How do you remove the 3 back spark plugs for a 1999 Plymouth grand voyager se?

Answer 1

If you are talking about the 3.3 engine, then you have your work cut out for you.

If you have a vehicle lift, it is possible to reach up through a small open area between the body, engine and exhaust system. It is very tight and you can't really see much, so you have to do everything by feel. A lot of work has to be done with only one hand. It is not an easy job.

Otherwise you need to remove the entire wiper motor tray and the air intake plenum.

You will need to buy a few gaskets to replace the plenum and a couple other components. You can get all the gaskets you need from your local auto parts store in most cases. There is a gasket kit that comes with most of them. You will also want a part cleaner (spray brake cleaner works good) to clean away dirt, oil, grease and other gunk. Washing the engine would also help.

You may want to buy colored tape to mark the wires you need to disconnect. Most are easy to figure out where they have to go back to, but marking them makes it quicker and easier.

You will need a good socket set with several sizes of extensions. Most bolts are Metric, so make sure you have a Metric set too. A regular flat screwdriver and a Phillips #2 screwdriver will be needed. I don't recall needing any special tools except maybe a good gasket scrapper to remove the old gaskets.

Get a bunch of rags.

Make sure you have a good hand cleaner.

Plan at least 4 hours to do the job. This is so you can take your time and make sure you get everything back in place correctly.

I suggest you do your spark plug wires at the same time if they have not been changed in a while.

If your valve cover gaskets are seeping, this would also be a good time to change them.

If you have been told your fuel injectors should be changed, then do them now.

Basically, anything that needs to be replaced on the top of the motor should be done.

I include these suggestion because you will have easy access to these areas while changing the plugs from the top. It will save you from having to buy the same gaskets several times and taking the plenum off several times.
