Radiator fan motors, which are sometimes called cooling fan motors, generate power for one or more
fans. These work in conjunction with the radiator in your vehicle and the coolant it uses to disperse heat
and maintain normal engine operating temperatures.
The radiator itself is designed with loops of tubing and fins that
serve as a heat sink. Each side of these fins and tubes takes on the temperature of the surrounding air.
This is where the radiator fan assembly in your vehicle comes into play. It forces air through or
pulls air from the radiator core, all the while affecting the overall temperature of the core. The more
cell wall metal exposed to this in-rush or out-rush of forced air, the greater the cooling capacity of the
In vehicles like yours, you'll find an electric radiator fan. It used be that these parts were
powered by the engine's crank, a pulley and a belt instead of a
motor and wires. The advantage of your more modern equipment is that it will shut off when continued
running becomes redundant. This happens when you reach a certain speed and an increased natural air flow
that is enough to keep your engine cool without mechanical assistance.
Like all components in your cooling system, you can tell if your radiator
fan motor isn't working properly because your vehicle will overheat. Other than having a mechanic
diagnose a suspicious check engine light, you can test the wires of the motor and check your fuses to be
sure the motor is, in fact, the failed part. If this is the case, you'll have to shop for a replacement.
If the fan assembly is the problem, you can buy an electric radiator fan kit. The important numbers
to consider are its dimensions and how many cubic feet of air per minute (CFM) it can move. Check your
owner's manual for this information, and then stop in your local store or visit us online to make sure we
have the right part for your car.
