I'm replacing the radiator on my 2002 astro and looking for the torque specs for the fittings that go into the radiator. I bought a nissens replacement radiator from rock auto and it came with an adapter to fit the trans lines which i immediately stripped out when installing it. the adapter was threading in easy (not cross threaded) and i used teflon tape on the threads. I watched a video on replacing it and he said 33 ft lbs torque.. is that to much? did i kill a $150 radiator?

thanks

33 sounds like a lot. Oil drain plugs aren't torqued that much.

Also... use a sealing paste instead of Teflon tape.

Option 1 - buy another radiator. Install fitting with permatex sealing paste until snug.

Option 2 - if you are able to fix this you would not have stripped out an aluminum fitting so see Option 1 馃檭

Definitely sounds high to me. Though I don't think I have ever torqued one :) Maybe you can tap it for a slightly larger size and use a barbed adapter.

yeah i think i killed it, saw the torque on a youtube video and just went with it, i just read torque guidelines for fittings to aluminum an its way less. Live and learn, expensive lesson

FOR DECADES I'VE ALWAYS DONE THEM BY FEEL... ALWAYS.
They don't really need to be too tight.. just snug.
I also use Teflon tape.. it's never failed me.

if you did strip them, just delete them.
Many say they are not needed.
