🔧 Juke - Water Pump Replacement

On your Juke, the water pump circulates coolant through the engine and radiator to prevent overheating. Replacing it means draining coolant, removing the drive belt and pump, installing the new pump with a fresh seal, then refilling and bleeding air from the cooling system.

Difficulty Level: Advanced | Estimated Time: 3-6 hours

Assumption: This covers the common external (front-of-engine) water pump. If your pump is driven by the timing chain behind the timing cover, the job is significantly larger.

⚠️ Safety & Precautions

• ⚠️ Never open the cooling system hot; let the engine cool fully.
• ⚠️ Support the vehicle on jack stands before working underneath.
• ⚠️ If you loosen/remove a side engine mount, support the engine with a floor jack and wood block first.
• ⚠️ Coolant is toxic; use a drain pan and keep it away from pets/children.
• ⚠️ Disconnect the negative battery terminal if you’ll be working near the starter/alternator area.

📋 Before You Begin

• Park on level ground, set the parking brake, and place wheel chocks behind the rear wheels.
• Let the engine cool completely (radiator hoses should feel cool).
• Disconnect the battery using a 10mm socket on the negative terminal.
• Raise the front with a floor jack and support it on jack stands.
• Place a drain pan under the radiator area.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Remove the lower splash shield

• Use a trim clip removal tool and 10mm socket to remove the clips/bolts holding the lower engine undertray.
• Set the undertray and hardware aside in a small pile so nothing gets lost.

Step 2: Drain the coolant

• Remove the radiator cap (or reservoir cap) slowly by hand once the engine is cool.
• Open the radiator drain (petcock) using a flathead screwdriver if needed.
• Let coolant drain fully into the drain pan.

Step 3: Remove the right-front wheel and inner liner (for access)

• Use a 17mm socket to remove the lug nuts and remove the wheel.
• Use a trim clip removal tool and 10mm socket to remove the right-front inner fender liner fasteners as needed for access.

Step 4: Support the engine (if the right-side mount blocks access)

• Position a floor jack (rated 2-ton minimum) under the engine oil pan area with a wood block (2x4) between the jack and pan.
• Jack up lightly until the engine weight is supported. Just snug—don’t lift the car.

Step 5: Remove the serpentine belt

• Use a serpentine belt tool or 14mm wrench on the belt tensioner and rotate to relieve tension.
• Slip the belt off one pulley and slowly release the tensioner.
• Note the belt routing (take a quick photo with your phone).

Step 6: Move any obstructing brackets/hoses

• Use a 10mm socket and 12mm socket to remove any small brackets blocking water pump access.
• Use hose clamp pliers to slide spring clamps back, then twist hoses gently by hand to break them free (don’t pry hard on plastic fittings).

Step 7: Remove the water pump

• Place shop towels under the pump area—more coolant will spill.
• Use a 10mm socket and 12mm socket to remove the water pump bolts.
• Remove the pump from the engine. If it’s stuck, tap gently with your hand—avoid prying against aluminum sealing surfaces.

Step 8: Clean the sealing surface

• Use a plastic razor blade scraper and shop towels to remove old gasket material and residue.
• Finish with a gasket scraper only if needed, using very light pressure. Clean and flat is the goal.

Step 9: Install the new water pump and seal

• Install the new gasket/O-ring onto the new pump (match orientation exactly).
• Set the pump into place and hand-start all bolts to avoid cross-threading.
• Use a 3/8" torque wrench to tighten water pump bolts evenly in a crisscross pattern: Torque to 12 Nm (9 ft-lbs).

Step 10: Reinstall hoses, brackets, and the serpentine belt

• Reinstall hoses using hose clamp pliers to position clamps back where they were.
• Reinstall brackets using a 10mm socket and 12mm socket.
• Route the belt correctly, then use a serpentine belt tool or 14mm wrench to rotate the tensioner and slip the belt on.

Step 11: Reassemble wheel well and undertray

• Reinstall the inner fender liner using a trim clip removal tool and 10mm socket.
• Reinstall the wheel using a 17mm socket, then lower the vehicle and torque lug nuts: Torque to 113 Nm (83 ft-lbs).
• Reinstall the splash shield using a trim clip removal tool and 10mm socket.

Step 12: Refill and bleed the cooling system

• Close the radiator drain.
• Fill the radiator slowly using a funnel with Nissan-approved coolant (blue long-life, 50/50 premix).
• Fill the coolant reservoir to the MAX line.
• If equipped, open the cooling system air bleeder (a small screw/plug used to let trapped air out) using an 8mm socket, then close it once coolant flows without bubbles.
• Reconnect the battery using a 10mm socket on the negative terminal.

Step 13: Warm up and top off

• Start the engine and let it idle with the heater set to HOT.
• Watch the temperature gauge and check for leaks with a flashlight.
• Once the radiator fan cycles on/off, shut the engine off and let it cool.
• Top off the reservoir to the MAX line if needed.

✅ After Repair

• Inspect for leaks around the water pump and hose connections after the first drive.
• Recheck coolant level the next morning (engine cold) and top off as needed.
• Listen for belt squeal; if present, recheck belt routing and tensioner operation.
• Dispose of old coolant properly (never dump onto the ground).
