My transmission lines are leaking at the radiator on my 07 1500. I bought a new radiator to put in and took forever to find the fittings. When I found some they don’t have a place for o rings. Anyone have any ideas at all to seal them? Any suggestions would be greatly appreciated

 

return it. Buy the correct radiator

 

I bought an all aluminum radiator off eBay. I can’t return it, or I would have a long time ago. I just need my lines to quit leaking.

 

Can you post pictures of the lines & fittings, as well as the point of the leak? That would be more helpful in determining a solution.

 

I will take some when I get home. It’s leaking where the line goes into the connector that screws into the radiator. The flared end goes into the connector and get a silver clip in back side that holds it in place. That’s where it is leaking from.

 

It may not be the correct way to stop the leak but if you are stuck with the radiator and have no other choice you can try something like JB Weld or a silicone sealer to stop the leak.

 

The quick connect fittings can be difficult to seat correctly, and the clips are easily bent.

Try to get a picture of the inside of the radiator fitting - there are o-rings that can occasionally get pushed out of place.
