Engine Mount - Rear

This procedure covers the removal and replacement of the rear engine mount on a 2017 Maserati Levante with 3.0L V6 Twin Turbo engine, requiring engine support and undercarriage access.

Warnings

Tools required

Parts

• Rear engine mount assembly × 1 — Use OEM specification
• Engine mount bolts (if corroded) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Allow engine and exhaust system to cool completely
3. Disconnect negative battery terminal and wait 2 minutes
4. Raise vehicle and secure on jack stands at manufacturer-specified lift points
5. Remove lower engine splash shield/undertray for access to rear mount area
6. Inspect rear mount location from underneath to identify all mounting points

Procedure

1. 1

   Install engine support
   Position engine support bar across inner fender wells or install engine hoist with load leveler. Attach support chain or strap to engine lifting eye. Apply slight upward tension to stabilize engine but do not lift engine yet. Verify support is secure and properly positioned.
2. 2

   Locate rear engine mount
   From underneath vehicle, identify the rear engine mount assembly between the transmission bell housing area and rear crossmember/subframe. Note the position of the mount through bolt, upper mount-to-block bolts, and lower mount-to-frame bolts. Photograph mounting orientation for reference during installation.
3. 3

   Remove mount through bolt
   Using appropriate socket and extension, remove the main through bolt that passes horizontally through the center of the rear mount assembly. This bolt typically secures the mount insert to the bracket. Support the bolt as it is removed to prevent it from falling. Keep hardware organized for comparison with replacement parts.

4. 4

   Support transmission weight
   Position a transmission jack or floor jack with wood block under the transmission pan to support transmission weight independently. Apply light upward pressure to take load off rear mount. Ensure jack is stable and properly centered under transmission.
5. 5

   Remove upper mount-to-block bolts
   Remove the bolts securing the upper portion of the rear mount bracket to the engine block or transmission bell housing. Typically 2-4 bolts depending on design. Use socket with extension for access. Keep bolts organized and inspect threads for damage.
   Torque spec

   Engine Mount-to-Block Bolts65 Nm (48 lb-ft)
6. 6

   Remove lower mount-to-frame bolts
   Remove the bolts securing the lower mount bracket to the rear crossmember or subframe. These bolts secure the mount to the vehicle chassis. Access may require working around exhaust components or driveshaft. Use penetrating oil if bolts are corroded.
   Torque spec

   Engine Mount-to-Frame Bolts75 Nm (55 lb-ft)
7. 7

   Remove rear engine mount assembly
   With all fasteners removed and engine/transmission properly supported, carefully remove the rear mount assembly. It may be necessary to slightly raise or lower the transmission jack to create clearance. Inspect removed mount for cracks, separation of rubber isolator, or fluid leakage if hydraulic type. Note orientation of mount components for correct installation.
8. 8

   Clean mounting surfaces
   Use wire brush and brake cleaner to thoroughly clean all mounting surfaces on engine block, transmission, and subframe where mount contacts. Remove rust, dirt, and old thread-locking compound from bolt holes. Inspect threaded holes for damage and chase threads if necessary. Clean mating surfaces are critical for proper mount function and bolt torque.

   Position new rear mount
   Compare new mount to old mount to verify correct part. Position new rear engine mount assembly in location, ensuring proper orientation matches reference photos. Align upper mounting holes with engine/transmission and lower holes with subframe. Use jack to adjust transmission height as needed for alignment.
10. 10

    Install lower mount-to-frame bolts
    Install and hand-tighten the lower mount-to-frame bolts first to stabilize the mount position. Do not fully torque at this stage. Ensure mount bracket sits flush against subframe mounting surface.

11. 11

    Install upper mount-to-block bolts
    Install and hand-tighten the upper mount-to-block or transmission bolts. Verify mount is properly positioned and all bolts thread in smoothly without cross-threading. Check that mount isolator is not twisted or misaligned.

12. 12

    Install mount through bolt
    Install the main through bolt through the center of the mount assembly. Hand-tighten bolt completely. This bolt secures the floating mount insert and is critical for proper engine isolation.
    Torque spec

    Mount Through Bolt93 Nm (68 lb-ft)
13. 13

    Torque all mount fasteners
    Using calibrated torque wrench, torque all mount fasteners in the following sequence: First torque lower mount-to-frame bolts to 75 Nm (55 lb-ft) or 64 Nm (47 lb-ft) depending on specific bolt location. Next torque upper mount-to-block bolts to 65 Nm (48 lb-ft). Finally torque the through bolt to 93 Nm (68 lb-ft). Double-check all fasteners are properly torqued.

    Remove supports and lower vehicle
    Carefully remove transmission jack. Slowly release tension on engine support bar while observing mount for proper seating. Remove engine support equipment. Reinstall lower splash shield/undertray. Lower vehicle from jack stands and remove stands.

Reassembly

1. Verify all mount fasteners are torqued to specification and no tools or parts are left in engine bay
2. Reconnect negative battery terminal
3. Start engine and observe rear mount for proper function and no excessive movement
4. Check for any unusual vibrations at idle and during light acceleration

Verification

• With engine running at idle, observe rear mount - there should be minimal engine movement and no contact between mount and frame
• Have assistant shift transmission through all gear positions while you observe mount for security and proper function
• Test drive vehicle and verify no excessive vibration, clunking noises, or drivetrain movement during acceleration and deceleration
• Perform final visual inspection underneath vehicle to confirm all bolts are tight and mount is properly seated
