This procedure covers the removal and replacement of the rear engine mount on a 2015-2020 Ford F-150 with the 5.0L Coyote V8 engine, requiring the engine to be supported while the mount is detached from both the engine block and the transmission crossmember.

Tools required

Parts

• Rear engine mount assembly × 1 — Ford OEM DG1Z-6068-A or equivalent

Preparation

1. Park the vehicle on a level, solid surface and engage the parking brake
2. Allow the engine to cool completely if recently operated
3. Disconnect the negative battery cable to prevent electrical issues
4. Raise the front of the vehicle using a floor jack and support securely on jack stands behind the front wheels
5. Remove the front skid plate or lower belly pan if equipped to access the engine from below
6. Inspect the work area and identify the rear engine mount location between the engine block and transmission crossmember

Procedure

1. 1

   Position engine support jack
   Place a floor jack with a wooden block (approximately 12x12 inches) under the oil pan at the rear of the engine. Raise the jack until it just makes contact with the pan but is not bearing significant weight. This will be used to support the engine when the mount is removed.
   ⚠Use a wooden block or rubber pad to distribute the load and prevent damage to the oil pan. Never jack directly on the oil pan with metal.
2. 2

   Remove mount-to-frame fasteners
   Locate the two bolts securing the rear engine mount bracket to the transmission crossmember/frame. These are accessed from below. Use a socket and ratchet to remove these mounting bolts completely. Set bolts aside for reinstallation or replacement.
   ℹ️These bolts may be tight due to thread-locking compound. A breaker bar may be needed for initial loosening.
   Torque spec

   Engine Mount-to-Frame Bolts75 Nm (55 lb-ft)
3. 3

   Support engine weight
   Slowly raise the floor jack under the engine approximately 1/4 to 1/2 inch to transfer the engine weight from the mount to the jack. Watch for any movement and ensure the engine rises evenly. The mount should now be unloaded.
   ⚠Raise the engine slowly and watch for interference with hoses, wiring, or other components. Do not raise more than necessary.
4. 4

   Remove engine-to-mount fasteners
   Locate the bolts securing the rear engine mount to the engine block (typically 2-3 bolts). Use a socket with extension to access these bolts from below or from the side. Remove all bolts securing the mount to the engine block.
   Torque spec

   Engine Mount-to-Block Bolts65 Nm (48 lb-ft)
5. 5

   Remove rear engine mount
   With all fasteners removed and the engine supported, carefully maneuver the rear engine mount out of position. It may require slight rotation or angling to clear the engine block and crossmember. A pry bar may be needed to separate the mount if it is stuck to the mounting surfaces.
6. 6

   Inspect mounting surfaces
   Inspect the engine block mounting surface and crossmember mounting surface for damage, cracks, or excessive wear. Clean both surfaces with a wire brush to remove any rust, debris, or old gasket material. Check that mounting bolt holes are clean and threads are in good condition.
   ℹ️If mounting surfaces show cracks or severe damage, further inspection and repair may be required before installing the new mount.
7. 7

   Position new rear engine mount
   Position the new rear engine mount between the engine block and transmission crossmember. Align the mount with the bolt holes on both the engine block and the crossmember. You may need to slightly adjust the jack height to align the holes properly.
8. 8

   Install engine-to-mount bolts
   Install the bolts securing the rear engine mount to the engine block. Thread all bolts by hand first to ensure proper alignment. Once all bolts are started, tighten them to the specified torque in a cross-pattern sequence.
   Torque spec

   Engine Mount-to-Block Bolts65 Nm (48 lb-ft)
9. 9

   Lower engine onto mount
   Carefully lower the floor jack supporting the engine, allowing the engine weight to settle onto the new rear mount. Lower slowly and watch for proper seating of the mount. Once the engine weight is fully on the mount, remove the jack from under the oil pan.
10. 10

    Install mount-to-frame bolts
    Install the bolts securing the rear engine mount bracket to the transmission crossmember. Thread bolts by hand first, then tighten to the specified torque value using a torque wrench.

11. 11

    Verify mount installation
    Visually inspect all fasteners to ensure they are fully tightened and properly seated. Check that the mount is seated correctly against both the engine block and crossmember with no gaps or misalignment. Gently rock the engine by hand to verify the mount is secure.

Reassembly

1. Reinstall the front skid plate or lower belly pan if equipped
2. Reconnect the negative battery cable
3. Lower the vehicle from jack stands

Verification

• Start the engine and observe the rear mount area for excessive movement or vibration
• With the engine running, shift the transmission through all gears (foot on brake) and verify no abnormal engine movement occurs
• Test drive the vehicle and listen for any unusual noises or vibrations during acceleration and deceleration
• Perform a final visual inspection under the vehicle after the test drive to ensure all fasteners remain tight and the mount shows no signs of movement or damage
