Engine mounts can fail and wear out over time. The vibration and torque from the engine transfer to the mounts and the bushings made of rubber tend to break down and fail after a considerable amount of engine use.
This applies to Mitsubishi Outlander model years: 2012, 2013, 2014, 2015, 2016, 2017, 2018, 2019, 2020, and other models such as the Outlander Sport, Mirage, Lancer, Galant, and more.
What you will need
- Place a jack with a small 2x4 piece of wood on top of it under the engine oil pan. Jack up enough to support the engine. Do not keep jacking up on the engine. The goal is to support the engine, not lift the vehicle up. Jacking up on the oil pan can bend or even crack it if too much force is applied.
- Next, with a 13mm socket and ratchet, remove the three bolts holding the motor mount to the body of the vehicle.
- Then, with a 15mm deep socket, remove the three nuts attaching the mount to the transverse engine. These can easily be removed with an impact driver.
- After removing the bolts and nuts the mount will now be able to be lifted out. Work the mount out of the vehicle being careful not to snag it on any of the wiring or air conditioning lines.
- Replace the mount with the new one. Start by tightening the three nuts snug. Then insert the bolts and tighten them down. Always remember to start the threads by hand.
- Once the fasteners are all snug the jack can be lowered and removed from under the engine.
- Lastly, torque the engine mount nuts and bolts to specification. It is important the weight of the engine is back down on the mount before torque. You are all done!
- Engine mount bolts torque: 40-50 ft-lbs
- Engine mount nuts torque: 60-75 ft-lbs
How can I tell if the engine mount on my Mitsubishi Outlander is bad?
An easy test to see if the engine mount is failing is to keep one foot on the brake and accelerate with the vehicle in reverse gear and watch the engine to see if it buckles a lot. Another sign of a failing engine is excessive clanking or banging from the engine bay, or excessive vibrations felt through the vehicle's body or steering wheel.
