Coolant Leak 04' WJ
Well this problem has started happening 3 weeks ago. I now I am leaking coolant because sometimes I can see it dripping from underneath my Jeep. I can say it's not leaking from the Radiator because it's dripping somewhere under the engine. I saw some of it before my Oil Pan. And when I put the Heat on it smells like coolant. So I can't really use the heat for a long time. My Coolant Resevoir went from a little above full to Low in 3 weeks. I checked the hoses and they all seam tight. I went under my Jeep yesterday when the smell started and looked under and didn't see anything dripping. Anyone else have this problem? I might go take to a shop this week or next week.

My guess would be the water pump bearing is about to go and it is leaking from the weep hole at the bottom.

^^^+1 water pump. sometimes you can grab the fan and jiggle it,. it really shouldnt have much play.

Checked that already sorry I forgot to mention it. I'm thinking it's a Freeze Plug or the Heater Core.

Thanks for the Help. :)

Is the front carpet on the passenger side wet? Try pulling it back from the firewall a bit and feeling underneath.

Re: Coolant Leak 04' WJ
It only smells when I have the Heat on. Sometimes when I don't use the heat I can smell it outside of my Jeep. I hope that kind of helps!

Take a good look at the overflow bottle, they can crack as they age. I'd be kind of surprised if it is a freeze plug, as it would be poring out of those.

I will check the overflow bottle again. Thanks Joe!

Well I'm about to get rid of the WJ now. My friends dad told me about a little trick. Get 1 tea spoon of pepper and drop it in the radiator to help stop the leak.
