How come I cant find heat exchanger fans as found on the Ford Mustang GT500? Since the Heat exchanger sit in front of the radiator, I figure you could strap a fan or two to the front of it. Is something wrong with that idea?

As soon as you are moving the fans do next to nothing. In fact they probably add restriction. If you are wanting to cool when stationary try forcing the main rad fan on. Much larger and will cool the whole cooling pack.

okay, thank you! Do I change thermostat or do I need the fan programmed?

Drop in a katech 174 degree thermostat and have your fans come on earlier and faster . What tuner do they give u to upload the tune ?

I changed the fans to come on sooner using HP tuners. you could add more capacity to your HX system by adding a bigger HX tank or get a better HX pump to move the coolant quicker through the entire system.

The Radiator Fan is the heat exchanger fan too. Tune the car to have them come on earlier. It definitely helps.
