Tech Question

Which fan clutch will give me the most cooling, thermo ornon thermo?


A thermal control clutch – identified by the coiled bimetallic spring in thefront of the hub, will do the best job. As temps increase, the thermostatmechanism closes off an orifice in the fluid drive, reducing the slippage,thereby providing fan RPM close to that of a solid hub.
