Problem removing my oil cap on my 2002 3.7L engine

I am having a problem removing the oil cap on my 2002 3.7L engine. It is so hard to twist; I need large Channel Lock’s to get it to move even a little. I got a new cap from the dealer, and cleaned the neck of the fill tube, but no joy. Is this normal, that all of a sudden, this cap would stick tight?

Have you tried with it both warm and cold? May help either way. they do make a special wrench for it if you need it. you could try a strap wrench too maybe. Just some ideas.

Same hot and cold. I thought about replacing the neck, but the Air Cond. lines are in the way. I guess the strap wrench may be the way to go. Strange that it would happen all of a sudden.

There is a special filler cap removal tool for a ratchet & Socket.

To assist in removing, coat the threads with a little amount of white lithium grease.

Yea that's the one. I think the rubber seal gets stuck. Make sure you oil it before putting it back on.

Tight Filler Cap!

I had thought about drilling a 1/4" hole, installing a bolt right through the top.
That way all you need is a socket or wrench to get the SOB off easily.:icon_twisted:
