Should my radiator fans be intake or exhaust?
Generally, you want the case fans in front of the case drawing in air while the fans at the rear blow air out. If your case has vents at the top, they should be placed as exhaust fans because hot air will rise. Side-mounted fans should be used for intake, though they often don’t have air filters.
Where is the electric fan on a radiator?
An electric fan motor connected to a plastic fan blade located directly behind the radiator which is controlled by a coolant temperature sensor. This engine temperature information is utilized by the computer which signals the control relay to send power to the cooling fan.
What to do if your radiator cooling fan fails to turn on?
If the fan motor fails to activate electrically check the cooling fan fuse and relay and replace as needed. Check the main fan blade mounting nut for tightness. Electrical connectors must free from dirt and debris to ensure proper current flow. Allow the engine to warm up to operating temperature until the cooling fan turns on.
What does a reversible fan on a radiator do?
Some auxiliary fans are “reversible”, which means they can spin in either direction to pull or push air from either side of the radiator. With reversible fans, wiring ends are reversed so that red and black wire leads are swapped, and the fan blade is unbolted, flipped over, then bolted in place again.
What kind of fan should I use for my radiator?
A pusher-style fan is best as a secondary cooling source. Whichever you choose, it’s to your advantage to select a fan that covers as much of the radiator core as possible. To do this, taking the length and width measurements of your radiator is vital.
Is it OK to put an electric fan in front of a radiator?
An electric fan mounted in front of the radiator is a pusher, behind the radiator a puller. A front mounted electric fan asm (including shroud and/or guard/brackets) actually impedes air flow over the core. You want it as a puller.
Can a pusher fan push air through a radiator?
Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. When a vehicle is moving, a pusher fan can obstruct airflow due to its positioning in front of the radiator.
Can a belt driven fan keep your Radiator cool?
Some engines come with belt-driven fans, which move more air at higher rpm but take up more space, sap overall horsepower and can accidentally hit the radiator or shroud in some vehicles, while decreasing the life of the water pump in others. They also don’t move a lot of air at idle.
How does a radiator fan work in a car?
The fan should also turn on after switching on the air conditioner. Positioned between the radiator and engine, cooling fans blow cooling air through the car’s radiator to cool down the heated water and coolant mixture that flows through the radiator. The radiator fans blow cooling air through the car’s radiator. Source: Adobe Stock
