🔧 F-150 - Engine Mount Replacement

Replacing both engine mounts requires supporting the 5.0L engine, raising it slightly, and removing each mount through the wheel-well area. Access is tight, and the engine must remain securely supported throughout the repair.

Difficulty Level: Advanced | Estimated Time: 6-9 hours

Assumption: This procedure covers the left and right engine mounts; 4WD models require additional front-axle clearance described below.

⚠️ Safety & Precautions

• ⚠️ Never work beneath an engine supported only by a floor jack.
• ⚠️ Use an engine support bar before loosening either mount.
• ⚠️ Raise the engine only enough to unload the mounts; excessive movement can damage wiring, hoses, the fan, or exhaust.
• ⚠️ Keep hands out of the space between the engine, mounts, and frame while changing engine height.
• ⚠️ Support the truck on jack stands placed beneath the frame, not the suspension.
• ⚠️ Disconnect the negative battery cable because the starter and heavy-gauge electrical connections are near the right mount.
• ⚠️ Allow the exhaust system and engine to cool completely before starting.
• ⚠️ On 4WD models, front differential or axle interference can require professional lifting equipment. Do not force the mount past the axle.

📋 Before You Begin

• Park your F-150 on solid, level ground. Shift to Park, apply the parking brake, and chock both rear wheels.
• Let the engine and exhaust cool completely.
• Open the hood before disconnecting the battery. No infotainment service mode is required.
• Use an 8mm socket to disconnect the negative battery terminal. Isolate the cable so it cannot spring back.
• Remove loose items from the engine compartment before installing the engine support bar.
• Inspect the fan-to-shroud clearance, radiator hoses, wiring, intake duct, and exhaust connections. These must not stretch as the engine rises.
• An engine support bar spans the fender structure and holds the engine from above. Do not rest it on plastic trim or unsupported sheet metal.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Raise and Secure the Truck

• Use the 3-ton floor jack beneath an approved front frame lifting point to raise your F-150.
• Place the 3-ton jack stands beneath both frame rails, then lower the truck onto them.
• Keep the floor jack lightly touching the front crossmember as a backup, but do not rely on it for support.
• Use a 21mm socket to remove both front wheels. Mark each wheel position with the paint marker.
• Shake the truck gently to verify stability.

Step 2: Remove the Wheel-Well Liners

• Use an 8mm socket and trim-clip removal tool to remove the fasteners from both front wheel-well liners.
• Use a flat-blade screwdriver only where needed to release reusable clips without tearing the liners.
• Pull the liners outward and place their fasteners into separate left and right groups.

Step 3: Create Upper Engine Clearance

• Use an 8mm socket to loosen the air-intake duct clamps.
• Release the electrical connector and breather fittings by hand, then remove the intake duct and air-cleaner outlet tube.
• Use a 10mm socket to release any coolant reservoir or wiring brackets that could become tight when the engine moves. Do not disconnect hoses unless clearance requires it.
• If a coolant hose must be disconnected, place the 2-gallon drain pan underneath and release the clamp with mechanic gloves and the appropriate pliers supplied with the replacement clamp.

Step 4: Install the Engine Support Bar

• Position the 1,000-pound engine support bar across the reinforced fender mounting structures according to the support-bar instructions.
• Connect the 1,000-pound lifting chain to the factory engine lifting point. Do not attach it to the intake manifold, exhaust manifold, or accessory brackets.
• Tighten the support-bar screw by hand until the chain is snug and the engine’s weight is supported.
• Use the LED work light to check that the chain and support feet cannot contact wiring, hoses, or painted panels.

Step 5: Remove the Lower Mount Retainers

• Use the LED work light to locate the left and right mount-to-frame retaining nuts through the wheel wells and beneath the truck.
• Mark the installed position of each mount with the paint marker.
• Use an 18mm deep socket, 12-inch extension, universal-joint adapter, and breaker bar to loosen the lower mount retainers.
• Remove the retainers with the 18mm deep socket and ratchet. Do not raise the engine yet.

Step 6: Release Mount Brackets as Required

• Use a 15mm deep socket, extensions, and universal-joint adapter to remove the mount-to-engine bracket fasteners accessible through each wheel well.
• Use a 15mm combination wrench where the socket cannot remain straight.
• Keep the left and right fasteners separated because their access and bracket positions differ.
• Do not loosen exhaust-manifold fasteners or pry against the aluminum engine block.

