How Do You Change The Spark Plugs On A 2004 Chevrolet Cavalier?
Properly gapped spark plugs help ensure smooth engine operation and fuel efficiency. The 2004 Chevrolet Cavalier Owner’s Manual suggests changing spark plugs every 100,000 miles. They also should be one of the parts checked when gas mileage starts to drop. Remove the negative battery cable to prevent electrical power to the engine. If the engine is a 2.2 liter, you will see the spark plug cables and can gently twist them to free them from the plugs. If the engine is a 2.4 liter, unplug the coil connector and remove the four retaining bolts, and remove the coil from the engine. The spark plug cables will be visible; gently twist them to free them from the plugs. Clean the spark plug well to keep any debris from falling into the cylinder when the plugs are removed. Canned air works well, but if it is not available, a brush or other cleaning equipment may be used. Use a spark plug socket with the rubber insert to remove the plug. Inspect the spark plug boot and wire for breaks or tears. R
