Parts for your 2009 Holden Commodore-Engine mount

2009 Holden Commodore engine-mount: purpose, servicing and when to replace

The 2009 Holden Commodore (VE series) is definitely fitted with engine mounts. Technical references including the Holden VE Commodore Service Manual (Engine Mechanical, 2006–2013), GM Global Electronic Parts Catalog listings for VE “engine mount insulator” (left and right), and Australian fitment guides from major suppliers (e.g., ACDelco/GM Genuine Parts and local aftermarket catalogues) all specify dedicated engine mounts for VE V6 and V8 models. These mounts are typically hydraulic rubber units that bolt between the engine brackets and the front subframe to control movement and vibration.

On this model, the engine mount’s job is to carry the weight of the engine, keep it located under the bonnet during acceleration, braking and cornering, and soak up the harsh buzz that would otherwise end up in the cabin. The hydraulic (fluid-filled) design used on many VE variants gives better noise, vibration and harshness control than solid rubber, making the Commodore feel smoother at idle and more refined on the motorway. When the mounts tire, the car can feel rough, thumpy or a bit unsettled on take-off.

Engine mounts aren’t a “service item” with a set interval, but they do age with kilometres, heat and fluid exposure. It’s smart to have them inspected at regular services—especially from around 100,000–150,000 km or if there are driveline vibes. Oil leaks (rocker covers or power steering) can speed up rubber deterioration, so sorting leaks early helps the mounts live longer.

• Tell-tale signs: extra vibration at idle in Drive, a clunk on gear changes, excessive engine rock when you blip the throttle, or a shudder on take-off.
• Visual clues: collapsed rubber, cracked bonding, or fluid weeping from hydraulic mounts.
• Secondary symptoms: stressed exhaust flex joints or hoses due to excess engine movement.

When replacement’s due, quality matters—go for reputable OE or OE-equivalent hydraulic mounts matched to your engine (V6 or V8). It’s good practice to replace mounts in pairs to keep balance and NVH consistent. Correct torqueing is done with the engine supported and normally with vehicle weight on the wheels to avoid preload. After fitting, check exhaust alignment, cooling hoses and wiring for clearances. If the car’s used for towing or spirited driving, upgraded heavy-duty mounts may be worth a look, but expect a bit more cabin feel.

There’s no real maintenance beyond periodic inspections: keep an eye on oil leaks, listen for new knocks or vibes, and have a tech check the mounts after any suspension or subframe work. A healthy set of mounts keeps the Commodore feeling tight, quiet and confidence-inspiring.

• Popular questions about 2009 Holden Commodore engine-mount

How long do engine mounts typically last on a 2009 VE Commodore?
Service experience in Australia and New Zealand suggests many last well past 100,000 km, but usage, heat and fluid exposure matter. Lots of stop‑start, towing, or fluid leaks can shorten life. Regular inspections during scheduled servicing will catch softening or collapse before it becomes bothersome.

What are the common symptoms of a failing engine mount on a VE?
Expect increased vibration at idle (especially in Drive), a thud on take‑off or when shifting, and more engine movement when you pop the bonnet and gently raise the revs. Sometimes you’ll notice exhaust or intake components touching because the engine sits lower or leans.

Is it safe to drive with a worn or broken engine mount?
A mildly worn mount is usually a comfort issue at first, but a severely collapsed or broken mount can stress the exhaust, hoses and axles, and may affect shifting feel. Short trips to a workshop are generally fine, postponing repair long‑term isn’t a great idea.
