There is no need to change you existing radiator when going to an electric fan if all is OK with you radiator. By going to an electric fan you will get better air flow (and better cooling) and free up a few HP from not driving it off the engine. Be sure your electrical system is in good shape too. If your driving a lot of aux electrical equipment like amps, stero etc you may want to upgrade your alternator if you haven't already. This is a common upgrade if you have a fox mustang.

It is best run through a relay and set the temp. That's what's so nice about the proform unit it's pretty complete. You may need to buy a circuit breaker (about $2) to install in line. the instructions that come with it are pretty clear. By having a thermostat you can set where you want the fan to come on at. Normallly you want it a something above your engind thermostat. Your engine thermostat set the low temp limit for the engine and the fas sets the hight temp limit. For example: I run a 185 degree engine thermostat and have the fan come on at about 195-200 degrees. Be sure not to set the fan thermostat too low or the fan will be running all the time. If you have a/c on your car the fan WILL run all the time the A/C is on.
