I have an 08 jku with 3.8 and noticed coolant leaking under it not a lot that I can actually see it leak only place I see the coolant is around the oil pan gasket and mane some coming down the front of block. Any suggestions or leads would be great if anybody has had this. Thanks

Not sure if this is the cure but I know mine is leaking at the manifold. I don't see any leaking but I can smell it. My father in law is a dealership mechanic and that's what he told me.

I can speak from experience... check the water pump. They can develope a leak at the bottom from the gasket and coolant ends up taking the exact path you stated, ending up around the front edge of the oil pan.

That is what I am assuming the water pump. It is just so tight up in there I cannot see exactly where so just fishing for leads right now. Thanks

Check the water pump. My 07 started leaking around 45K miles. The fluid ran down and along the oil pan. Replaced it myself about a year ago for about $60. No more leak. Seems like a pretty common problem with JKs.

Ya this is kind of a late reply it ended up being the manifold seal. Thanks to extended warranty cost me$150 deductible and didn't have to lift a finger

I've noticed a very simalar coolant leak under my JK & i'm guessing I'm expireicing the same water pump issue as you guys..

I'll keep you guys posted as i locate the exact source of the leak

If the leak is coming from the underside of the water pump; then I would suspect the coolant is coming from the weep hole which indicates the shaft seal is starting to go bad.
Seems really early for a water pump to go bad... at 45K miles....
The '02 GC w/ 4.0L has 170K on original and the '98 XJ w/ 4.0L had 112K when the weep hole started seeping...

I agree. Mine starting to leak at 47 k. Poor quality...

Shoot! I'm at 48K on my 2010 just noticed last week my over flow bucket was empty, so I topped it off Lol

I guess I should go ahead and change it out even though I don't smell antifreeze or see any leaks. Some good PM work before jeep beach


Are all water pumps good to go? Any to stay away from?
