Last time I checked spark plugs are easily seen for that car. They are located on the engine. You will need a ratchet, a few extensions, a swivel socket, a spark plug socket, and a spark plug gapper. As far as how long, I am assuming it's a six cylinder, figure a half hour for a master certified technician, three hours for a shade tree.How do I change the spark plugs on a 2005 chevy malibu?
We need to know the engine size. But usually they're at the middle of the engine for an in-line 4 and on the outskirts on a V-6. You might have to remove coil packs.
