2014 Holden Commodore engine mount: purpose, checks, and replacement tips

Engine mounts are absolutely fitted to the 2014 Holden Commodore (VF). This is confirmed by the Holden VF Commodore Workshop Manual within GM’s Global Service Information, which includes specific Engine Mount Replacement procedures for the V6 and V8 variants. Major catalogues such as GM Genuine Parts/ACDelco and Australian supplier Mackay Rubber also list left and right engine mounting insulators for VF models, reinforcing that the component is relevant and serviceable on this vehicle.

On a 2014 Commodore, the engine mounts’ job is to hold the engine securely in the bay while soaking up vibration so the cabin stays calm. They also keep the driveline aligned under load, controlling engine rock when a driver takes off, shifts, or brakes. Most VF mounts are rubber, often fluid-filled (hydraulic), tuned to balance comfort and control. When they age, the rubber can crack or the fluid can leak, leading to harshness, clunks, and misalignment that can stress exhaust joints and other mounts.

They’re not a routine “replace by date” item, but they do deserve inspection during regular servicing—especially once the car passes 80,000–120,000 kilometres, or sooner if it tows, sees rough roads, or has performance mods. A tech will look for collapsed mount height, torn rubber, or oily residue from a leaking hydraulic mount, and will check for excessive engine movement when shifting between Drive and Reverse.

• Common signs they’re tired: more vibration at idle, a thunk on take-off, buzzing through the steering wheel, visible sag, or fluid weeping from the mount.
• If one side fails, it’s wise to replace mounts as a pair to keep balance and height consistent.

Replacement is a straightforward workshop job, but it does require safely supporting the engine from above or below, freeing the mount brackets, and torquing fasteners to spec once the engine is settled on its weight. Heat shields must go back exactly as found. Quality matters here—genuine or reputable aftermarket mounts will usually ride better and last longer than bargain options. After installation, a quick recheck for fastener torque and any new vibrations over the next few hundred kilometres is good practice. Left too long, a failed mount can snowball into exhaust flex damage, driveline shudder, or even contact under the bonnet during hard braking, so it’s worth sorting promptly.

Popular questions about 2014 Holden Commodore engine mounts

How long do engine mounts last on a 2014 Commodore?
With normal driving, many last 100,000–200,000 km. Heat, stop‑start traffic, towing, and spirited use can shorten that. Hydraulic mounts also age with time, so a low‑kilometre car can still need them if it’s older.

Is it safe to drive with a worn or broken engine mount?
It’ll usually still move under its own steam, but it’s not ideal. Expect extra vibration and potential damage to the exhaust, shifter linkages, or other mounts. Keep speeds down and avoid hard launches until it’s repaired.

Do both engine mounts need replacing together?
It’s recommended. Replacing in pairs helps keep engine height and alignment even, reduces the chance of a quick repeat job, and maintains the intended cabin comfort.
