Safety Tip: Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or closed toe shoes.
1
With the engine off and cold, open the hood and locate the vehicle's radiator and water pump.
2
Remove the radiator cap.
3
Install a pressure tester on the radiator. Apply the pressure indicated on the radiator cap or in the owner's manual.
4
Inspect the water pump for leaks. Remove the pressure tester.
5
Place a drain pan under the radiator. Open the drain valve or remove the lower radiator hose to drain the cooling system.
6
Remove the drive belts or serpentine belt.
7
Remove any hoses connected to the water pump.
8
Unbolt the water pump from the engine. Remove the water pump.
9
Using a gasket scraper, clean the mounting surface on the engine block.
10
Install a new gasket and attach the new water pump to the engine with the original mounting bolts. Tighten the bolts to the manufacturer's specifications.
11
Re-install any hoses and belts that were removed.
12
Re-install the drain plug or lower radiator hose.
13
Refill the radiator with a 50/50 mix of coolant and distilled water. Pressure test the cooling system and check for leaks.
14
Check and fill the overflow reservoir with coolant.
15
Leave the radiator cap off and start the engine. Idle the engine to remove trapped air from the cooling system. Add coolant if necessary.
16
Install the radiator cap.
17
Road test the vehicle and monitor the temperature gauge. If the vehicle runs hot, there may be an air pocket in the cooling system. Allow the engine to cool off and add the necessary coolant.
