Hi

I own a 1999 Chevy Blazer LT. Because I tow a trailer from time to time, i bought me an aux tranny cooler.

Can anyone tell me which one is the returning transmission line? The upper or lower line on the radiator? (I want the aux cooler in the return line.)

Regards

Thanks for the hint with the + in the search term. That helped me a lot :-)

Is that correct for a 2nd gen Blazer? I know it's the upper line on the transmission side. Is this also the upper line on the radiator side? Can't figure out this on the truck that easy...
