• Use a drain pan and keep coolant away from children and pets.
• Disconnect the negative battery cable before working near the belt and fan area.
• Do not run the engine with the drive belt removed for more than a few seconds.
• Replace the coolant with the correct Nissan-spec long-life coolant and bleed air from the system after refill.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Drain the coolant

• Place a drain pan under the radiator.
• Open the radiator drain with a plastic trim tool or by hand if equipped.
• Remove the radiator cap only after the engine is cool.
• Drain the coolant completely and tighten the drain when finished.

Step 2: Remove the drive belt

• Use a serpentine belt tool (specialty) or 14mm socket on the belt tensioner.
• Rotate the tensioner to release belt tension.
• Slip the belt off the pulleys and remove it from the engine bay.
• Take a quick belt routing photo first.

Step 3: Access the water pump

• Use a 10mm socket to remove any splash shield or access cover blocking the pump area.
• Set the fasteners aside in order.

Step 4: Remove the water pump

• Use a 12mm socket to remove the water pump bolts.
• Loosen the bolts evenly so the pump comes off without binding.
• Pull the pump away from the engine and catch any remaining coolant.
• Remove the old gasket and clean the mating surface with a gasket scraper.
• Torque on installation: 12 N·m (106 in-lbs)

Step 5: Install the new water pump

• Install the new gasket on the pump or engine side, depending on the part design.
• Position the new pump and start all bolts by hand with a 12mm socket.
• Tighten the bolts evenly in a crisscross pattern.
• Torque the water pump bolts to 12 N·m (106 in-lbs)

Step 6: Reinstall the belt and covers

• Use the serpentine belt tool (specialty) or 14mm socket to release the tensioner again.
• Route the belt back on all pulleys exactly as before.
• Reinstall any splash shields or covers with a 10mm socket.

Step 7: Refill and bleed the cooling system

• Use a funnel to refill with the correct coolant mix.
• Fill the radiator and reservoir to the proper level.
• Start the engine and let it idle with the radiator cap off if allowed by the fill procedure.
• Watch for air bubbles and top off coolant as the level drops.
• Install the cap when the system is full and stable.

Step 8: Recheck for leaks

• Use a flashlight and shop towels to inspect the pump, hose connections, and drain area.
• Look for seepage while the engine is warm and again after a short road test.

✅ After Repair

• Monitor the temperature gauge on the first drive.
• Check coolant level again after the engine cools completely.
• Recheck for leaks around the pump, radiator drain, and hoses.
• If the heater blows cold, repeat the bleed process to remove trapped air.
