I have a question. First does anyone know which side is supply/return of the trans cooler lines going to the radiator on a 1998TJ 4.0L with auto trans. I want to install a Hayden oil cooler. I know how to check doing the cold start/fluid test, just trying to save time and effort. I am an old guy with a new Hayden oil cooler # 402 still in the package I bought in 1986 and didn't use. Now I do have a use for it-since I bought a clean used 1998( w/83K mi) Wrangler. Also because of the "V" support rods in front of the a/c condenser-anyone have any mounting ideas. I dont want to mount it at an angle. I guess I could make custom brackets to hold out in front of the condenser,although that would not be as efficient. Thanks for any replies.
