Parts for your 2013 Subaru Impreza-Engine mount

2013 Subaru Impreza engine mounts — what they do and when to replace them

Engine mounts are absolutely fitted to the 2013 Subaru Impreza. Subaru’s factory Service Manual for the GP/GJ series (2012–2016) lists the “Engine Mounting” procedure, and the Subaru EPC/FAST parts catalogue shows left and right engine mounts plus the pitching stopper (often called a pitch stop mount) for FB16/FB20 models with both manual and Lineartronic CVT. These technical sources confirm the Impreza uses two side mounts on the front crossmember and a pitch stopper linking the powertrain to the bulkhead to control fore–aft movement.

On this model, the mounts carry the weight of the flat-four engine, isolate vibration from the cabin, and keep the driveline aligned under load. The rubber insulators (some variants are fluid-filled) soak up the boxer’s natural vibes, so the car feels smooth at idle and settled on the move. The pitch stopper works with the side mounts to curb engine rock on throttle and overrun, protecting exhaust joints, hoses, and the CVT or gearbox mounts.

As part of routine servicing, engine mounts should be visually checked for perished rubber, cracks, separation from the metal plate, or excessive sag. Oil contamination from leaks can soften the rubber, so sorting any rocker cover or front seal weeps helps the mounts live longer. There’s no fixed interval, but many owners see 120,000–200,000 km before wear becomes noticeable.

• Common symptoms:
  • More vibration felt through the seat or wheel at idle
  • Clunk or thud on take-off, shifting, or when lifting off
  • Excessive engine movement, shifter shake, or knocking on the firewall

Replacement is straightforward workshop work: support the engine from above or below, remove undertrays, loosen the through-bolts, lift the engine slightly, swap the mounts, then settle the engine at ride height before torquing to Subaru specs. It’s smart to inspect the pitch stopper and transmission mount at the same time. Using genuine or high-quality aftermarket mounts maintains NVH the car was tuned for. Avoid jacking on the sump, and recheck fastener torque after a short shakedown drive.

Driving long-term with a failed mount isn’t wise. Besides extra vibration, it can stress exhaust flex joints, stretch hoses, and accelerate wear in the CVT/gearbox and axles—costly headaches that a timely mount replacement avoids.

FAQs

How long do engine mounts last on a 2013 Impreza?
Many last beyond 150,000 km, but life varies with driving style, heat, and oil exposure. Regular inspections during routine services help catch cracking or collapse early, especially on cars that tow, commute in stop–start traffic, or live in hot climates.

What are the tell-tale signs the mounts need changing?
Expect more vibration at idle, a thud on take-off or gear changes, and noticeable engine movement when blipping the throttle. If there’s an oil leak nearby, check the mounts sooner—oil-soaked rubber degrades faster.

Should both side mounts be replaced together?
It’s often recommended. Ageing tends to be similar left to right, and replacing them as a pair helps keep NVH balanced. Inspect the pitch stopper and transmission mount at the same visit and replace as needed.
