Cooling Fan Assembly
Also known as the radiator fan, the cooling fan of the vehicle is in charge of reducing the temperature of the engine, which prevents it from overheating. If you have a busted radiator fan in your system, don't expect your vehicle to last that long. Chances are, you're going to experience problems pretty soon. To prevent this from happening, the best thing that you can do is repair the damage immediately. Here's a short guide on everything that you need to know about cooling fans.
Types of Cooling Fans
There are basically two types of cooling fans, and what you have in your car depends on how old your ride is.
Manual cooling fans are most likely to be found on older vehicles. They are mechanically driven fans like clutch and flex models and they work using a pulley system that is operated by another engine component like a crankshaft belt.
An electric cooling fan, on the other hand, doesn't require any belt to work. It just needs a certain amount of horsepower coming from the motor and this makes the engine work harder and decreases the vehicle's gas mileage.
Troubleshooting Cooling Fans
Here are some components that you need to check if you have a malfunctioning radiator fan in your system.
- Electrical wires
- Temperature sensor
- Coolant levels
- Fan clutch
This is applicable to electric cooling fans only. Check your vehicle's manual to trace the fuse that powers up your vehicle's cooling fan to be able to check if it's the source of the problem. You should also check if the wires of the fan are working using a voltmeter. If voltage runs from the relay to the fan, then you probably need to have the fan replaced.
A busted temperature sensor can make the radiator fan malfunction because the former is the one responsible for the latter's function.
Not having enough coolant in your engine can cause your engine to overheat, so make sure there's always enough for your vehicle to go by.
Holding the radiator fan to the engine, a busted fan clutch can cause problems in your vehicle's cooling system. Over time, this component can get rusty, making it vulnerable to damage.
Repairing a Busted Cooling Fan
Here's a general, 3-step guide that will help you fix your radiator fan in no time.
Step 1: Before you begin, ensure that your car is cool. If it is, locate the radiator fan that's located either at the front or back of the radiator and remove the bolts that secure it in place using a ratchet.
Step 2: After removing its mounting hardware, carefully lift the fan until you see its wire connectors. Disconnect these wires to be able to pull the fan out completely.
Step 3: Once the old fan is out, clean the mounting surface before installing the one. Secure the new cooling fan in place, connect it to the wire connectors, and then test it to see if it works.
