Radiator Fan Motor Replacement
Step 1 - Locate and disconnect the electrical connector for the cooling fan.
Disconnect Cooling Fan Electrical Connector Step 2 - Next, remove the lower mounting bolts that attach the fan to the radiator. (Note: Some vehicles have alignment dowels which need not be removed.)
Removing Lower Fan Mounting Bolts
Remove Weather Stripping Step 4 - Then, loosen mounting bolts or clips to remove any plastic shielding that will inhibit the replacement of the cooling fan.
Remove Plastic Covering Step 5 - Once all mounting bolts have been removed, lift the plastic covering from the vehicle.
Plastic Cover Removed (Grill) Step 6 - After the plastic covers have been removed, loosen and remove the core support mounting bolts. (Note: This is not needed in some vehicles.)
Remove Core Support Bolts Step 7 - Next, lift the core support from the vehicle. (Note: A hood cable release could be mounted to this support.)
Core Support Removed Step 8 - Then, loosen the upper radiator hose clamp using a hose clamp tool or channel locks.
Loosen Upper Radiator Hose Clamp Step 9 - Once the clamp has been loosened, grasp the hose and twist using a hose pick or screwdriver to assist. Have a fluid catch basin ready as coolant will leak out. (Note: Depressurize or drain the radiator if needed. Radiator replacement.)
Remove Upper Radiator Hose Step 10 - After the upper radiator hose has been removed, undo the mounting clips or bolts that hold the air intake in position. (Note: This step needed only if the air intake is blocking the removal of the cooling fan.)
Remove Air Intake Step 11 - Next, loosen and remove the upper mounting bolts from the cooling fan radiator mount.
Remove Upper Cooling Fan Bolts Step 12 - Once all mounting bolts and clips have been removed, gently lift the cooling fan from the engine bay. Use caution when performing this action as to not damage the radiator cooling fins.
Removing Cooling Fan Step 13 - After the failed cooling fan has been removed, compare the old fan to the replacement cooling fan. Inspect mounting tabs and electrical connector to ensure proper installation. (Note: Some cooling fan designs feature the replacement motor separate.)
Matching Failed Fan to Replacement Fan Step 14 - Gently lower the new cooling fan down into the engine bay and onto the radiator. Again, use caution when performing this as not to damage the radiator cooling fins.) Reassembly all mounting bolts etc., refill cooling system and check the coolant reservoir, add fluid as needed.
Installing New Cooling Fan Once these steps have been completed, simply reverse the order to reassemble. Start the engine and turn the air conditioner "ON", or wait until the engine reaches operating temperature to check for fan operation and recheck coolant level. Tools and Supplies Needed
- Socket set
- Wrench set
- Replacement cooling fan
- Fluid catch basin
- Protective eyewear and gloves
- Hose clamp tool or channel locks
- 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. If the fans turn "ON" and the engine overheats anyway, check for engine overheating
- Use caution while replacing the cooling fan, if radiator damage occurs it must be replaced.
