Used this for a pusher fan on condenser to supply more air flow. Have dual puller fans also, but in Arizona heat a little extra works just fine. Keeps air conditioning head pressure down also helps engine temp to keep it at 190 degrees all day long in any type of traffic. This system is in a 57 Chevy with aluminum down flow radiator works with no problemo!!! Would recommend this fan to any one, you can easily modify to mount it like you want to. Also reverse the two wires and make it a puller fan If needed. Great product, no louder than stock fans in newer vehicles.
