Parts for your 2012 Subaru Forester-Engine mount

2012 Subaru Forester engine-mount — purpose, servicing tips, and when to replace

Technical sources confirm the 2012 Subaru Forester is fitted with engine mounts. The Subaru Factory Service Manual for the SH-series Forester (2012) contains an Engine Mounting section showing right- and left-hand rubber mounts on the front crossmember and a torque rod/pitch stop, and the Subaru FAST electronic parts catalogue lists the corresponding engine-mount components for both FB25 (non-turbo) and EJ255 (XT) variants. General repair guides such as the Haynes/Gregory’s Forester workshop manuals for this model range also cover engine-mount inspection and replacement. So, yes—engine mounts are very much relevant on a 2012 Forester.

On this Forester, the engine mounts do the unglamorous heavy lifting: they hold the engine in place, soak up vibration, and control torque movement when taking off, shifting, or climbing hills. Good mounts keep the cabin calm at idle, protect hoses and exhaust joints from strain, and stop nasty clunks when the throttle is jabbed. They’re rubber-isolated (some with liquid or voided designs) and bolted to the front crossmember, working with the pitch stop to limit fore-aft rocking.

There’s no fixed replacement interval in Subaru schedules, but it’s smart to check them any time the bonnet’s up for major servicing—especially from about 120,000–150,000 km, or sooner if the car tows, sees corrugated roads, or has oil leaks that may soften the rubber. Tell-tale signs include extra vibration at idle in Drive, a thump when selecting gear, shudder under load, or sagging that tilts the engine slightly.

• Inspection pointers: look for cracked or oil-soaked rubber, collapsed mounts (less clearance), or shiny witness marks from excessive movement.
• Driving symptoms: harshness at idle, clunks on take-off, or exhaust contact noises.

Replacement is straightforward for a pro and very doable for an experienced home mechanic with stands and a support bar or hoist. Expect to support the engine, remove the undertray, slacken the through-bolts, raise the engine a few millimetres, and swap the mounts. It’s good practice to replace mounts in pairs, and to follow torque specs from the Subaru service manual. After installation, recheck clearances, inspect the pitch stop and transmission mount, and nip up fasteners once the car has settled from a short drive.

For longevity, fix any engine oil leaks early, avoid harsh clutch dumping on manuals, and stick with quality OEM or reputable aftermarket mounts. That keeps the Forester feeling tight and quiet, just as it should on Kiwi and Aussie roads.

Popular questions about 2012 Subaru Forester engine-mounts

How long do engine mounts typically last on a 2012 Forester?
Many last well past 150,000 km, but heat, oil exposure, towing, and rough roads can shorten that. If vibrations or clunks creep in, it’s time for an inspection rather than waiting on a set distance.

Can one mount be replaced on its own, or should they be done in pairs?
One failed mount can be changed on its own, but doing both sides together helps maintain alignment, balance stiffness left-to-right, and reduces repeat labour. Most workshops recommend replacing in pairs.

What are the main signs an engine mount has failed?
Extra vibration at idle in gear, a thump when selecting Drive/Reverse, shudder on acceleration, or new exhaust knocks are common. Visual clues include torn or collapsed rubber and oil-soaked mounts.
