Tools required

Parts

• Front engine mount assembly × 1 — Motorcraft OEM or equivalent

Preparation

1. Park vehicle on level surface and engage parking brake
2. Disconnect negative battery cable to prevent electrical issues
3. Allow engine to cool completely if recently operated
4. Raise front of vehicle and secure on jack stands rated for vehicle weight
5. Remove engine skid plate or splash shield if equipped for better access

Procedure

1. 1

   Support the engine
   Position a floor jack with a wood block under the engine oil pan to support engine weight. Raise jack until it just contacts the pan with minimal upward pressure. Alternatively, install an engine support bar across the fender rails. The engine must be supported before removing any mount bolts.
2. 2

   Locate the front engine mount
   From underneath the vehicle, identify the front engine mount located at the front center of the engine block. The mount connects the engine block to the front crossmember frame. Note the orientation and position of the mount for proper reinstallation.
3. 3

   Remove the mount through-bolt
   Using a 19mm socket, remove the through-bolt that passes horizontally through the engine mount assembly. This bolt connects the upper bracket to the lower mount. Support the bolt as you remove it to prevent it from falling.
4. 4

   Remove engine mount-to-block bolts
   Locate the bolts securing the upper engine mount bracket to the engine block. Using an 18mm socket with extension, remove the mount-to-block bolts. There are typically 3-4 bolts securing the bracket to the front of the engine block. Keep these bolts organized for reinstallation.

5. 5

   Remove engine mount-to-frame bolts
   Locate and remove the bolts securing the lower mount bracket to the front crossmember frame using an 18mm socket. These bolts thread upward into the frame. Support the mount assembly as you remove the final bolt.
   Torque spec

   Engine Mount-to-Frame Bolts75 Nm (55 lb-ft)
6. 6

   Remove old engine mount assembly
   With all fasteners removed, carefully lower and remove the engine mount assembly. You may need to slightly raise or lower the engine using the support jack to create clearance. Maneuver the mount out from between the engine and frame.
7. 7

   Inspect mounting surfaces
   Clean the engine block mounting surface and frame mounting surface with a wire brush. Remove any rust, debris, or old gasket material. Inspect the mounting holes for damage or stripped threads. Check that the frame mounting area is not cracked or damaged.
8. 8

   Position new engine mount
   Position the new front engine mount assembly between the engine and frame. Align the upper bracket with the engine block mounting holes and the lower bracket with the frame mounting holes. Adjust engine height with the support jack as needed to align all mounting points.
9. 9

   Install engine mount-to-block bolts
   Thread in the engine mount-to-block bolts by hand to ensure proper thread engagement. Once all bolts are started, tighten them in a crisscross pattern using an 18mm socket and torque wrench to specification.

10. 10

    Install engine mount-to-frame bolts
    Install the lower mount-to-frame bolts through the crossmember into the mount bracket. Thread bolts by hand first, then tighten to specification using an 18mm socket and torque wrench.

11. 11

    Install mount through-bolt
    Insert the through-bolt horizontally through the mount assembly, connecting the upper and lower brackets. Ensure the bolt passes through cleanly without cross-threading. Tighten the through-bolt to specification using a 19mm socket and torque wrench.
12. 12

    Remove engine support
    Carefully lower and remove the floor jack or engine support bar. The engine weight should now be fully supported by the new mount and other engine mounts. Observe that the engine sits level and the mount is not over-compressed or extended.
13. 13

    Reinstall shields and lower vehicle
    Reinstall the engine skid plate or splash shield if removed. Reconnect the negative battery cable. Lower the vehicle from jack stands and remove all tools from the engine bay.

Reassembly

1. Ensure all bolts are torqued to specification in the correct sequence
2. Verify engine sits level and mount is not over-compressed
3. Double-check that no tools or parts were left in the engine compartment

Verification

• Start the engine and verify no unusual vibrations or noises
• With engine running, observe the front mount for excessive movement or separation
• Perform a test drive and verify smooth acceleration with no engine movement or clunking sounds
• Re-check torque specifications on all mount bolts after initial test drive
• Visually inspect mount after 50-100 miles for any signs of loosening or failure
