Parts for your 2012 Subaru Exiga-Engine mount

2012 Subaru Exiga engine mount: what it does and when to replace it

The 2012 Subaru Exiga definitely uses engine mounts. Subaru’s YA-series Exiga Service Manual includes an “Engine Mounting” section, and the Subaru FAST electronic parts catalogue lists left- and right-hand engine mount insulators plus a transmission mount for MY2012 Exiga variants. That makes engine mounts very much relevant on this model.

On the Exiga’s flat-four boxer engine, the engine mounts are the rubber (often hydraulic) insulators that secure the engine to the front subframe. Their job is to hold the engine in the correct position while soaking up vibration and torque movement, so the cabin stays quiet and the driveline geometry remains spot on. Healthy mounts help the Exiga feel smooth at idle, stop the engine from thumping during take-off, and keep everything aligned for tidy shifts and consistent AWD behaviour.

They’re wear items. Heat, age, oil contamination and repeated load cycles gradually soften or split the rubber. When that happens, the Exiga might show:

• Excess vibration felt through the steering wheel or seats at idle
• Clunks or shunts on start-up, gear changes or when getting on/off the throttle
• Noticeable engine movement under the bonnet when blipping the throttle
• Uneven exhaust or intake contact points from sagging

There’s no fixed kilometre interval, but many see 120,000–200,000 km before attention, depending on use. As part of routine servicing, a quick visual check for cracked rubber, collapsed mounts, separated bonding, or oil-soaked housings is smart. If the vehicle has had a rocker cover leak or power steering fluid leak, prioritise mount inspection—oils attack the rubber.

Replacement on the Exiga is straightforward for a workshop: the engine is safely supported, mount brackets are unbolted from the subframe and block, and new mounts are installed and torqued to spec before a short road test. Expect roughly 2–3 hours for a pair, varying with equipment and corrosion. Always replace in pairs where practical, and consider the transmission mount at the same time to keep NVH balanced.

Owners chasing sharper throttle feel can opt for firmer mounts, but be aware they can add cabin vibration. For daily family duties, genuine or OE-equivalent hydraulic mounts usually deliver the best comfort and longevity.

Popular questions about 2012 Subaru Exiga engine mounts

How do I tell if the engine mounts on a 2012 Exiga are worn?
Look for excess vibration at idle, clunks on take-off or shifts, and visible engine rock when you blip the throttle in Neutral with the bonnet open. A mechanic can confirm by levering the powertrain slightly and inspecting the mounts for cracks, separation or fluid leakage from hydraulic types.

How often should Exiga engine mounts be replaced?
There isn’t a set schedule. Many last well beyond 150,000 km, but high heat, stop–start city use and oil leaks can shorten life. Inspect them at every major service and replace when vibration, movement or damage is evident.

Can firmer aftermarket mounts improve the Exiga’s feel?
Yes, stiffer mounts can reduce engine movement and sharpen drivetrain response. The trade-off is more vibration and noise in the cabin. For most Kiwi and Aussie daily drivers, OE-style hydraulic mounts strike the best balance.
