How to slap on a new radiator fan motor
An engine that does combustion is imperiled by overheating, which results to mechanical failure. Likewise, when a car overheats, it will break down and damage some parts of the engine block like the head gasket. Therefore, temperature regulation is critical to the working order of an engine. The main component that regulates the temperature in the engine is the radiator. But what cools down the radiator? This is where the radiator fan comes in. Powered by the fan motor, the radiator fan blows air to the radiator so the coolants within it cool down faster. Coolants with lower temperatures can draw out more heat from the engine. Nonetheless, the fan motor will deteriorate in time and will need replacing. Here's how to slap on a new fan motor.
Required skill level: Intermediate
Needed tools and materials
Uncouple the battery cables
It's important to uncouple the cables from the battery to avoid electrocution.
Unplug the wire connection
The next step is to unplug the wire that powers the radiator fan motor. Some wires are securely connected with a screw so have your screwdriver ready.
Unbolt the radiator assembly
Unbolting the radiator assembly requires a number of wrenches. After this, just pull the assembly out carefully. You might need to move several wires, hoses or even remove other car parts.
Remove the fan blade
The fan motor is the bulge that is directly connected with the fan blade. To get to it, the fan blade must be unscrewed first from the motor. Pull the fan blade out of the drive rod. Check if the fan needs to be replaced also.
Detach the fan motor from the housing
Once the fan blades are out of the way, remove the nuts that hold the motor onto the housing. By then the old, defective motor can be easily taken off.
Install new fan motor
Install the new fan motor onto the fan housing. Make sure that it has a tight fit. Next, put the fan blade back to the motor drive rod.
Return the radiator assembly
With the motor and blades safely secured on to the housing, the radiator assembly could be placed back to the engine block. Remember to screw and bolt everything nice and tight so they won't inadvertently fall off. Don't forget to couple the wires and the battery cables so the motor can receive electricity. Start the engine and see if the fan is rotating.
Tips and Warnings
- Make sure that the car hasn't been used for a couple of hours because the radiator could get dangerously hot. Without proper protection, nasty burns might be sustained. Wearing protective gears such as safety mechanic gloves provide maximum grip, handling and protection during the installation.
- Don't mix all the nuts, bolts and screws together. Separate them in different containers so you won't get confused as to what goes where.
