🔧 Edge - Water Pump Replacement

The water pump circulates coolant through your engine and radiator. If it leaks or the bearing fails, you can overheat quickly, so replacement is important to protect the engine.

Difficulty Level: Intermediate | Estimated Time: 2.5-4.0 hours

Assumption: Your Edge has the 2.0L EcoBoost belt-driven (external) water pump.

⚠️ Safety & Precautions

• ⚠️ Never open the coolant cap hot; let the engine cool fully.
• ⚠️ Support the vehicle with jack stands; never rely on a jack.
• ⚠️ Coolant is toxic—keep away from kids/pets and clean spills.
• ⚠️ Keep fingers clear of the belt tensioner; it’s spring-loaded.
• 🔋 Battery disconnect is recommended if your hands/tools will be near the alternator wiring.

📋 Before You Begin

• Park on level ground, set the parking brake, and chock the rear wheels.
• Let the engine cool completely (upper radiator hose should feel cool).
• Slowly loosen the coolant reservoir cap to release any remaining pressure.
• If disconnecting the battery: use a 10mm socket to remove the negative terminal and isolate it.
• Take a photo of the belt routing before removal. Phones are your best “memory tool.”

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise the front-right corner and remove the wheel

• Use a 19mm socket to loosen the lug nuts slightly while on the ground.
• Lift with a floor jack and support with jack stands under a solid lift point.
• Remove the lug nuts using a 19mm socket and take the wheel off.

Step 2: Remove the splash shield / inner fender liner for access

• Remove fasteners using a 7mm socket and Torx T25/T30 bit (varies by fastener).
• Use a trim clip removal tool for push-pins (this tool pops clips out without breaking them).
• Move the liner aside to expose the belt drive area.

Step 3: Drain the coolant

• Place a drain pan (at least 10-quart) under the radiator drain area.
• Use a flathead screwdriver (or the appropriate socket set size if equipped) to open the radiator drain valve slowly.
• Let coolant drain fully, then close the drain valve.

Step 4: Remove the serpentine belt

• Locate the belt tensioner.
• Use a serpentine belt tool (a long handle made to safely rotate the tensioner) to rotate the tensioner and relieve belt tension.
• Slip the belt off the water pump pulley area first, then remove the belt from the remaining pulleys.

Step 5: Remove the water pump pulley (if it blocks pump bolts)

• Use a 10mm socket to remove the pulley bolts while holding the pulley from turning with a breaker bar braced carefully.
• Remove the pulley and set it aside.
• During reassembly: Torque to 25 Nm (18 ft-lbs).

Step 6: Remove the water pump

• Place the drain pan under the pump—more coolant will spill.
• Remove the water pump bolts using a 10mm socket.
• Carefully pull the pump away from the engine. If it’s stuck, tap lightly with the handle of a ratchet—do not pry hard on sealing surfaces.

Step 7: Clean the sealing surface

• Use a plastic gasket scraper and shop rags to clean the engine’s sealing surface.
• Do not gouge the metal. Clean and flat prevents leaks.

Step 8: Install the new water pump

• Install the new gasket/O-ring onto the new pump (match how the old one was seated).
• Position the pump and start all bolts by hand to avoid cross-threading.
• Tighten bolts evenly in a crisscross pattern using a 1/4" drive torque wrench.
• Torque to 10 Nm (89 in-lbs).

Step 9: Reinstall pulley and belt

• Reinstall the pulley and bolts using a 10mm socket.
• Torque to 25 Nm (18 ft-lbs) using a 3/8" drive torque wrench.
• Route the belt according to your photo, then rotate the tensioner using the serpentine belt tool and slip the belt fully into place.
• Visually confirm the belt is seated in every pulley groove.

Step 10: Reinstall splash shield and wheel

• Reinstall the liner using the 7mm socket, Torx T25/T30 bit, and trim clip removal tool (for clips).
• Install the wheel and snug lug nuts using a 19mm socket.
• Lower the vehicle and torque lug nuts with a torque wrench: Torque to 162 Nm (120 ft-lbs).

Step 11: Refill and bleed the cooling system

• Mix coolant 50/50 using Ford-approved OAT coolant and distilled water (unless you purchased premix).
• Fill the reservoir slowly using a funnel to the MAX line.
• Start the engine and set HVAC to full HOT (this opens coolant flow through the heater core).
• Let it idle and watch the coolant level; top off as it drops.
• Once warm, shut it off, let it cool, then recheck and top off to MAX.

✅ After Repair

• Inspect for leaks with the engine running: around the pump, pulley area, and under the vehicle.
• Verify the heater blows hot and the temperature gauge stays normal.
• After your first drive, let it cool and recheck coolant level again.
• Dispose of old coolant properly (parts stores often accept it).
