At operating temperature, the engine cooling system is hot and under pressure. Steam can cause personal injury. Check the coolant level only after the engine has been stopped and the fill cap on the radiator is cool enough to touch with your bare hand. Remove the fill cap slowly to relieve pressure. Cooling system conditioner contains alkali. Avoid contact with skin and eyes to prevent personal injury.

Start By:a. remove water pump The water pump seal can be replaced without removing the water pump from the engine.An intermittent leakage of a small amount of coolant from the hole in the water pump housing is not an indication of a water pump seal failure. This is required to provide lubrication for the seal. Replace the water pump seal only if a large amount of leakage or a constant flow of coolant is observed draining from the water pump housing.1. Remove O-ring seal (3) from adapter (4). Remove the adapter from housing (7). Remove the O-ring seal from the outside of the adapter.2. Remove bolt (1) and washer (2). Use Tooling (A) to remove impeller (6) from shaft (13).3. Remove spring and seal (5) from the shaft.4. Remove four bolts (16) from retainer (12) that hold the shaft assembly to the pump housing. Remove O-ring seal (18) from housing (7).5. Remove gear and shaft assembly (17) from the housing. Remove bolt (15), retainer (14), and retainer (12) from the shaft assembly.6. Use a press to remove shaft (13) from the gear. Remove bearing (9), spacer (10), and bearing (11) from the shaft.7. Remove lip-type seal (8) from the housing.8. Turn the housing over, and remove ceramic ring (20) and seal (19) from the housing. The following steps are for the assembly of the water pump.9. Use 6V-1541 Quick Cure Primer and clean shaft (13) and the seal counter bore in the pump housing.10. Install bearing (9), spacer (10), and bearing (11) on shaft (13).11.
