There are several maintenance projects that go into a complete tune up. Filters are a large part of a car’s performance and, during the tune up, should be tested and replaced. That includes the air, fuel, and oil filters. Another important part of a car tune up is replacing old spark plugs and checking to see if any spark plug wires should be changed.
Also be sure you or your mechanic inspects the distributor cap for damage. Obviously, the cap should be replaced if it is worn. Another fixture that needs to be replaced if it shows signs of cracking, burns, or carbon damage is the rotor. The car battery is a vital piece of equipment that needs to be properly maintained. Check its charge and clean the terminal for the best possible performance and life of the battery.
Don’t forget about the positive crankcase ventilation, or PCV valve as it is commonly called. If it is in any way clogged, it should be replaced as well. In the occurrence that your vehicle has adjustable valves, these should be adjusted and the valve cover gasket inspected.
And, as always, the car’s fluids should be filled to the correct levels. That includes the coolant, water, oil, and fuel levels. It sounds like a lot to cover, but you will be pleased with your car’s performance and fuel efficiency.
An important note for people who own and drive cars made before 1979, there are some additional tune up steps for classic cars. If the car does not have an electronic ignition, then it is necessary to change the points and condenser. If it does have an electronic ignition, then the timing needs to be properly adjusted and set.
Scheduling regular in depth tune ups for your car is an excellent way to prolong the life of the car, avoid costly repairs, and ensure the best gas mileage. With gas prices at an all time high, this simple maintenance regime can save you at the pumps.
