FAN-RADIATOR
DESCRIPTION
The electric cooling fan replaces the engine driven mechanical fan. The electric cooling fan is integral to the fan shroud and is located between the radiator and the engine.
The electric fan is controlled by the electronic control module (ECM).
The electric cooling fan is not serviceable. Any failure of the fan blade, electric motor or fan shroud requires replacement of the fan module.
CAUTION: Do not attempt to service the electric cooling fan or fan blades separately, replace the cooling module as an assembly. Failure to do so may cause severe damage to the electric cooling fan assembly.
REMOVAL
1. Drain cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
2. Remove upper radiator hose (3).
3. Remove hose (2).
4. Remove the coolant recovery container (1) and position out of the way.
5. Disconnect the electrical connector (1).
6. Remove radiator upper seal (2).
7. Remove the mounting screws.
8. Remove the cooling fan assembly .
CLEANING
Clean the fan blades using a mild soap and water. Do not use an abrasive to clean the blades.INSPECTION
WARNING: Do not attempt to bend or straighten fan blades if fan is not within specifications.
CAUTION: If fan blade assembly is replaced because of mechanical damage, water pump and viscous fan drive should also be inspected. These components could have been damaged due to excessive vibration.
1. Remove fan blade assembly from viscous fan drive unit (four bolts).
2. Lay fan on a flat surface with leading edge facing down. With tip of blade touching flat surface, replace fan if clearance between opposite blade and surface is greater than 2.0 mm (.090 inch). Rocking motion of opposite blades should not exceed 2.0 mm (.090 inch). Test all blades in this manner.
3. Inspect fan assembly for cracks, bends, loose rivets or broken welds. Replace fan if any damage is found.
INSTALLATION
1. Position the cooling fan assembly.
2. Install mounting screws. Tighten to 5.5 N·m (50 in. lbs.)
3. Install upper radiator hose (3)
4. Install upper radiator seal (2).
5. Connect the electrical connector (1).
6. Fill cooling system (Refer to 7 - COOLING - STANDARD PROCEDURE).
