3. Drain the Coolant

Place a drain pan under the radiator.
Open the radiator drain valve to drain the coolant.
- Sub-step: If the vehicle is equipped with a drain plug, use it; otherwise, remove the lower radiator hose.

4. Remove the Water Pump

Disconnect hoses connected to the water pump.
- Tools required: Hose clamp pliers.
Unbolt the water pump from the engine block.
- Note: Torque specifications will vary; consult the service manual for specifics.
Carefully remove the water pump and inspect the gasket for signs of wear or damage.

5. Install the New Water Pump

Clean the mounting surface on the engine block to ensure a proper seal.
Place a new gasket or sealant on the new water pump.
Position the new water pump and bolt it into place, tightening to manufacturer specifications.
Reconnect hoses and electrical connectors.

6. Refill the Cooling System

Close the radiator drain valve or reattach the lower radiator hose.
Refill the cooling system with the appropriate coolant type as specified in the owner's manual.
Start the engine and let it reach operating temperature, checking for leaks.

7. Reassemble Engine Covers

Reattach any engine covers that were removed.
Ensure all fasteners are tightened properly.
