Parts for your 2014 Subaru Impreza-Engine mount

2014 Subaru Impreza engine mount — what it does and when to replace it

The 2014 Subaru Impreza absolutely uses engine mounts. Subaru’s factory service manual for the GP/GJ series (2012–2016) details removal and installation procedures for the engine mounting system, and Subaru’s genuine parts catalog lists left and right “engine mount insulators” for the FB20-powered Impreza models. Independent repair guides covering the same platform also show the mounts and their service steps. These technical sources confirm the part is fitted and serviceable on this vehicle.

On the 2014 Impreza, the engine mounts secure the flat-four (boxer) engine to the front crossmember while isolating vibration. They’re designed to hold the engine steady under acceleration, braking and cornering, soak up harshness, and keep noise out of the cabin. The boxer engine sits low and wide, so good mounts help the Impreza feel planted and smooth, especially with the AWD driveline transferring torque through the transmission mount as well.

There’s no fixed replacement interval for engine mounts, they’re changed on condition. Typical signs they’re tired include:

• Excess vibration at idle or when the air-con kicks in
• Clunks or a thud on take-off, shifting, or backing off
• Visible cracking, sagging rubber, or leaking (on hydraulic-style mounts)
• Excessive engine movement when blipping the throttle in neutral

As part of routine servicing, it’s smart to visually check the left and right engine mounts and the transmission mount. Look for torn rubber, separated bonding, shiny witness marks from movement, or fluid seepage if fitted with hydraulic insulators. A quick lever test (lightly, with a pry bar and the engine safely supported) can reveal excessive play. If one mount has failed, replacing mounts in pairs is often best practice to keep driveline geometry balanced.

Replacement is a straightforward but safety-critical job: the engine must be properly supported from below (or above) before removing any mount through-bolts. Torque the new hardware to the factory spec and recheck clearances to exhaust and hoses. Quality OEM or reputable aftermarket mounts will restore smoothness and protect other components like exhaust flex joints and CVT/manual driveline parts. If the Impreza has done high kilometres, refreshed mounts can make it feel noticeably tighter and quieter.

Popular questions

How long do engine mounts last on a 2014 Subaru Impreza?
Service life varies with driving conditions, heat, and kilometres. Many last well past 100,000 km, but city stop–start, oil contamination, or rough roads can shorten that. The best approach is to inspect them at regular services and replace on condition rather than by a set interval.

When symptoms like excess vibration, clunks on take-off, or a visibly collapsed mount show up, that’s the cue to replace. Leaving a failed mount can accelerate wear on exhaust components and the transmission mount.

Can worn engine mounts damage other parts?
Yes. Excess engine movement can stress exhaust flex joints, hoses and wiring, and can contribute to harshness that’s hard on the transmission mount and CV joints. It can also make the cabin noisier and less comfortable.

Sorting the mounts early keeps the driveline aligned, preserves NVH performance, and can save money on related repairs down the track.

Is it okay to drive with a bad engine mount?
It’ll usually still drive, but it’s not ideal. A failed mount can cause clunks, vibration, and extra movement that may lead to collateral damage if left too long.

If there’s a heavy thud on take-off, visible separation of the rubber, or fluid leaking from a hydraulic mount, it’s best to book it in promptly and avoid hard launches or aggressive shifting until it’s fixed.
