Parts for your 2021 Mitsubishi Eclipse cross-Engine mount

2021 Mitsubishi Eclipse Cross engine mount — purpose, care, and when to replace

Engine mounts are absolutely used on the 2021 Mitsubishi Eclipse Cross (GK series). This is confirmed by technical sources including the Mitsubishi Motors Service Manual for Eclipse Cross (sections covering “Engine Mounting” with removal/installation procedures), the Mitsubishi ASA parts catalogue listings for the 2021 model year (showing right-hand engine mount, left-hand transaxle mount, and front/rear roll stopper mounts), and Mitsubishi OEM repair information on TechInfo. These sources collectively document multiple mounts that support and control the 1.5L turbo petrol engine and transaxle in this vehicle.

On this model, the engine mounts do two big jobs: they hold the engine and transaxle in the correct position, and they isolate vibration so the cabin stays quiet and comfy. Typically there’s a hydraulic mount on the engine side, a mount on the gearbox side, and a pair of torque/roll stoppers to control fore–aft movement when taking off or shifting. When these wear, drivers often notice extra vibration at idle, a thump on start-up or gear changes, or more engine movement under the bonnet.

As part of regular servicing in Australia and New Zealand, it’s smart to have the mounts visually checked at the usual service interval (often 15,000 km or 12 months, or per the owner’s handbook). A technician will look for perished rubber, collapsed mount height, cracked brackets, or hydraulic oil seepage on fluid-filled mounts. If any mount is leaking or the rubber is torn, replacement is the fix—there’s no effective repair for a failed mount.

Replacement is straightforward for a trained tech but does require safely supporting the powertrain, following factory procedures, and tightening fasteners to the specified torque with the vehicle at normal ride height. Using genuine or high-quality aftermarket parts helps maintain the intended NVH (noise, vibration, harshness) balance. After replacement, a quick road test and a re-check of fastener torque once everything has settled is good practice.

There’s no set kilometre-based replacement schedule—many mounts last well past 100,000 km, while vehicles that spend lots of time in stop–start traffic, towing, or on rough roads may wear mounts sooner. If the Eclipse Cross develops a new buzz through the steering wheel at idle, a clunk on take-off, or visible engine rock when blipping the throttle, it’s worth having the mounts inspected.

• Watch for symptoms: increased vibration, clunks, or fluid on/near a mount.
• Inspect at each service, replace any mount that’s leaking or cracked.
• Support the engine properly and follow the service manual torque specs.

How many engine mounts does a 2021 Eclipse Cross have?

Most 2021 Eclipse Cross models use four mounting points: a right-hand engine mount, a left-hand transaxle mount, plus front and rear torque (roll stopper) mounts. Exact hardware can vary slightly with 2WD vs AWD, but the layout and function are the same—support and vibration control.

What are common signs the engine mounts need attention?

Tell-tales include extra vibration at idle in Drive, a thud on start-up or when shifting, noticeable engine rock when blipping the throttle, or visible cracking and fluid seepage on a mount. If any of these pop up, a technician should inspect and confirm before other components cop the extra stress.

How long do mounts last and what might replacement cost?

There’s no fixed lifespan, but many last 100,000–200,000 km depending on driving and conditions. In Australia and New Zealand, expect labour for a single mount to be roughly 1–3 hours depending on location and access. Parts and labour together can vary widely by mount position and brand, using OEM or premium aftermarket parts helps preserve refinement.
