Engine Fan Control

AD105 thermal switchAD Thermal Switch

Used in the HMMWV program, the switch provides overtemperature control in the coolant system. A generous 10F-25F differential (hysteresis) allows the fans to cool the system sufficiently and avoids a constant cycling situation where the fans run frequently.
