FAN CLUTCH AND FAN MOTOR

In the days of V8s with cast-iron blocks and heads, overheating often meant nothing more than pulling over for awhile, letting the heat dissipate, filling the radiator and getting down the road again. Not true with modern vehicles! Aluminum engines and sensitive electronics often mean that only one overheating incident can do serious damage.

The radiator is, of course, at the heart of any car’s cooling system. An old radiator can often be boiled or “rodded out” at a radiator shop to help loosen up and remove corrosion and rust from internal passages. However, if a radiator’s beyond hope, there’s not much to be done except to replace it with an aftermarket unit. We stock aftermarket radiators, paired with electric cooling fans, all of which exceed OEM specs and are ready for drop-in installation.

Like every other part of a vehicle, manufacturers have been searching for ways to cut weight and maximize efficiency with fan blades. We stock a wide range of OEM-style or lightweight fan assemblies, in many styles, from several manufacturers.

Starting in the 80s, manufacturers started to realize that a belt-driven cooling fan didn’t need to run at full speed all the time, and that parasitic drag on an engine could be reduced with a fan that only runs on demand. Fan clutches save power by partly disengaging the fan (with a viscous-drive and thermostat) at lower temperatures, or even normal operating temperature.

If you elect to do away with the fan clutch, it’s still important to keep the fan at an optimal distance from the radiator for proper cooling. We carry fan spacers to go between the pulley and fan itself, available in original mill finish or great-looking anodized colors.

Most newer vehicles have, of course, gone over to electric fans for cooling. Electric fans are available in OEM or performance styles, with sensors that activate the fan at different coolant temperatures.

NOTE: Remember that your heater core is also part of the cooling system! If you notice poor performance from the heater, blowing either hot air or cool air all the time, it could be a sign of cooling system trouble, even if the engine isn’t overheating.
