Inline Thermostat

The Hyper Cool packages come with an inline thermostat fitting and a thermostat switch to automatically turn the fan on when the fluid reaches a certain temperature. This is very simple to wire up, running a single from the thermostat switch to a hot ignition lead and another wire to the electric fan. Since the truck had absolutely no problem running cool unless it was towing or off-roading, we simply wired the fan to an on/off switch so we can turn the fan on whenever doing either of these types of driving.
