This procedure covers removal and replacement of the rear engine mount on a 2016-2024 Hyundai Tucson with the 2.5L I4 AWD engine.

Warnings

Tools required

Parts

• Rear engine mount assembly × 1 — Use OEM specification

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Place wheel chocks behind front wheels
3. Allow engine to cool completely if recently operated
4. Disconnect negative battery terminal to prevent electrical issues
5. Raise vehicle front end with floor jack and secure on jack stands at manufacturer frame points
6. Remove engine undercover or splash shield if equipped for access to mount area

Procedure

1. 1

   Install engine support
   Position engine support bar across engine bay fender edges or position transmission jack under oil pan with wooden block as protection. Raise jack or tighten support bar until engine weight is slightly lifted, taking load off the rear mount. The engine should be just barely supported, not raised significantly.
2. 2

   Access rear engine mount
   From underneath vehicle, locate the rear engine mount positioned between the engine block and rear subframe/crossmember. The mount is accessible from below and may be partially obscured by exhaust components or heat shields. Use work light for visibility.
3. 3

   Remove mount through bolt
   Locate and remove the large through bolt that passes through the center of the rear mount assembly. This bolt connects the mount bracket to the mount itself. Support the bolt as it is removed as it may be heavy. Note the orientation of any washers or spacers.

4. 4

   Remove mount-to-frame bolts
   Locate the bolts securing the lower mount bracket to the subframe or crossmember. There are typically 2-3 bolts. Remove these bolts completely while supporting the mount assembly. Keep track of bolt locations if they are different sizes.

5. 5

   Remove engine mount-to-block bolts
   From above or below depending on access, locate the bolts securing the upper mount bracket to the engine block or transmission bellhousing area. Remove these mounting bolts while ensuring the engine remains supported by the support bar or transmission jack.
   Torque spec

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

   Remove rear mount assembly
   With all bolts removed, carefully lower and remove the rear engine mount assembly from the vehicle. The mount may be stuck due to corrosion or alignment pins. Use a pry bar carefully if needed to break it free. Inspect the removed mount for damage, cracking, or separation of rubber from metal components.
7. 7

   Inspect mounting surfaces
   Clean mounting surfaces on both the engine block and subframe using a wire brush or scraper. Remove any rust, debris, or old gasket material. Check for cracks or damage to mounting points on the engine or frame. Verify alignment pins or locating features are not damaged.
8. 8

   Install new rear mount assembly
   Position the new rear engine mount assembly into place, aligning it with the mounting points on both the engine block and subframe. Ensure any alignment pins or locating features are properly seated. The mount orientation is critical - verify upper and lower positions match the old mount.
9. 9

   Install engine mount-to-block bolts
   Thread in the engine mount-to-block bolts by hand first to ensure proper thread engagement. Once all bolts are started, tighten them to specification using a torque wrench in a cross-pattern if multiple bolts are present. Do not fully tighten mount through bolt yet.

10. 10

    Install mount-to-frame bolts
    Install the lower mount bracket bolts that secure the mount to the subframe/crossmember. Start all bolts by hand, then torque to specification. Ensure the mount is properly seated against the frame before final torque.

11. 11

    Install mount through bolt
    Install the mount through bolt with any washers or spacers in their original orientation. Thread the bolt by hand through the mount assembly, then torque to specification. This bolt should be tightened last to allow the mount to settle into its natural position.

12. 12

    Remove engine support and lower vehicle
    Carefully remove the engine support bar or lower the transmission jack, allowing the engine weight to settle onto the new mount. Check that the engine sits level and the mount is not twisted or misaligned. Reinstall engine undercover or splash shield if removed. Lower vehicle from jack stands.

Reassembly

1. Reinstall any covers, shields, or components removed for access
2. Reconnect negative battery terminal
3. Double-check all bolts are torqued to specification and no tools are left in engine bay

Verification

• Start engine and verify no abnormal vibration or movement
• Check that engine sits level and mount is not visibly deformed under load
• Test drive vehicle and verify smooth operation with no excessive engine movement during acceleration or deceleration
• Inspect mount installation from underneath after test drive to confirm all bolts remain tight and properly seated
