2012 Holden Barina engine-mount: what it does and when to replace it

Engine-mounts are absolutely fitted to the 2012 Holden Barina (TM series, T300 platform). Technical sources including the Holden Barina TM Workshop Manual and GM Global Service Information for the T300 Sonic/Aveo detail a multi-mount arrangement: an upper right engine mount, an upper left transmission mount, and front/rear torque mounts to control roll. The Holden/GM parts catalogues for TM also list these mounts as serviceable components, confirming their relevance on this model.

On the 2012 Barina, engine-mounts secure the engine and transmission to the body, isolating vibration so the cabin stays calm while also keeping the driveline aligned under acceleration, braking and cornering. Without healthy mounts, the car can feel rough, clunky, and noisy, and ancillary parts like hoses, exhaust flex joints and shafts can suffer.

Servicing is condition-based rather than kilometre-based. During routine services, a quick visual and functional check pays off. Technicians look for cracks in the rubber, split or collapsed bushings, and on fluid-filled (hydraulic) types, tell-tale oil seepage. Excessive engine movement when shifting from Park to Drive (auto) or when blipping the throttle (manual or auto) can also point to a tired mount.

• Common symptoms on a Barina when a mount is worn:
  • More vibration felt at idle or through the steering wheel
  • Clunk or thud on take-off, gear changes or lift-off
  • Visible sag in the engine position or contact between components

Replacement on a Barina TM is straightforward for a trained tech: support the powertrain from beneath, replace one mount at a time, and torque fasteners with the vehicle at normal ride height so the rubber isn’t preloaded. Upper side mounts are typically a 1–2 hour job each, the lower torque mounts are often quicker. Using quality OEM or reputable aftermarket parts keeps NVH in check. If one mount has obviously failed, it’s wise to assess the others, as extra movement can accelerate wear across the set.

Owners in Australia and New Zealand will often notice mounts age faster with heat, stop-start use, and rough roads. A quick check every service and prompt replacement when symptoms show will help the Barina feel tight, quiet and happy under the bonnet.

Popular questions about 2012 Holden Barina engine-mounts

How many engine-mounts does a 2012 Barina have?
The TM Barina typically uses four: an upper right engine mount, an upper left transmission mount, and two lower torque/roll control mounts (front and rear). This setup stabilises the powertrain and keeps vibration out of the cabin.

What are the signs an engine-mount needs replacing?
Extra vibration at idle, a thud on take-off or during shifts, and visible cracking or fluid leakage on the mount. If the engine rocks noticeably when the throttle is blipped in Neutral or when selecting Drive/Reverse, a mount may be worn.

Is it safe to keep driving with a failed mount?
Short distances may be possible, but it’s not ideal. Excess movement can stress exhaust components, hoses and driveshafts, and it can worsen other NVH issues. It’s best to book a replacement promptly to avoid knock-on damage.
