2010 Subaru Impreza Engine Mount — What it does and when to replace it

Engine mounts are very much used on the 2010 Subaru Impreza. Technical references, including the 2010 Subaru Impreza Factory Service Manual (Engine section, “Engine Mounting”), Subaru’s Global Technical Information System (STIS), and the Subaru Genuine Parts Catalogue/FAST diagrams for the 2010 MY, all show dedicated left and right engine mounting insulators plus a transmission mount. These sources confirm the Impreza’s flat-four engine is secured to the front crossmember via rubber-insulated mounts designed to control movement and isolate vibration.

On this model, the engine mounts support the weight of the boxer engine, keep the drivetrain aligned, and soak up the twisting forces that happen under throttle, braking, and cornering. They’re built to reduce noise, vibration, and harshness (NVH) in the cabin, so the drive feels tidy and comfortable rather than buzzy or clunky. Some variants use conventional rubber mounts, while others may use fluid-filled (hydraulic) styles to sharpen refinement.

While mounts aren’t a routine “replace by kilometre” service item, they should be inspected at regular services. A good rule of thumb for the Impreza is to check them every 20,000–30,000 km during scheduled servicing. Look for cracked or perished rubber, sagging, torn bonding, or signs of fluid leakage (on hydraulic types). Also keep an eye on the mounting brackets and hardware for corrosion or looseness.

• Common symptoms of worn mounts: increased vibration at idle, a thunk or clunk on take-off or gear changes, noticeable engine rock when starting or shutting down, or exhaust contact under load.
• Replacement tips: use quality OEM or reputable aftermarket mounts, consider replacing mounts in pairs to keep balance, support the engine safely with a hoist or support bar, align studs carefully and follow the factory torque specs, after fitting, check clearances, the pitch-stop rod, grounds, and hoses, then road-test.

How long they last depends on driving style and conditions, but many Imprezas see 150,000–250,000 km before mounts show their age. Hard launches, frequent towing, or rough roads can bring that forward. For owners chasing sharper shifts and less drivetrain lash, fresh mounts can make the car feel heaps tighter under the bonnet and on the road.

Popular questions about 2010 Subaru Impreza engine mounts

How long do engine mounts last on a 2010 Impreza?
Many owners see 150,000–250,000 km, but it varies. City heat, spirited driving, and age can harden or crack the rubber sooner. Regular inspections help catch early signs before vibration creeps in.

Can worn mounts damage other parts?
Yes. Excess engine movement can stress the exhaust and catalytic converter, CV joints, shifter linkages, hoses, and wiring. Left too long, it can also make other vibrations feel worse, masking separate issues.

Are manual and auto Impreza mounts the same?
Both use two engine mounts and a transmission mount, but part numbers and stiffness can differ between manual/auto and turbo/non-turbo variants. Always match mounts to the VIN and drivetrain for the best fit and feel.
