Water Pump: Removal and Installation

WARNING:

Never remove the radiator cap when the engine is hot. Serious burns could occur from high pressure engine coolant escaping from the radiator. Wrap a thick cloth around the cap. Slowly turn it a quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

2) Drain engine coolant from radiator. Refer to [Changing Engine Coolant] Service and Repair.

CAUTION:
- Perform this step when the engine is cold.
- Do not spill engine coolant on drive belt.

3) Remove cooling fan and water pump pulley. Refer to [Cooling Fan: Removal and Installation (Crankshaft driven type)] Crankshaft Driven Type.
4) Remove water pump with power tool.
