Sounds like its just a normal radiator, maybe off a different model ie.hatch,liftback . Not sure.
I've just used the one on the car and added a fan on the front off side of the radiator. I will look for the diagram, I know I kept it. As for toyota, I just told them that I bought A/C & I needed a few more bits and pieces ie condensor type, maybe some piping and some nuts & bolts, as he looked in his book I asked if he could copy it so I can check it with what I have. Or they should have a manual for sale. Get back to you soon.
