98 Grand Prix spark plug change?

How do you get the plugs in the back? Its a 3.1. Am I going to have to have a dealer do them?

If you're having trouble getting to them you can unbolt the two "dog-bone" type motor mounts on the front and roll the engine forward. That will give you some room. For what it's worth, that's part of the procedure for putting headers on a W-body (Grand Prix, Regal, Impala) car. You may have to find a way to hold the engine forward. I just rolled the whole car with the tranny in park and the mounts undone. Once the motor was rolled I put the parking brake on and chocked the tires. It stayed put just fine.

That is how you service the rear bank on transverse V6 FWD WB.

Good response.

Are the dog bone mounts the ones attached to the top radiator section? When the motor is rolled forward, does this disturb anything else such as exhaust, wiring or other equipment?
