Parts for your 2016 Subaru Forester-Engine mount

2016 Subaru Forester engine-mount: purpose, service tips, and common questions

Engine mounts are absolutely used on the 2016 Subaru Forester. The factory Subaru Service Manual for the SJ-series Forester (2014–2018) includes an Engine Mounting section detailing the left and right engine mounting insulators, brackets, and the pitch stop mount. Subaru’s official parts catalogue (FAST) likewise lists the engine mount insulators for the FB25 2.5L and FA20F 2.0XT turbo variants, along with the transmission mount. These technical sources confirm the part is fitted and serviceable on this model.

On the 2016 Forester, the engine mounts do the unglamorous but critical job of holding the flat-four boxer in place while soaking up vibration and torque. By isolating the engine from the cabin and subframe, they keep the ride smooth, protect driveline components, and help maintain alignment for things like exhaust and CVs. Many vehicles run rubber or hydraulic mounts, some Forester variants use liquid-filled (hydraulic) mounts to better cancel idle buzz and harshness.

Engine mounts aren’t a scheduled replacement item, but they should be inspected during regular servicing—particularly if the car’s done big kilometres, tows, or sees rough roads. Look for these tell-tales:

• Noticeable shake at idle in Drive, or a shudder when shifting between Reverse and Drive.
• Thumps or clunks on acceleration, lift-off, or during gear changes.
• Visible cracks, collapsed rubber, separated bonding, or shiny witness marks where components have touched.
• For hydraulic mounts, any oily residue leaking from the mount body.

When replacement’s on the cards, it pays to support the engine correctly, follow Subaru’s torque specs, and tighten with the vehicle at normal ride height so the mounts aren’t preloaded. Many techs replace the left and right engine mounts as a pair to keep balance, and will also assess the transmission mount and the pitch stop mount at the same time. Access typically involves undertray removal and carefully jacking the engine with a block under the sump, battery and airbox removal can help on some variants. Sticking with genuine or high-quality aftermarket mounts keeps NVH where Subaru intended, especially on the 2.0XT where stiffer tuning may be used. After installation, a quick road test for idle quality and take-off feel will confirm the job’s spot on.

Popular questions about 2016 Subaru Forester engine mounts

How long do engine mounts usually last on a 2016 Forester?
There’s no fixed interval, but many see 120,000–200,000 km or more, depending on use. Heat, oil exposure, and frequent stop‑start or towing can shorten their life. Regular inspections during services help catch wear before it turns into cabin vibration or driveline thumps.

What are the common symptoms of a failing engine mount?
Drivers often notice rough idle in gear, a bang or lurch when selecting Drive or Reverse, and a clunk on acceleration or lift-off. Visual checks may show torn rubber or, on hydraulic types, fluid seepage. If symptoms are new, rule out misfire or exhaust contact as well.

Should both engine mounts be replaced at the same time?
It’s good practice to replace the left and right engine mounts together. If one has collapsed, the other is usually tired, and pairing helps keep NVH balanced. It’s also smart to assess the transmission mount and pitch stop mount while you’re there.
