I bought this fan to replace the factory clutch driven fan in my 1982 Toyota Supra. When I was working on the car, I broke the radiator shroud and my clutch driven fan could no longer create adequate air draw through the radiator to cool it. I bought this unit, along with a mechanical thermostat and it worked flawlessly. It's not heavy duty setup, but it worked perfectly for my application. It kept my car cool on the hottest of days (near 100*F). The install method is relatively simple, you shove plastic screws through the fins on your radiator, then run a plastic nut on the other side. Once again, it's not a real heavy duty setup, but it works perfectly for me. If you are looking for a good replacement/alternative to a mechanical fan and you know this one is adequate to keep your engine cool, I would definitely recommend it. Make sure you buy a thermostat to control it. Also, make sure you have an extra space free on your fuse box so you don't have to wire your thermostat directly to your battery. I had to take this route, because my 82 Toyota didn't have any spare fuse links. The thermostat would kick it off and on for about 10 minutes after the car was shut off on a hot day.
