Spark Plugs on a 1999 grand prix

Hi, I have a 1999 grand prix that i plan on changing the spark plugs. It has a sideways V6 and I can't get to the rear 3 spark plugs very easily. Im still learning and don't know how I am supposed to get to them. Am i supposed to remove the intake manifold? Please help, thanks

No you don't need to remove the intake manifold. You probably need a universal joint on the spark plug socket to be able to get to them. I checked the GM service procedure and there are no special instructions called out. Be sure to clean around the plug before removing and check the gaps of the new plug.

On some of those motors, you can undo the top motor mount and tilt the motor forward. There is even a 2nd hole in the mount to hold it that way while you are changing the plugs.

The universal joint may help make it possible to get the socket on the plug but it want change the fact that it is very tight back there. What puncho said is correct you undo the Two (dog bone) mounts and pull the motor forward. The mounts are very easy you just take off the bolt that goes in the mount on the motor side (I think 13 and 15MM bolt & nut)

After taking the front mount loose(the one at the top of the radiator).Put the car in gear and rock it back and forth until the firewall side of the engine is lifted the highest,then set the e-brake while it is in that position.
I found those direction on another forum and it worked great on the 92 lumina I had to change the plugs on.

Actually, there is a square 1/2 in hole in the mount that you put a Johnson bar in and you can move the engine with that. Takes about a minute for the whole operation.

I did my (now gone) Park Avenue without too many issues, just had to practically lay on top of the engine to get the rear plugs... I have long arms but managed to do it with a 1/2" socket wrench with the normal spark plug socket.

It's more of a 'touch' process
