Best way to remove rear 3 spark plugs 2000 buick Lesabre


Most GM fwd v6s' have to be rolled forward to change the rear plugs. Its not as hard as it sounds though. Usually removing the air cleaner box and then taking the bolts out of the two top wish bone mounts allows you to roll the engine forward enough to change those plugs. You'll just need something to hold the engine forward while you change them. Like maybe a friend or a strap. I hope this helps you.

Changing spark plugs


First remove the big plastic cover that covers the motor by taking off the oil fill spout.Then the plastic cover should just lift right off..No you should be able to see all of the front ones and the rear ones are a little tricky..You'll need a 3 to 6in. extension with a swivel next to the 5/8 deep well socket.Taking them out is usually the easy part to which reinstalling is a little more trickier.Make sure the plug socket you are using has the rubber piece inside of it because you don't want to break the plugs..And when putting rear ones in to use an old plug wire end or just the socket and three inch extension to start the threads because you dont want to cross thread them.After you have atleast threaded them in as far as you can get them and they went atleast 3 to 4 revolutions tighten them up and finish the rest in process you be great..Good luck to you and am always here to help you and anymore questions will be glad to help......
