Auto Cool II

Auto Cool II was designed for small to mid size engines.

Drives single fans to 40 amps with built in circuit breaker.

The fan rpm varies to control the temperature of your radiator. Install Auto cool under the hood or dash to hide it!

You can set the radiator temperature by the black knob.

This technology lowers the current spike on your alternator over on/off radiator fan controllers the fan can be adjusted to full rpm or down to 50 percent for less noise in the air conditioning mode with an external control pot.

The temperature control will over-ride the air conditioning mode. The sensor is installed on the outflow port of the radiator – under the hose.

Auto cool controllers do not change the engine temperature. Special order a 24 volt Auto Cool II controller for car truck or a military vehicle.

Auto cool controllers are made in southern california!
