Diesel engine requires timely and a good performance of maintenance, to avoid any trouble and safety issues with your diesel engine. Let your car warm up for 5 to 10 minutes when cold temperature to decrease oil density. Change the oil every 3,000 miles, replace the timely belt earlier if it shows crack. Use a good quality diesel oil to prevent engine, gelling, and change the coolant every 2 years to avoid undue engine warm up. Fix any leakage from the radiator water pump or the freeze plugs. Check the oil transmission fluid level every week. Get a car check up every 50,000 miles. Also clean the air filter every 15,000 miles so it won’t be dust that is keeping the cold air away. Take your car to inspection every 6 months before the seasons start especially summer and winter. These are some ways you can take care of your car.
