Repair Procedures

Removal

1. Loosen the drain plug, and drain the engine coolant.

WARNING:
Never remove the radiator cap when the engine is hot. Serious scalding could be caused by hot fluid under high pressure escaping from the radiator.

2. Remove the drive belt (A).




3. Remove the drive belt (A).




4. Remove the water pump (A) and the gaskets (B).










Inspection

1. Check each part for cracks, damage or wear, and replace the coolant pump assembly if necessary.
2. Check the bearing for damage, abnormal noise and sluggish rotation, and replace the coolant pump assembly if necessary.
3. Check for coolant leakage. If coolant leaks from hole, the seal is defective. Replace the coolant pump assembly.

NOTE:
A small amount of "weeping" from the bleed hole is normal.

Installation

1. Install the water pump (A) with the new gaskets (B).









NOTE:
- Clean the contact face before assemble.
- Always use a new gaskets.
