How to Replace a Water Pump
DIY Complexity: Moderate
DIY Time: 3.5 hours
1. Water Pump
3. 3/8 in. Drive Ratchet
4. Cooling System Pressure Tester
5. Needle Nose Pliers
6. Socket Set
7. Radiator Hook Tool
2. Silicone Sealant
Step 1 * With the engine off and cold, open the hood and locate the vehicle’s water pump.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.
o Tip: Before removing the radiator cap, squeeze the upper radiator hose to verify that the cooling system is not pressurized.
Step 2 * Remove the radiator cap.
Step 3 * Install cooling system pressure tester. Apply the pressure indicated on the radiator cap or in the owner’s manual.
Step 4 * Inspect cooling system components for leaks.
Step 5 * Place a drain pan under the radiator. Open drain valve or remove the lower radiator hose to drain cooling system.
o Tip: Depending on the vehicle, lifting the vehicle may be required to gain access to the lower radiator hose.
Step 6 * Remove the drive belts or serpentine belt.
Step 7 * Remove any hoses connected to water pump.
Step 8 * Unbolt water pump from engine. Remove the water pump.
Step 9 * Using a gasket scraper, clean the mating surface on the engine block.
Step 10 * Install new water pump and new gasket. Tighten bolts to manufacturer’s specifications.
o Tip: You may want to use a light bead of silicone designed for water pumps.
Step 11 * Re-install any hoses and belts that were removed.
Step 12 * Re-install drain plug or lower radiator hose.
o Tip: Squeeze the radiator hose. If it feels soft you may want to replace the hose at this time. Always use new hose clamps.
Step 13 * Refill radiator with a 50/50 mix of coolant and distilled water, then pressure test the cooling system and check for leaks.
Step 14 * Fill overflow reservoir with same mixture.
Step 15 * Leave the radiator cap off, start engine and let it idle. You should see the system“burping” bubbles of air. Refill the radiator to the top.
o Tip: Most air is expelled after a couple minutes of idling. Be cautious of potentially hot fluid overflowing.
Step 16 * Install radiator cap.
Step 17 * Road test vehicle, keep an eye on the engine temp gauge if vehicle runs hot, there still might be an air pocket in the cooling system. The cooling system should be topped off after vehicle has fully cooled down.
Good luck (remember rated this help).
