Parts for your 2009 Subaru Impreza-Engine mount

2009 Subaru Impreza engine mount — purpose, care, and when to replace

Engine mounts are absolutely fitted to the 2009 Subaru Impreza. Subaru’s Factory Service Manual for the GE/GH/GR chassis (MY2009) includes an Engine Mounting section, and the Subaru Genuine Parts Catalogue for the same model lists left and right engine mount insulators and brackets, plus a transmission mount and pitch-stop (torque) rod. These technical sources confirm the engine mount is relevant and used on this vehicle.

On a 2009 Impreza, the engine mounts secure the flat-four under the bonnet to the front subframe, keeping the engine aligned while isolating vibration so the cabin stays calm. They also control how much the engine rocks on take-off, during gear changes, and over rough roads. Most variants use robust rubber insulators, some trims may employ fluid-filled designs for extra refinement. Either way, they’re critical for smooth drivability and protecting exhaust joints, hoses, and CVs from undue stress.

There’s no scheduled replacement interval in the service book, but mounts are wear items. Under Aussie and Kiwi conditions, many last well past 150,000 km, though city stop–start, performance driving, oil contamination, or age-related perishing can bring that forward. It’s smart to inspect them during major services, clutch work, timing belt/water pump jobs, or whenever the front subframe is loosened. Look for sagging, cracked rubber, separated bonding, or excessive engine movement when shifting from Drive to Reverse or blipping the throttle.

Replacement tips for a 2009 Impreza engine mount:

• Replace mounts in pairs (left and right) for balance, check the transmission mount and pitch-stop at the same time.
• Support the engine safely with a hoist or under-sump support pad, do not jack on the alloy sump without a spreader.
• Loosely fit all fasteners, settle the drivetrain, then torque to the factory spec from the Subaru Service Manual.
• If there’s oil on the mounts, fix the leak first—oil-soaked rubber fails early.
• Choose quality OEM or reputable aftermarket mounts that suit your model (NA vs turbo, manual vs auto).

Common signs the 2009 Impreza needs mounts include extra vibration at idle, a knock on take-off or lift-off, shudder when engaging first gear or Drive, and misaligned exhaust or radiator hoses. Sorting tired mounts restores refinement, protects surrounding components, and keeps that boxer feel tidy for the long haul.

FAQs

How long do engine mounts last on a 2009 Subaru Impreza?
Many go beyond 150,000 km, but lifespan varies with driving style, heat, and oil exposure. Regular checks during major services help catch ageing rubber before it causes vibration or clunks.

What are the symptoms of a failing engine mount on this model?
Expect increased cabin vibration at idle, thumps on take-off or when changing gears, and visible engine rock under the bonnet. You might also notice stressed exhaust joints or hoses.

Can it be driven with a worn engine mount?
Short-term, usually yes, but it’s not ideal. Prolonged driving can stress the exhaust, axles, and other mounts. Plan a repair soon to avoid knock-on damage and keep the car feeling tight.
