What is with the oil filler cap? This is my second KJ, why are they so hard to unscrew? On my 02' I put some white grease on the threads of the cap, and this helped. Now with my 04' I need to carry around a strap wrench, to get the dam thing off! I even tried swapping my 02' cap onto the 04', and it's still impossible for me to get it loose, by hand. Anybody have this same problem? Anyone found a solution? It's just driving me crazy!

Mine is a pain also
It must just be how they are, maybe some minor grime or something of the like just gets in the threads and causes it to stick
I was having to remove mine earlier actually and was getting a little frustrated with it
It'll eventually come off you just have to have some nice forearms I guess !

All of mine are tight but can remove them by hand

NOW what drives me crazy is when I am asked to do something under the hood of someones and the dang cap is on upside down ! First thing I have to do is put it on right:icon_razz:

The secret is to use a bit of grease on both threads inside & cap threads.
There also is a removal tool!! :gr_grin:

My cap can get a bit stiff too, but I've always been able to remove it. Instead of white grease, maybe try some Kentucky Jelly, it's a non-petroleum lube. The stiff cap is so common, Lisle makes a wrench for it, part #34000. Until the wrench arrives, eat your Wheaties! ;)

I was having such a hard time i keep pliers in my drivers side door. Found a small pair that fit perfect. I used to put some leather gloves on and take it right off but its easier to have a tool for it. Less stress.

I take mine off 20-25 times a day just to build up my hand and arm muscles
Comes in real handy with some of these limp hand shakers we have bred over the last 25 years :gr_grin:

Do schools still offer weight training? Maybe they should add Jeep oil cap turning to the program. If that doesn't turn you into a real man, nothing will.

True that. I used to get frustrated knowing i need oil and struggling to get it off. Easier to use the channel locks. Beats up the cap a little but well worth it.

I have trouble with mine too but I do get it off with a little force. I always oil the threads good and it still is hard to unscrew. A little extra force and a couple of 4 letter words seems to work for me.

I have the Lisle tool and I clean and lube the threads whenever I take it off.

Vaseline is a petroleum product, as is motor oil and conventional grease. If the motor oil swelling the rubber is the suspect, then Vaseline isn't going to be any better. That's why I suggested trying Kentucky (KY) Jelly. It's water soluble, and not petroleum based. I have a tube in the garage (not the only place), you never know when you're going to need to slip something into a squeaky tight spot. :emotions33:
