Parts for your 2021 Mitsubishi Asx-Engine mount

2021 Mitsubishi ASX engine mount — purpose, fitment and service tips

Yes — the 2021 Mitsubishi ASX is fitted with engine mounts. Authoritative technical sources confirm this: the Mitsubishi Motors workshop manual for ASX/RVR/Outlander Sport (MY2020–2021) contains a dedicated Engine Mounting section covering removal/installation and inspections, and the Mitsubishi ASA electronic parts catalogue lists multiple engine mounting insulators and roll-stopper assemblies for the 2021 ASX range. Common AU/NZ parts catalogues used by workshops (e.g., Mackay and major dealer EPCs) also carry direct-fit engine mounts for the 2021 model. That makes engine mounts absolutely relevant to this vehicle.

On this ASX, the mounts do the heavy lifting of holding the 2.0‑litre four-cylinder and transmission in place, isolating cabin shake and stopping the powertrain from twisting under load. Typically, there’s a main right-hand (timing-side) engine mount, a left-hand transmission mount, and front and rear torque/roll stoppers. The main upper mounts are often hydraulic to tame vibration, while the lower roll stoppers are robust rubber pieces that resist fore–aft movement when taking off, shifting or backing off.

There’s no strict replacement interval in the service schedule, but they’re wear items. In Aussie and Kiwi conditions, they’re worth a check at each major service and anytime from about 80,000–120,000 kilometres, or sooner if the vehicle tows or spends a lot of time in stop–start traffic. A technician will look for collapsed rubber, split or leaking hydraulic mounts, shiny witness marks from excessive movement, and hardware that’s stretched or corroded.

Typical signs it’s time to replace mounts include:

• Noticeable vibration at idle that improves with revs
• Clunks or thuds shifting between Drive and Reverse
• Excessive engine rock when blipping the throttle under the bonnet
• More drivetrain lash or shudder on take-off

Replacement is straightforward workshop work but needs care. The engine and transmission must be safely supported before loosening any mount hardware. It’s good practice to replace any one-time-use bolts, align the powertrain height to spec, and torque fasteners at normal ride height, following the Mitsubishi workshop manual. Quality OEM-equivalent mounts help restore refinement, mixing old and new across the set can leave residual vibration, so many techs replace mounts in pairs.

For budgeting, many ASX mounts are an hour or two each in labour depending on location and corrosion, with parts varying by brand. A quick post-fit road test and a check for exhaust or hose strain rounds out the job nicely.

Popular questions about 2021 Mitsubishi ASX engine mounts

How many engine mounts does a 2021 Mitsubishi ASX have?
Most 2021 ASX models use four mounts: a right-hand engine mount on the timing side, a left-hand transmission mount, and front and rear roll-stopper mounts. Variations by market or drivetrain are minor, but the general layout is the same.

Is it safe to keep driving with a worn engine mount?
It’ll usually still drive, but it’s not ideal. Excess movement can stress exhaust flex joints, hoses and CVT/drive shafts, and you’ll cop more vibration and clunks. It’s best to schedule replacement sooner rather than later to avoid knock-on repairs.

What symptoms point to a failed mount versus an engine tune issue?
A failed mount often shows as a thud when selecting Drive/Reverse and a shake that’s worst at idle but smooths out with revs. If the vibration follows engine speed across the rev range or comes with misfire codes, that’s more likely tune/ignition or fuel-related. A workshop can isolate this quickly with a visual check and a controlled load test.
