🔧 Water Pump - Replacement

This job replaces the engine coolant pump and its seal, which is the part that circulates coolant through the engine. On your Equinox, the water pump is serviced from the accessory-drive side, so you’ll remove the belt and related access parts first, then swap the pump and refill the cooling system.

Difficulty Level: Intermediate | Estimated Time: 3-5 hours

⚠️ Safety & Precautions

• Let the engine cool completely before opening the cooling system. Hot coolant can cause serious burns.
• Keep coolant off the serpentine belt and pulleys. Contamination can damage the belt and cause slipping.
• Use jack stands on a level surface. Never rely on the floor jack alone.
• Disconnect the negative battery cable if you will be working near the starter cable or exposed wiring.
• Dispose of old coolant properly. It is toxic to people and animals.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain the coolant

• Place the drain pan under the radiator drain area.
• Use a flat-blade screwdriver or pliers to open the radiator drain or remove the lower hose, depending on access.
• Drain enough coolant so the level is below the water pump.
• Close the drain once coolant flow stops.

Step 2: Remove the belt and access components

• Use a 15mm socket and breaker bar to rotate the belt tensioner.
• Slip the serpentine belt off the pulleys and remove it.
• If the splash shield or wheelhouse liner blocks access, remove it with a 10mm socket.
• Tip: Route the belt out slowly so you remember its path.

Step 3: Remove hoses and connectors from the water pump

• Use pliers to release any spring clamps on the hoses.
• Pull the coolant hoses off the water pump necks.
• Move the hoses aside and plug them if needed to limit coolant mess.

Step 4: Remove the water pump

• Use a 10mm socket or 13mm socket to remove the water pump bolts.
• Remove the pump from the engine.
• If it is stuck, gently work it loose with a plastic trim tool or careful hand pressure. Do not pry hard on the sealing surface.
• Remove the old gasket or seal.

Step 5: Clean the mounting surface

• Use a gasket scraper and pick tool to remove old gasket material.
• Clean the surface until it is smooth and dry.
• Do not scratch the aluminum housing.

Step 6: Install the new water pump

• Install the new gasket or seal on the new pump.
• Position the pump on the engine and start all bolts by hand.
• Use a 10mm socket or 13mm socket to tighten the bolts evenly in a crisscross pattern.
• Torque to 22 Nm (16 ft-lbs).

Step 7: Reconnect hoses and reinstall the belt

• Push the coolant hoses back onto the pump and reinstall the clamps with pliers.
• Reinstall the serpentine belt using the 15mm socket and breaker bar on the tensioner.
• Make sure the belt sits correctly in every pulley groove.
• Reinstall any splash shield or access covers with a 10mm socket.

Step 8: Refill the cooling system

• Use a funnel to refill the system with the correct coolant.
• Fill slowly to reduce air pockets.
• If your fill neck has a bleed screw, open it until coolant flows steadily, then close it.
• Tip: Slow filling helps prevent trapped air.

Step 9: Bleed air from the system

• Start the engine and let it idle with the heater set to hot.
• Watch the coolant level and top it off as the thermostat opens.
• Look for steady heat from the vents and stable coolant level.
• Shut the engine off, let it cool, and recheck the level.

✅ After Repair

• Check for leaks around the pump, hoses, and drain area.
• Verify the serpentine belt tracks correctly and runs quietly.
• After a full cool-down, recheck coolant level in the reservoir and top off if needed.
• Test-drive the vehicle and monitor engine temperature.
