Symptoms

• Engine Vibration – The most common symptom of a bad motor mount on Hyundai vehicles is excessive engine vibrations. Excessive cabin vibrations can be noticed when stopped at a light. Typically you will feel vibrations through the car seat, on your steering wheel, and inside the cabin. Constant vibrations are felt inside the cabin when driving on the highway at 60 or 70 mph.
• Excessive Engine Movement – Worn Hyundai engine mounts allow the engine to move or shake more than designed. You will notice this most when you change gears, as a worn engine mount will cause the car to feel a bang/hit when the gears are changed.
• Engine Misalignment – The engine may be lower on the side of the failed engine mount.
• Broken Belts and Hoses – Due to the engine lowering or moving, you may have problems with A/C lines or other hoses breaking too frequently.

Procedure

1. Remove engine under shield. Support the engine from underneath. To do so, first, remove the plastic cover located under the engine. It is not necessary to jack up the car, but it may do so if you find that more practical. This is a picture of an undercover located right below the engine. It is also called the lower splash guard. It is held in place with several 10 mm bolts.
2. Once bolts have been removed, the cover can be lowered and removed.

3. Support engine. Use a floor jack to support the vehicle. If you have a small jack, don’t place it directly under the oil pan or the engine but use a wood block to place it between the jack and the engine. Be careful with this step because you can easily damage the lower part of the engine. As you see in the following picture, we used a Powerbuilt Heavy Duty Triple lift which was perfect for this task. 

4. Remove motor mount. Remove the bolts that secure the motor mount to the engine. Next, remove bolts that hold the motor mount to your car frame. If the engine starts to lower as you loosen the motor mount to engine bolts,  raise the engine using the jack underneath slightly. Otherwise, you risk putting too much stress on the engine hoses and lines, making them break.

5. Replace Hyundai motor mount. Install the engine mount. Make sure that the holes on the motor mount align with the bolt holes on the engine and the car frame. If they don’t, you may need to jack up or lower the engine until you can see the holes. Start threading the bolts by hand. Be careful tightening the bolts to the engine. Do not over-tighten these bolts, or you risk stripping the threads. Tighten the bolts to recommended torque specifications.

Frequently Asked Questions

Can I replace the motor mount on a Hyundai myself?

Yes. Replacing the motor mount on Hyundai vehicles is easy and can be completed at home. You don’t need a lift to replace an engine/motor mount.

How do I check if the motor mount on my Hyundai is bad?

You will typically know because your car will have constant vibration. The vibrations will be felt on your seat, steering wheel, and cabin. Vibrations are felt the most when the car is parked, in drive, or at a stop light.

The car lurches or bangs into gear; can it be a bad motor mount?

Yes, it is possible that a bad motor mount can cause you to think that the transmission is not shifting smoothly. That’s because once the motor mount wears or fails, it will allow the engine to move excessively when the transmission shifts gears.

Do I need to support the engine to change the motor mounts on my Hyundai?

You should always support the engine to relieve pressure from the hoses, wires, and the other two motor mounts. You don’t need to raise the engine more than half an inch.
