Tune-Up

On newer cars a tune-up generally includes changing spark plugs, checking the timing, and changing the air and fuel filter. It is also important to inspect the spark plug wires and change them as appropriate. At a tune up, ask your mechanic to do the above tasks as well as check all fluid levels and to evaluate the condition of the belts, hoses, shocks, wiper blades, tires, battery, and all lights.
