1995 Pontiac Bonneville NEED TO KNOW

There is something called a tranmisson cooler lines on that vehicle. But thats for the transmisson not for the power steering fluid, from the sounds of it you need the return power steering hose

What is this cooler you speak of? A metal line, a rubber hose?

Most of the time trans cooler lines are metal to rubber, just look for two lines coming off the transmisson going into either the raidator or it goes into almost looks like a mini raidator on the front of the car in front of the raidator, thats a trans cooler, but like I said some are cooled through the raidator and some have an actaual cooler, what state are you in?
