How to buy good quality cooling fan/radiator motor
Fans are necessary to prevent overheating of the components under the hood of the car. Excessive heat can cause warping, melting, and other damage, not to mention additional power consumption. The radiator is one of the hottest parts in the engine bay as its sole purpose is to circulate hot coolant and dissipate heat to send the cooled coolant back to the engine.
In the past, all cooling fans were mechanically driven, meaning they were powered by a motor. The problem with this type of fan is that if the motor is running at low speed, then so is the fan. And the power needed to keep the fan running means that power and performance is being diverted from the motor.
Electric radiator fans change all that. They are powered by their own engine, so they can keep cooling no matter how fast (or slow) the engine runs. But like most components in your car, these fan motors can burn out and require replacement. You want to find a reputable brand with a reputation for durable parts because the fan motor will be used a lot.
How to make sure you get a good quality radiator fan motor:
Select a puller type if the fan is the only source of cooling for the heatsink. Pullers are installed behind the radiator and remove air from the engine. The pushrods are good auxiliary fans and are mounted in front of the radiator, pushing the air away.
Select the correct CFM (cubic feet per minute) rating: in general, a 4-cylinder engine should have at least 1250 cfm, a 6-cylinder engine should have 2000 cfm, and an 8-cylinder engine should have 2500 cfm .
Make sure the fan on the motor has at least four blades. The more blades, the more efficient the cooling.
Check the warranty. Many manufacturers offer at least one year warranty on radiator fan motors.
