Diesel engines have twice the power of normal gasoline engines but also require more care. Proper and timely maintenance helps avoid serious performance problems and safety issues. Follow the steps below to increase the performance and the life of your car's diesel engine. Let the car's engine warm up for at least 5 to 10 minutes in cold temperatures to decrease the oil density. Slow oil circulation increases pressure on a diesel engine.
Use a good quality diesel oil to prevent engine gelling, and change the coolant every 2 years to avoid undue engine warmup. Fix any leakage from the radiator, water pump or the freeze plugs. After 40,000 miles, replace the coolant from the radiator to clear out any debris.
Change the oil every 3,000 miles. Replace the spark plugs, fuel injector and timing belt of a diesel engine every 60,000 miles. Replace the timing belt earlier if it shows cracks. Take the car to a seasoned mechanic every 6 months or before the start of the summer and winter seasons for a thorough inspection of the diesel engine and its components. Tips & Warnings
- Do not attempt to work on a diesel engine if you do not have experience. Stick to the basic care and maintenance, and contact a mechanic for professional help.
- Turn off the diesel engine and let it cool before inspecting.
- Wear protective gloves when handling hot engine parts.
