Parts for your 2025 Mitsubishi Eclipse cross-Engine mount

2025 Mitsubishi Eclipse Cross engine-mount: what it does and how to look after it

Engine mounts are absolutely used on the 2025 Mitsubishi Eclipse Cross. Technical references including the Mitsubishi Motors workshop manual for the GK/GL-series Eclipse Cross (carried through to MY25) and the Mitsubishi ASA/CAPS parts catalogue list multiple mounts for both the 1.5L turbo petrol and the PHEV variants: right-hand (engine-side) insulator, left-hand (transmission-side) insulator, plus front and rear roll stoppers/torque rod. These sources also include torque specs and service steps under the Engine Mounting section, confirming the part is fitted and serviceable.

On this model, the engine mounts support the engine’s weight, keep the driveline aligned, and soak up vibration so the cabin stays quiet and comfy. The main side mounts are typically hydraulic rubber units to calm out the idle buzz and CVT torque reactions, while the front and rear torque rods rein in the twist when you jump on the throttle or creep up a steep driveway. Even on the PHEV, where the petrol engine runs intermittently, the mounts are still crucial for NVH and driveline stability when the engine kicks in.

They’re not a scheduled replacement item, but they do wear. Heat, age, oil contamination and rough roads across Aus and NZ can crack the rubber or leak the fluid from a hydraulic mount. Practical servicing advice for an Eclipse Cross owner or tech:

• Inspection every 20,000 km or at regular services: look for perished rubber, collapsed height, fluid seepage, or torn torque-rod bushes.
• Road-test for symptoms: excess vibration at idle in Drive, a thump on take-off or when shifting from Reverse to Drive, or noticeable engine rocking under the bonnet.
• If one mount has failed badly, assess the others—it’s common to replace a side mount and its opposing roll stopper together to restore balance.
• Support the engine properly with a beam or jack and timber, torque fasteners at normal ride height. Follow the workshop manual torque specs and replace any specified single-use bolts.
• Choose genuine or high-quality hydraulic mounts if you value OE-level refinement, stiffer aftermarket options can increase cabin vibration.

Typical lifespan ranges widely—often 100,000–200,000 km—but short urban trips, high heat, or oil leaks can shorten that. After replacement, a quick check for exhaust flex strain and a road test for NVH is smart. PHEV owners may see slower wear, but time and ozone still age the rubber, so don’t skip inspections.

Popular questions

How long do engine mounts last on a 2025 Eclipse Cross?

Many make it 100,000–200,000 kilometres, but heat, oil contamination, and corrugated roads can shorten that. PHEV models may see less engine-on time, which can help, though rubber still ages with time.

What are the tell-tale signs an engine mount needs replacing?

Shaking at idle in Drive, a clunk when taking off or selecting gear, visible cracks or fluid leaking from a mount, and excessive engine movement under the bonnet are the big giveaways.

Is it safe to keep driving with a worn mount?

Short-term, maybe—but it’ll feel rough and can stress the exhaust flex, driveshafts, and other mounts. Getting it sorted promptly protects the CVT and keeps the cabin calm.
