    A few months ago I bought an 04 GP, 130k miles. Today I noticed that its dripping coolant, I did some research and couldn't find my problem. I circled the area where it seems to be the most wet, but I still can't find the leak.

    I checked a few things already, both plastic elbows seem to be fine, the oil isn't "Milky".IMG_0414.JPG

    thanks for any help.

    It's probably the elbows. Even if they aren't cracked, they might not be sealing and it's dripping out.

    So if the oil isn't milky is there anywhere else it could be leaking? I checked the elbows and they seemed to have some seepage, nothing that looks like it was dripping.

    If you do replace the elbows, get the new Dorman aluminum version. They're much stronger than the plastic ones. I got mine at O'Reilly's for around $12. Rock Auto also has them. I replaced them when I did LIM gaskets and a new upper intake manifold. It fixed my coolant leak.
