Water Pump Removal/Installation: Notes

WARNING:

• Never remove the cooling system cap or loosen the radiator drain plug while the engine is running, or when the engine and radiator are hot. Scalding engine coolant and steam may shoot out and cause serious injury. It may also damage the engine and cooling system.
• Turn off the engine and wait until it is cool. Even then, be very careful when removing the cap. Wrap a thick cloth around it and slowly turn it counterclockwise to the first stop. Step back while the pressure escapes.
• When you are sure all the pressure is gone, turn the cap using the cloth, and remove it.

NOTE:

• Coolant may have accumulated depending on how many years the water pump has been in use. However, this does not indicate a malfunction if the accumulated coolant does not cover the vapor escape hole.

1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION .)
2. Disconnect the negative battery cable.
3. Remove the aerodynamic under cover and splash shield as a single unit. (See AERODYNAMIC UNDER COVER REMOVAL/INSTALLATION .) (See SPLASH SHIELD REMOVAL/INSTALLATION .)
4. Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT .)
5. Loosen the water pump pulley bolts before removing the drive belt.
6. Remove the drive belt. (See DRIVE BELT REMOVAL/INSTALLATION .)
7. Remove in the order indicated in the table.
8. Install in the reverse order of removal.
9. Refill the engine coolant. (See ENGINE COOLANT REPLACEMENT .)
10. Inspect for engine coolant leakage. (See ENGINE COOLANT LEAKAGE INSPECTION .)
