How do you replace sparkplugs on Buick rendezvous?

Answer 1

After successfully removing the engine cover, remove the 10mm bolt that holds down the ignition coil remove it (continue this for all 6 cylinders as this engine is COP or Coil on Plug) , then using a blow gun or air gun blow any debris from inside the spark plug tube, using a 5/8" spark plug socket and a 4=6" extension remove the spark plugs. Be sure to check the gap on your new plugs (.044) then re-install the plugs, ignition coils, 10mm hold down bolts, and then the engine cover. Good Luck!

This is "BBAASPENCER" here in TN and I would like to give you another answer. Actually, the correct way GM list in their service manual is to take off the engine dog bones, attach a pulling strap to the engine and hoist and roll it until you gain access. That is the same procedure for many SUV/Van GM front wheel drives. If the first procedure listed here works for you, I'm okay with that. I just wanted to give you another option. Here is a video on this new engine tool. Will try it soon to see of it works. http://www.YouTube.com/watch?v=tlIkbbl7cBo
