hey iwas taking apart this 87 turbo with auto today i notice that theres 2 extra hose in the radiator... i try to traced where the lines go and it seems that it goes into the auto tranne...

anyways i was thinking of putting this radiator in my 5 speed turbo... but should i use it as an oil cooler?(or will it be to hot) or should i use it for power steering cooler?

or should i just stick with the other radiator that i have?

You already have an oil cooler, I would plumb it up as a power steering cooler. That or just drain and plug it.

I was kind of wondering about doing this also. The OEM replacement rad that I bought has the tranny cooler in it, but I did a 5 spd swap so I don't need it. I thought it would be neat to get rid of the stupid stock PS "cooler" and plumb it into the tranny cooler.

I didn't know if it would actually cool it at all though since it's part of the radiator.

yeah... but it worries me because the possibility that the oil might heat up the temp of water OR visa versa

I would not use it for a oil cooler, if it cracks, you've got water mixing with your oil, and you'll be buying a engine... unless you like to do that.... but using it as a PS cooler, THANK YOU! Im doing that tommrow.....

Well, a powersteering system is like $1500 cheaper then a motor... so pick your risk
