Leak at Trans Cooler Fitting

Truck is leaking at the fitting on the driver side where it goes into the radiator/cooler. From what I can tell, it is not the line but the brass fitting that the line goes into. The leak appears to be between the brass fitting and the radiator/cooler.

If I remove the line to replace the seal behind the brass fitting, how much ATF should I expect to come out as I replace the seal? Also anyone have the torque spec for this part?

I don't want to be caught without a large enough pan and have the truck bleed all over the driveway while I frantically try to button it back up.

Thanks, Jasonodsky

You should be able to tighten it. I think it is some sort of flare fitting. Make sure you hold the part on the radiator and the B-nut on the line.

It's leaking between "the part on the radiator" and the radiator. The flare nut is fine and in tight with no leak. Anyone have a torque spec on this? I'd hate to strip the radiator threads.

Anybody have an idea how much fluid I should plan on coming out once I disconnect the line from the cooler? I'll be doing it in subzero weather and would like to avoid suprises!

about half a quart, when the motor is shut off there isn't any pressure there, put a drain pan under it to be sure.

Just had a leak from the tranny line on my EX. I replaced the rubber line and only a small amount of tranny fluid came out, a regular oil pan will be more than enough for ya.
As far as the radiator part I am not sure. Good luck!
