I have a leak on the passenger side of my 99XJ. It does not leak all the time though. I had the rad presure tested and there was nothing wrong with it. I've notice it when it was -15/-20 out side when it was warming up (iddleling). It leaks out maybe a cup of fluid then it stops. I'm puzzled...why would it leak if it pressure tested ok?
I don't want to dump sealant stuff in my rad if I don't have to...
I have a buddy who has a 99XJ as well that did the same thing. He does have 3X the milage I have on mine though...
PLEASE HELP...
and thx in advance!
