Parts for your 2012 Mitsubishi Lancer-Engine mount

2012 Mitsubishi Lancer engine mounts — what they do and when to replace them

Technical sources confirm the 2012 Mitsubishi Lancer is fitted with multiple engine mounts. The Mitsubishi Lancer factory service manual for the 2008–2017 CJ/CF series includes an “Engine Mounting” section detailing inspection and replacement. The Mitsubishi ASA electronic parts catalogue lists a right-hand engine mount (timing side), a left-hand transmission mount, plus front and rear roll stopper mounts. Independent manuals, such as the Haynes Repair Manual (Lancer 2007–2017), also outline mount locations and service procedures. So yes—engine mounts are absolutely used on this model.

On a 2012 Lancer, the engine mounts support the engine and gearbox, control movement under acceleration and braking, and soak up vibration so the cabin stays smooth and quiet. When they’re healthy, the driveline stays properly aligned, shifts feel tidy, and there’s no thud on take-off or over bumps.

As part of regular servicing, it pays to give the mounts a look. A quick visual under the bonnet and from underneath can catch:

• Cracked, split, or collapsed rubber insulators
• Leaking fluid from any hydraulic-style mount
• Excessive engine movement when blipping the throttle in neutral
• Clunks on gear changes or when loading/unloading the drivetrain
• Increased vibration at idle with the air-con on

Inspection every 20,000–30,000 km (or at routine services) is a good habit. High-km cars, those driven hard, or Lancers with stiffer performance mounts (Ralliart/Evo variants) can need attention sooner. Many owners see 100,000–180,000 km from factory mounts, but usage and climate make a big difference.

When replacement’s due, best practice is to support the engine safely with a jack and timber under the sump, swap one mount at a time, and torque the hardware to the workshop manual specs with the vehicle at ride height. It’s smart to check adjacent brackets and fasteners for fatigue. If one mount has collapsed, consider replacing any others that look tired to keep the driveline balanced.

Quality matters. OEM or reputable aftermarket mounts will keep NVH in check and last longer than bargain-basement options. After fitting, expect a short bedding-in period. If vibration seems worse than before, re-check torque and alignment—many mounts must be tightened under load to avoid preloading the rubber.

Done right, fresh engine mounts make a Lancer feel tight again—clean shifts, quieter idle, and no dramas at the lights.

How can someone tell if their 2012 Lancer engine mounts need replacing?
Common signs include extra vibration at idle, a thud or knock when taking off or shifting, and noticeable engine rock when the throttle is blipped in neutral. Visual cues such as torn rubber or leaking fluid from a hydraulic mount also point to replacement. If vibration worsens with the air-con on or in Drive at a standstill, a deteriorated mount is likely.

How many engine mounts does a 2012 Lancer have and where are they?
Most 2012 Lancers use four mounts: a right-hand engine (timing-side) mount, a left-hand transmission mount, plus front and rear roll stopper mounts. The exact design varies slightly by engine and transmission, but the layout serves the same job—supporting the driveline and controlling torque movement.

Is it safe to drive with a failed engine mount?
It might be possible to drive short-term, but it’s not recommended. A failed mount can increase vibration, stress other mounts and exhaust components, and lead to harsher shifts or even contact between parts under load. Prompt replacement avoids knock-on damage and keeps the car comfortable and safe.
