2012 Subaru Impreza Engine Mounts

Yep, the 2012 Subaru Impreza absolutely uses engine mounts. Technical references that confirm this include the Subaru Service Manual for the 2012 Impreza (STIS, Engine/EM “Engine Mounting” section) and the Subaru Electronic Parts Catalogue (Group 41: Engine Mounting). Those factory documents specify two primary engine mounts on the crossmember, a transmission mount, and a pitch stop mount (dog-bone) under the bonnet. So if the Impreza’s feeling a bit shakier than usual, the mounts are well worth a look.

On this model’s boxer engine, the mounts do a few key jobs: they isolate vibration so the cabin stays quiet, they keep the engine sitting at the correct height and angle, and they control torque reaction so the engine doesn’t rock about on take-off or when shifting. Good mounts mean smoother idle, nicer shifts, fewer rattles and less strain on exhaust, hoses and driveline bits.

There’s no fixed replacement interval for engine mounts on a 2012 Impreza, it’s condition-based. As part of regular servicing (say every 20,000–30,000 km), a quick visual and functional check is smart. Things to watch for:

• More vibration felt through the steering wheel or seats at idle or in Drive.
• Clunks or thuds on take-off, shifting or over bumps.
• Excess engine movement when blipping the throttle with the bonnet up.
• Cracked, perished or collapsed rubber on the side mounts, torn pitch stop bush, signs of fluid weep on any hydraulic-style mount.

When replacement’s due, doing both side engine mounts together is good practice, and checking the transmission mount and pitch stop at the same time saves headaches. Fit quality OEM or reputable aftermarket mounts to keep NVH in check. The job typically involves supporting the engine from above or below, loosening the subframe-side nuts, lifting the engine slightly, swapping the mounts, then torquing everything to factory spec as per the Subaru Service Manual. After fitting, a quick road test for vibration and a re-check of fasteners once the car’s heat-cycled is a tidy way to finish. Keeping these mounts in top nick helps the Impreza feel tight, well-mannered and ready for plenty more kilometres.

Popular questions about 2012 Subaru Impreza engine mounts

Does the 2012 Impreza have more than one engine mount?
Yes. It has two primary engine mounts on the front crossmember, plus a transmission mount and a pitch stop mount. Together they control engine movement and keep vibration out of the cabin.

How long do engine mounts last on a 2012 Impreza?
It varies with driving and climate, but many last 100,000–200,000 km. Lots of stop–start, heat and oil contamination will shorten their life. Inspect them during routine services and replace based on condition.

Can worn engine mounts cause other issues?
They can. Excess engine movement can stress the exhaust flex, accelerate wear in the pitch stop and transmission mount, and contribute to harsh shifts or driveline shudder. Fixing tired mounts often cleans up several symptoms at once.
