07 H3 with 190,000 miles. Replaced the radiator at 94,000. Now one of the transmission line quick connects at the radiator is leaking just enough to be annoying. It doesn't leak when running, but pushes a couple drops out on startup. if I push the line in towards the radiator while running, it starts leaking. When I pull out on it, the leak stops. Is there an o-ring or seal in the quick connect that needs to be replaced? Any advice on how to stop the leak?

Thanks,
Mark

 

if it is any part of the radiator thats damaged then you either need to replace the radiator or eliminate the trans cooler from the radiator and add an external transmission cooler.

 

Check the orientation of the quick connect clip, if they are in wrong, only one side of the clip is holding the line in place = leak.

When I replaced my radiator recently, the first clip went in easily, I fought the second one for at least 20 minutes. They have to be lined up in the correct orientation, and it's not perfectly obvious which way that is, until it actually clicks into place.

 

Hmm. That's definitely a possibility. I'll check the clips to make sure they're in there correctly and let you know what I find. Thanks for the help!
