Parts for your 2019 Subaru Impreza-Engine mount

2019 Subaru Impreza engine mount — what it does and when to change it

Yes, the 2019 Subaru Impreza absolutely uses engine mounts. This is confirmed by Subaru’s factory Service Manual (Engine/Engine Mounting section), the Subaru Genuine Parts catalogue for 2019 Impreza with the FB20 engine (listing left- and right-hand mounts on the front crossmember), and multiple OEM-equivalent parts catalogues that stock replacement mounts for this model. So, it’s a relevant and serviceable part on every 2019 Impreza, whether manual or CVT.

The engine mount’s job is simple but vital: hold the flat-four engine securely to the chassis, soak up vibration, and control fore–aft movement under throttle and braking. On the 2019 Impreza, there are typically two primary side mounts and a transmission mount, some variants may also have an additional mount to limit pitching. The rubber (often hydraulic) construction isolates buzz and harshness so the cabin feels calm, while keeping the driveline aligned so shifts are smooth and exhausts and hoses aren’t stressed.

There’s no fixed replacement interval, it’s a condition-based item. However, as kilometres rack up, rubber can harden, crack, or separate, and hydraulic mounts can weep fluid. Typical clues it’s time to book it in include:

• More vibration at idle or when the air-con kicks in
• Clunks on take-off or when shifting
• Excessive engine movement when blipping the throttle
• Visible cracks, collapsed rubber, or fluid leakage from a mount

During routine servicing, a quick visual check goes a long way: look for torn rubber, shiny witness marks from movement, or leaked fluid on hydraulic mounts. If symptoms are mild, sometimes a tired mount pair is best replaced together to keep balance side-to-side. Sticking with genuine Subaru or reputable aftermarket equivalents helps preserve the Impreza’s smoothness and NVH tuning.

Replacement isn’t complex for a trained tech, but it does require safely supporting the engine, removing undertrays and brackets, and torquing hardware to Subaru specifications on reassembly. After installation, it’s smart to recheck for driveline contact under load and verify there’s no new vibration. While a wheel alignment isn’t normally required, any mount job is a good moment to listen for other age-related bush or exhaust hanger wear that might mimic mount issues.

Look after the mounts and the Impreza rewards with the quiet, planted feel Subaru designed into the SGP platform.

FAQs

How long do engine mounts last on a 2019 Impreza?

There’s no set lifespan, but many see well over 120,000 km. Driving style, heat, and road conditions matter. City heat-soak and frequent stop–start can age rubber faster than steady highway use. Inspect during major services and act on early symptoms.

What are the tell-tale signs my mounts are failing?

Think increased vibration at idle, a thump on take-off or when shifting, and more engine rock when revved in neutral. Visual signs include cracked or collapsed rubber or fluid weeping from a hydraulic mount. Any of these warrant a closer look.

Should all mounts be replaced at once?

Not always, but it’s common to replace mounts in pairs (left and right) if wear is similar, to keep NVH balanced. If only one has obviously failed, a targeted replacement may be fine—your tech can compare condition side-to-side.
