This procedure covers the removal and replacement of the front engine mount on a 2015-2020 Ford F-150 with the 5.0L Coyote V8 engine, requiring proper support of the engine during the procedure.
Warnings
⚠️Never work under a vehicle supported only by a jack. Always use jack stands rated for the vehicle weight.
⚠️Ensure the engine is properly supported before removing mount bolts to prevent engine dropping or shifting.
⚠Allow the engine to cool completely before beginning work to avoid burn injuries.
ℹ️The front engine mount is located at the front-center of the engine block, accessible from above and below the vehicle.

Parts
- Front engine mount assembly × 1 — Use OEM specification
Preparation
- Park vehicle on a level surface and apply parking brake
- Ensure engine is completely cool to the touch
- Disconnect negative battery cable to prevent accidental starter engagement
- Raise and safely support the front of the vehicle on jack stands
- Remove engine splash shield/skid plate if equipped for access to mount from below
Procedure
- 1Position engine support jackPlace a floor jack with a wood block under the engine oil pan to support the engine weight. Raise the jack until it just contacts the pan with minimal upward pressure. The jack should support but not lift the engine at this point.⚠Use a wood block between the jack and oil pan to distribute load and prevent pan damage. Do not jack directly on the drain plug.
- 2Remove mount through-boltLocate the large through-bolt that passes horizontally through the engine mount assembly. Using a socket and ratchet, remove the through-bolt nut and withdraw the bolt completely. This bolt connects the engine bracket to the frame-mounted portion of the mount.ℹ️The through-bolt may be tight and require penetrating oil if corroded. Support the bolt as you remove the nut to prevent it from falling.
- 3Support engine weight and raise slightlySlowly raise the floor jack to lift the engine approximately 1-2 inches, just enough to relieve tension on the front mount. Monitor engine movement and ensure no hoses, wires, or components are being strained. The engine should rise evenly.⚠Lift slowly and check clearances around engine bay. Stop if any component appears to be binding or stretching.
- 4Remove engine mount-to-block boltsFrom above the engine, locate and remove the bolts securing the upper engine mount bracket to the engine block. There are typically 2-3 bolts. Use a socket with extension to access these bolts. Remove bolts completely and retain for inspection.Torque specEngine Mount-to-Block Bolts65 Nm (48 lb-ft)
- 5Remove mount-to-frame boltsWorking from underneath the vehicle, remove the bolts securing the lower mount bracket to the frame crossmember. These bolts typically thread vertically into the frame. Remove all fasteners completely.Torque specEngine Mount-to-Frame Bolts75 Nm (55 lb-ft)
- 6Remove engine mount assemblyWith all fasteners removed, carefully work the engine mount assembly out of position. It may require slight wiggling or the use of a pry bar to separate the mount from the frame and engine bracket. Remove the mount completely from the vehicle and inspect the mounting surfaces.
- 7Clean and inspect mounting surfacesUse a wire brush and brake cleaner to thoroughly clean the engine block mounting surface and frame mounting surface. Remove all dirt, rust, and old thread sealant. Inspect the engine bracket and frame for cracks, damage, or elongated bolt holes. Check that threads are clean and not damaged.ℹ️This is critical for proper mount alignment and torque retention. Damaged mounting surfaces may require repair before proceeding.
- 8Position new engine mountPosition the new front engine mount assembly into place, aligning the lower frame bracket with the frame mounting holes and the upper bracket with the engine block mounting holes. You may need to adjust the jack height slightly to align bolt holes properly.
- 9Install mount-to-frame boltsStart all mount-to-frame bolts by hand to ensure proper thread engagement. Once all bolts are started, tighten them in a crisscross pattern to the specified torque using a torque wrench.ℹ️Do not fully torque one bolt before starting the others. Even tightening prevents mount distortion.Torque specEngine Mount-to-Frame Bolts75 Nm (55 lb-ft)
- 10Install engine mount-to-block boltsInstall the upper engine mount-to-block bolts by hand first, ensuring proper thread engagement. Tighten bolts in a progressive pattern to the specified torque value.Torque specEngine Mount-to-Block Bolts65 Nm (48 lb-ft)
- 11Lower engine and install through-boltCarefully lower the floor jack to allow the engine to settle onto the new mount. Align the through-bolt holes in the engine bracket and mount assembly. Insert the through-bolt and install the nut. Tighten the through-bolt to the specified torque.ℹ️The through-bolt holes must align naturally as the engine settles. Do not force alignment as this indicates improper mount installation.
- 12Remove jack and verify installationSlowly lower and remove the floor jack from under the engine. Visually inspect all mount bolts to ensure they are properly seated and torqued. Check that the mount rubber is not twisted or binding and sits evenly in the bracket.
Reassembly
- Reinstall engine splash shield or skid plate if removed
- Lower vehicle from jack stands
- Reconnect negative battery cable
- Start engine and verify no unusual vibrations or movement
Verification
- With engine running, observe the front mount for proper engine support with no excessive movement
- Check that engine returns to center position when revved and released
- Verify no contact between engine components and frame or body
- Test drive vehicle and confirm no abnormal vibrations at idle or during acceleration
- Perform final visual inspection of all mount bolts to ensure none have backed out
