Where are the spark plugs on a 2000 Oldsmobile Alero?

Answer 1

In order to gain access to the spark plugs on a 2000 Alero, you must remove the cover on top of the engine that has the engine size. The cover is like a faux valve cover, once you pull it off, you can easily gain access to the spark plugs. You don't need to take off any cover if it's the 3.4 (3400). Look directly behind the radiator and you will see three wires going to the plugs. The other three are located behind the engine in the same location as the front. Just follow the wires and you'll do fine. On a 2000 Alero with a 2.4L, they are located under the cover from the top of the engine. They can be accessed by removing the four bolts on the top cover, then unplugging the wire connector located on the right side.
