Parts for your 2014 Mitsubishi Asx-Engine mount

2014 Mitsubishi ASX engine mount — what it does and when to replace it

Engine mounts are absolutely fitted and relevant on the 2014 Mitsubishi ASX. Technical references including the Mitsubishi Motors Service Manual for RVR/ASX/Outlander Sport (2011–2016) under the Engine and Transaxle Mounting section, and the Mitsubishi ASA Electronic Parts Catalogue for GA-series ASX models, list multiple powertrain mounting insulators and roll stoppers used on this vehicle. That means the ASX relies on a set of mounts to support the engine and transmission and keep vibrations in check.

On the 2014 ASX (2.0L petrol variants common in AU/NZ), there are typically three to four mounts: a right-hand engine mount, a left-hand transaxle mount, and front/rear torque mounts (often called roll stoppers). These are rubber or hydro-elastic units designed to isolate cabin vibration, maintain driveline alignment, and control engine movement under throttle and braking. The result is a smoother drive, reduced noise/harshness, and less stress on exhausts, hoses, and shafts.

Tell-tale signs of a tired mount include extra vibration at idle with the gear engaged, clunks or thuds on take-off, noticeable engine rock when shifting, and visible cracking, collapse, or fluid seepage from a fluid-filled mount. If one mount fails, the extra load can hasten wear on the others.

There’s no strict replacement interval, condition and driving style rule the roost. As a guide, have mounts inspected during routine servicing—especially past 100,000 kilometres or if you feel new vibrations. In Australian and New Zealand conditions (stop–start commuting, heat, and the odd corrugated road), genuine or high-quality aftermarket mounts are well worth it for NVH and longevity.

When replacing, support the engine/transaxle correctly, swap one mount at a time, and torque fasteners to factory specs with the vehicle at normal ride height so the rubber isn’t preloaded. Replace any one-time-use fasteners if the manual specifies it. It’s smart to check the companion mounts, exhaust flex, and driveshafts at the same time, as a failed mount can pass on bad vibes to nearby components.

• Avoid aggressive launches and fix oil leaks that can soften rubber.
• Recheck fastener torque after a short settling period.
• If you hear a new knock after suspension or engine work, get the mounts inspected.

FAQs

How many engine mounts does a 2014 Mitsubishi ASX have?
Most 2014 ASX models use four: a right-hand engine mount, a left-hand transaxle mount, plus front and rear torque (roll) mounts. Exact layout can vary slightly with transmission and driveline.

How long do engine mounts last on a 2014 ASX?
Anywhere from 100,000 to 200,000 kilometres is common, but it depends on driving conditions and style. If you notice new vibration, shudder on take-off, or clunks, have them checked sooner rather than later.

Is it safe to drive with a worn or broken engine mount?
Short, gentle trips to a workshop may be okay, but it’s not ideal. Excess movement can stress exhausts, hoses, and driveshafts, and it can affect shift quality. Avoid hard acceleration and get it sorted promptly.
