Hi I got your reply, and didn't find a diagram of a 4 cylinder for the 1994 pontiac sunbird, and we still can't find out where it is at. And the theremostat we've got here is not the right one.
I am still hoping someone comes up with something for me from you guys. Please reply if you can.
There were 2 types of engines that year for that car, and the one in my car was brazilian made, and the other was a normal engine made my gm. I don't know what to do? I don't have any one to help me. Please if u can try to find a solution for me,
