The 2004 Chevrolet Malibu is a mid-sized sedan with a 2,189cc 2.2-liter, four-cylinder engine that puts out 145 horsepower stock. There are four spark plugs on the engine located on the driver's side in the middle of the engine. The rubber-covered wires on the distributor cap will guide you down to the four spark plugs on the side of the engine. This is a job that will take a basic knowledge of this vehicle and about 35 minutes.

Open the hood and loosen the metal securing belt on the air intake using a screwdriver. Pull the air intake off of the engine. Locate the four spark plugs on the driver's side of the engine.

Remove the rubber-covered wire caps from the tips of each spark plug. Remove the spark plugs from the engine using the ratchet and spark plug socket.

Gap all four new spark plugs using the spark plug gapper set to .032. Insert all four new spark plugs into the engine and tighten them to 13 foot-pounds using a torque wrench.

Replace the air intake onto the engine and tighten the metal securing belt using the screwdriver. Close the hood.
