Just as it says, This is a 16" 5 blade fan from a midsize SUV I believe, real similar to the camaro fans, I mounted it to the face of the radiator with some long bolts through the fins on the radiator and some rubber squares with nuts behind them, but the one side, "sort of the frame" is flush against the radiator does this cause anyone else problems mounting it this way?\ .. Now the problem, I bought a thermal switch from the parts house that screws into the manifold and has two "male" pronges to connect the power leads to, but the parts guy couldn't tell me what the temp of the switch was the book said nothing and we looked at many of them. So assuming surely it was average to have them all come on with in about 10 degrees I bought it and hooked it up to the port in the front of the manifold, DIDN'T WORK got real hot (not in the red)above normal and never came on. So I hooked up a manual switch for now and will order a real thermostat from summit I guess. They also sell a mounting kit that mounts the fan flush against the rad. like I have it. so I assumed it was fairly safe. All experiences welcome OW, /forums/images/graemlins/thumb.gif I like the throttle response and other qualities it brings!!!!!!!!
