Ok guys I’ve got a question for yall.
I have a 99 Jeep Grand Cherokee, with the 4.0. It recently started leaking antifreeze from around the radiator cap.
I have done the following:
Replaced the old cap with a new one
Cleaned all lines in and out of the
overflow jug.
Cleaned the nipple where the
overflow hose attaches to the
radiator cap neck.

I am at a loss here?

 

I wouldn't blame the new cap.
On my XJ I used to notice that if I did not get the cap on just so it would leak out of there.
I blame it on the radiator.
Plastic sides and filler on my radiator.
So I bent the 2 tabs ever so slightly in on the cap.
Been good ever since.

 

hey thanks for the info. I will do that today!
