Removal
Removal-All Engines
If the water pump is replaced because of bearing or shaft damage, the mechanical cooling fan should be inspected for fatigue cracks, loose blades, or loose rivets that could have resulted from excessive vibration. Replace the fan if any of these conditions are found.
The water pump can be removed and installed without discharging the air conditioning system.
1. Drain cooling system.
2. If equipped with air-conditioning, remove the radiator.
CAUTION: Do not place viscous fan in upright position. The silicone fluid in the viscous drive could drain into the bearing assembly and contaminate the lubricant.
