The radiator cooling fan lowers the temperature level of your car radiator and prevents your car from overheating. The cooling fan increases the air circulation through the radiator. The fan must be install properly to prevent overheating and possibly damaging the radiator. There are two types of cooling fan systems. One system is powered by the engine and the other is powered by the battery. Be sure you know which type you have when installing your fan. 

Step 1 – Checking your Owner's Manual

Read your owner's manual to find out whether you have an engine-powered cooling fan or an electric cooling fan. Read the specific information for your vehicle. 

Step 2 – Locating Your Engine-Powered Radiator Cooling Fan

Open your car hood to locate the radiator which is located behind the grill in front of your engine. The cooling fan is attached at the back of the radiator through a mounting frame. 

Step 3 - Disconnecting the Power Supply

An electric cable connects the fan motor to the engine. Disconnect the wires connecting the motor and the engine. Use masking tape and marker to label the connection wires.

Step 4 - Removing the Cooling Fan Housing

Use your wrench to remove the four screws in the corners of the cooling fan housing and the fasteners at the sides. Carefully lift and remove the housing from your engine compartment. Store the housing in a safe place.

Step 5 - Removing the Radiator Cooling Fan and Motor

The blade of your cooling fan is screwed to a shaft. Use your screwdriver to remove the blade from the shaft and the motor from the housing 

Step 6 - Attaching the Replacement Radiator Cooling Fan and Motor

Replace your new cooling fan onto the shaft. Replace the motor into the cooling fan housing. Secure the housing into the car with the screws. Reconnect all of the wires to the power supply. Close the hood of your car.

Step 7 – Locating Your Electric Radiator Cooling Fan

Open your car hood to locate the radiator which is located behind the grill in front of your engine. The cooling fan is attached at the back of the radiator through a mounting frame

Step 8 – Disconnecting the Battery

Disconnect only the positive battery terminal and lay is aside. The negative terminal should not be disconnected because it could accidentally touch metal, causing the battery to reground.

Step 9 – Disconnect the Wiring

Disconnect the hookups for the wiring to the fan. If your fan has a plug, use a screwdriver to push the tabs and pull remove the plug. If your fan has butt connectors, squeeze them until they open. Pull out the wires from the open connectors. Use tape to label the wires so that you will know where they go when you replace them.

Step 10 – Removing the Fan

Cut the retaining clips that hold the fan guard to the radiator and remove them. Remove the old fan from the radiator.

Step 11 – Positioning the New Motor

Place the fan motor into the shroud. Secure the shroud with the nuts. Locate the hole at the center of the fan and slide the motor into it.  Secure the motor by turning the nuts counterclockwise. 

Step 12 – Positioning the Assembly

Ensure that the fan, the motor and shroud assembly are facing the radiator. Carefully place the parts into the engine compartment. Use the screws to secure the shroud to the radiator.

Step 13 – Reconnecting Wires

Reconnect the wires to the motor. Snap and lock the connector into its proper position. Reconnect the battery cables.
