I need to replace the Oil Cooler Line on my blazer. I have also noticed another hose on the top left of my radio that looks like it needs to be replaced (noticed radiator fluid starting to leak).


What hose is this? Is this the oil cooler line hose or a separate one?

 

Tranny cooler lines.

 

That would be the transmission cooler inlet line (feeds the cooler).

 

What the first two guys said, after replacing my radiator I can tell you that is the transmission cooler line!
