Leaking lower transmission coolant line on radiator
 

Hi all, I've recently replaced my optispark and water pump and also the radiator due to a small pin size leak. After getting everything back together my petcock on the new radiator is leaking and also the lower transmission coolant line where it screws into the radiator.
Going to try some plumbers tape on the petcock and see if that will work. Any suggestions for the transmission coolant line connection? It's tightened up as tight as it will go and still leaking. This is a 93 LT1 btw.

Thanks for any help.

gona have to take the line out and see if the flare has been damaged or the pipe has cracks, also make sure the flare is lining up right, not bent and you don't have any crud in there.

Ahh man if it ain't one thing it's another.

You can visit a pneumatics/hydraulic shop and buy a flared copper washer for sealing. Works every time.

Thanks for the suggestions guys. I tried some teflon tape and it worked on both leaks. Just hope it holds. FINALLY able to drive my car again after 3 and a half months working on it off and on. It runs great tho now!
