The fan for the a/c is about 1 1/4 shorter than the fan for the radiator. It has the same bolt mounting pattern but the connection wire has four on the a/c fan. Which one is the 12v and the ground for each fan? and is the a/c fan has enough cooling power like the radiator fan? I wanted to get an a/c fan for the radiator fan because my turbo is rubbing on the back of the radiator fan. And cuz' it rubs, radiator is kidda push forward causing it to angle a little bit. It also cheaper to buy this than that aftermarket Flex a fan or something. Anybody tried replacing this before?
