The Kit Masters Engine Cooling Fan Clutch controls radiator fan engagement on Caterpillar engine applications, helping the fan work hard only when cooling demand calls for it. This clutch links the fan drive to engine cooling needs, bringing airflow through the radiator during heat buildup and easing fan load once temperatures settle. On trucks that idle, climb, pull weight, or work in hot yards, poor fan clutch response can lead to overheating or wasted engine power. Caterpillar cooling systems depend on clean engagement because airflow has to arrive at the right time. The Kit Masters 91020 keeps fan drive response tied to real engine temperature demand.