Step 7: Raise the Engine Slightly

• Turn the engine support-bar screw slowly with its supplied handle until each mount is just free of frame tension.
• Watch the fan, shroud, radiator hoses, heater hoses, wiring, transmission cooler lines, and exhaust while raising the engine.
• Limit engine movement to the minimum necessary for mount removal. Stop immediately if anything stretches or contacts the body.
• A few millimeters is often enough.

Step 8: Remove the Right Engine Mount

• Use the LED work light to verify the negative battery cable remains disconnected and isolated.
• Guide the right mount away from its bracket and frame by hand while maintaining engine support.
• If the mount catches, adjust the engine support-bar screw slightly. Never force it with the flat-blade screwdriver.
• On 4WD models, stop if the mount cannot clear the front axle or differential without removing drivetrain components. Front differential removal requires separate axle-support and alignment procedures.

Step 9: Install the Right Engine Mount

• Compare the replacement mount with the removed mount. Match the locating tabs, stud direction, heat shield, and bracket shape.
• Position the new right mount by hand using the paint marks as a guide.
• Install all fasteners by hand for several turns. This prevents cross-threading.
• Use a 15mm socket and ratchet to snug the mount-to-engine bracket fasteners without fully tightening them.
• Install the lower mount retainer by hand and leave it loose.

Step 10: Replace the Left Engine Mount

• Use the engine support-bar screw to make only the small height adjustment required to unload the left mount.
• Guide the old left mount out through the wheel-well opening by hand.
• Position the new left mount with its locating features matching the original orientation.
• Install the bracket fasteners and lower retainer by hand, then snug them with the 15mm and 18mm sockets.
• Do not fully tighten either mount while the engine remains raised.

Step 11: Settle and Tighten the Mounts

• Slowly loosen the engine support-bar screw until the engine’s full weight rests naturally on both mounts.
• Confirm that both locating tabs are seated and no hose, wire, or heat shield is trapped.
• Use the torque wrench and correct socket to tighten the engine-mount bracket fasteners to 70 Nm (52 ft-lbs).
• Use the torque wrench and 18mm deep socket to tighten the mount-to-frame retainers to 63 Nm (46 ft-lbs).
• Torque specifications apply to clean, dry threads. Replace damaged or self-locking fasteners.

Step 12: Remove the Engine Support Equipment

• Verify all mount fasteners are tightened before removing support.
• Disconnect the lifting chain by hand and remove the engine support bar carefully.
• Use the LED work light to inspect the lifting point and surrounding wiring for damage.

Step 13: Reassemble the Engine Compartment

• Use a 10mm socket to reinstall any coolant reservoir and wiring brackets removed for clearance.
• Reinstall the intake duct and reconnect its breather fittings and electrical connector by hand.
• Use an 8mm socket to tighten the intake clamps until secure. Do not crush the plastic duct.
• If coolant was lost, refill the cold reservoir with a 50/50 mixture of specified Ford coolant and distilled water.

Step 14: Reinstall the Liners and Wheels

• Use the trim-clip removal tool by hand to reinstall reusable clips, then use an 8mm socket to install the wheel-well liner screws.
• Install the wheels in their marked positions and snug the lug nuts in a star pattern with a 21mm socket.
• Use the 3-ton floor jack to raise the truck, remove the jack stands, and lower it completely.
• Use the torque wrench and 21mm socket to tighten the wheel lug nuts in a star pattern to 204 Nm (150 ft-lbs).

Step 15: Reconnect the Battery

• Use an 8mm socket to reconnect the negative battery terminal.
• Tighten the terminal only until it cannot rotate by hand. Do not overtighten the terminal clamp.
• Remove all tools from the engine compartment before closing the hood.

✅ After Repair

• Start the engine with the hood open. Keep hands and tools away from the belt and fan.
• Observe the engine at idle while a helper shifts between Park, Reverse, and Drive with the brake firmly applied. Excessive lifting or knocking indicates a loose or misaligned mount.
• Check for coolant leaks and verify the cold coolant level after the engine cools again.
• Take a short, low-speed test drive. Listen for clunks during acceleration, braking, and gear changes.
• Recheck visible mount fasteners and wheel-lug torque after the test drive.
• The clock and one-touch window functions may need resetting after battery disconnection. No battery registration or coding is required.
