.
Air Filter Replacement
Air filters tend to work in a similar way whether they are fitted to a petrol or diesel engine. You can usually find them in the cold air manifold. For more information on how often to replace an air filter on a diesel engine, refer to your owner's manual. Once you know the recommended change interval, you can change the filter when the time comes.
Replacing the Fuel Filter
Diesel engines have two fuel filters. The primary filter is located between the fuel tank and the engine, and the secondary filter is located near the engine.You should have no problem changing any of the filters; Simply unscrew the old filter, wet the gasket on the new filter, and then snap the new filter into place. Don't forget to purge air bubbles from the fuel system to ensure a new stream of fuel is moving.
Bleed the fuel system
Air in the fuel system can cause problems, e.g. B. no fuel flow to the combustion chamber. Air can get into the fuel system when you change the filter, so bleeding the fuel system is an important step. To bleed the system you need to open the fuel supply valve and use the manual fuel pump. Run the pump until there are no more bubbles in the fuel.
