REAR SPARK PLUG REPLACEMENT

2002 Buick Lesabre

Engine Mechanical problem
2002 Buick Lesabre 6 cyl Front Wheel Drive Automatic 100000 miles

I have replaced the front 3 spark plugs without a hitch, but it appears that I have to drop the engine in order to get to the 3 rear plugs. Is there a way that I can replace the 3 rear plugs by myself? And if so, HOW DO I GET TO THEM?

It's not necessary to drop your engine. You just need the proper tools.

A spark plug socket with a universal hinge would work the best. Then you'll need an extension. But the length will depend on what's obstructing that particular plug. (Each plug may require a different length).

Also, a magnetic spark plug socket will help you keep the spark plug from dropping. And if something against the firewall is in the way, you can remove it, then reinstall it when you're finished.

Wish you luck.
