Instructions:
1. Start by draining the radiator or coolant reservoir. The drain plug is usually located at the bottom of the radiator. Place a bucket or drain pan underneath the plug before removing it. Once all of the coolant has been drained, replace the plug.
2. Locate the water pump. It is usually mounted on the front of the engine, near the bottom. The water pump has a pulley that is connected to the serpentine belt.
3. Disconnect the hoses that are attached to the water pump. Use a wrench to loosen the hose clamps and then carefully remove the hoses. Be careful not to spill any coolant.
4. Remove the belt that is connected to the water pump. Use a wrench to loosen the belt tensioner and then slide the belt off of the pulley.
5. Remove the bolts that hold the water pump in place. Use a wrench to loosen the bolts and then remove them with your fingers.
6. Remove the old water pump. Gently pry the water pump off of the engine. Be careful not to damage the gasket that is between the water pump and the engine.
7. If replacing the thermostat, now is the time. Follow the steps provided with your new thermostat to install it properly.
8. Install the new water pump. Place the new gasket between the water pump and the engine and then hand-tighten the bolts. Make sure that the gasket is properly seated.
9. Torque the bolts to the specified tightness. Use a torque wrench to tighten the bolts to the specified torque. The torque specification for the water pump bolts can be found in the vehicle's repair manual.
10. Reattach the hoses that are attached to the water pump. Use a wrench to tighten the hose clamps.
11. Reattach the belt that is connected to the water pump. Rotate the tensioner pulley clockwise to release tension and slide the belt to its proper position.
12. Close the radiator or coolant reservoir.
13. Add coolant. You can use either the coolant the vehicle uses, or a 50/50 mix of antifreeze and water.
14. Start the engine. Let it run at idle for a few minutes until it reaches operating temperature.
15. Check for leaks. Look for any leaks around the water pump, hoses, and thermostat housing. Tighten any loose connections.
