Parts for your 2018 Mitsubishi Outlander-Engine mount

2018 Mitsubishi Outlander Engine Mount — Purpose, Care and Replacement

Technical sources confirm the 2018 Mitsubishi Outlander does use engine mounts. The Mitsubishi Motors Outlander Service Manual (2016–2020 series, engine/engine mounting sections) and the Mitsubishi ASA Electronic Parts Catalogue list multiple engine mounting insulators and torque/roll stoppers for petrol, diesel and PHEV variants. So an engine mount is absolutely relevant to this model.

The engine mount on a 2018 Outlander keeps the engine securely located in the bay while soaking up vibration, so the cabin stays quiet and the driveline stays aligned. Most variants use a mix of rubber and hydraulic (fluid-filled) mounts to balance comfort with control. They manage engine movement under throttle and braking, protect CV joints and exhaust flex joints, and help the gearbox and subframe live a longer, happier life. On PHEV versions, well-performing mounts also help the hybrid system feel smooth when blending power sources.

There isn’t a fixed replacement interval, but mounts are wear items. Heat, age, stop–start traffic and rough roads all take a toll. A sensible approach in Australia and New Zealand is to check mounts during routine servicing (every 10,000–15,000 km or annually). Many last 100,000–180,000 km, though high-heat or heavy towing use can shorten that.

Common signs a mount’s on the way out include:

• More vibration at idle (especially in Drive), or a buzz through the steering wheel.
• Clunk or thud on take-off, gear changes, or when shifting from Reverse to Drive.
• Excessive engine rock under the bonnet when blipping the throttle.
• Visible cracks, perished rubber, collapsed height, or oily residue from a leaking hydraulic mount.

When it’s time to replace, quality matters. Choose OEM or reputable aftermarket mounts designed for the Outlander’s specific engine and drivetrain. A good workshop will support the engine properly, swap one mount at a time, and torque fasteners with the vehicle at normal ride height so the rubber isn’t preloaded. It’s smart to inspect all mounts together, if one has failed from age, its mates may not be far behind. After installation, a quick road test for NVH and driveline feel is the go.

Helpful servicing tips:

• Inspect at each service for cracks, leaks and sagging.
• If replacing a failed mount, check the torque/roll stopper and adjacent brackets and bushes.
• Rule out other NVH sources (worn spark plugs, injector imbalance, exhaust contact, or loose undertrays) before condemning mounts.

Popular questions about 2018 Mitsubishi Outlander engine mounts

How long do engine mounts last on a 2018 Outlander?
Most owners see well over 100,000 kilometres, and many stretch to 150,000–180,000 km depending on driving conditions. Heat, frequent stop–start use, and towing can shorten lifespan. Regular visual checks during servicing help catch issues early.

What are the tell-tale signs my Outlander needs an engine mount?
Extra vibration at idle, a thud when shifting from Reverse to Drive, or a clunk on take-off are classic symptoms. Under the bonnet, look for cracked rubber, a mount sitting lower than normal, or fluid seepage from a hydraulic mount.

Is it safe to keep driving with a worn engine mount?
Short-term, the vehicle will usually still drive, but it’s not ideal. A failed mount can increase stress on the exhaust, CV joints and other mounts, and may worsen NVH. It’s best to schedule repair promptly to avoid knock-on damage and keep things smooth.
