How do you replace the spark plugs on a 2002 Buick Rendezvous V6?
Obviously, the front three are fairly easy to reach. The rear three are the real problem. The easiest way to do the rear three is to jack the front of the vehicle up, crawl underneath until you can see the back of the engine from the ground, get real comfortable, making sure the engine and exhaust are cooled down, reach your arm up and pull the boots, very carefully…. then replace the spark plugs. You will not be able to see the plugs themselves, but this seems to be the easiest way. (just replaced the head gaskets on my wife’s 02 rend., what a chore!
