Parts for your 2003 Mitsubishi Lancer-Engine mount

2003 Mitsubishi Lancer engine-mount: what it does and how to look after it

Yes, the 2003 Mitsubishi Lancer absolutely uses engine mounts. Technical sources including the Mitsubishi Motors 2003 Lancer (CS/CH) Workshop Manual (Engine and Transaxle Mounting section), the Mitsubishi ASA/CAPS parts catalogue, and popular repair manuals (Gregory’s and Haynes) all show multiple mounts fitted: a left-hand engine mount (timing side), a right-hand transaxle mount, plus front and rear roll stoppers. They’re core hardware on every 2003 Lancer variant sold in Australia and New Zealand.

Engine mounts secure the engine and gearbox to the body while isolating vibration. They keep driveline angles in check, tame torque reaction on take-off, and protect exhaust, hoses, and wiring from strain. In the Lancer, rubber or hydraulic insulators do the cushy work while brackets and bolts handle the heavy lifting.

Typical signs a Lancer mount’s on the way out include a shake through the cabin at idle, a thud when shifting from Park to Drive, a clunk on acceleration or backing off, or visible cracks and perishing in the rubber. Hydraulic mounts can even seep fluid. Aussie and Kiwi conditions—heat, stop–start traffic, speed humps and coarse-chip roads—tend to age mounts, often making replacement sensible somewhere between 120,000 and 200,000 kilometres, sooner if the car’s driven hard or lowered.

• Inspect mounts during regular services (every 10,000–15,000 km). Look for sagging, cracks, loose fasteners, or contact between metal parts.
• Replace one failed mount promptly, if the car has high kilometres, consider doing the opposing mount or roll stopper at the same time to keep balance.
• Always support the engine/gearbox before loosening hardware. Tighten fasteners at normal ride height to avoid preloading the rubber.
• Use quality OEM-equivalent parts and new fasteners where specified in the workshop manual. Verify torque specs and procedures in the factory manual.

A competent DIYer with an engine support bar and stands can tackle some mounts, but limited access on the trans side and subframe proximity can make it a fiddly job. After replacement, expect a crisper take-off and fewer vibes through the steering wheel and seats. If any subframe bolts were disturbed, get a professional check, otherwise, just recheck torque after a short shakedown and enjoy the smoother drive.

Popular questions

How many engine mounts does a 2003 Lancer have?
Most 2003 Lancers (CS/CH) run four: left engine mount, right transaxle mount, plus front and rear roll stoppers. Exact part numbers vary by engine and transmission, but every variant has multiple mounts as shown in the Mitsubishi workshop manual and ASA parts listings.

What does a failing engine mount feel like?
Common giveaways are increased vibration at idle, a knock when selecting Drive/Reverse, and a lurch on take-off. Under the bonnet, the engine may rock more than usual when you blip the throttle, and the rubber can look cracked or oil-soaked if a hydraulic mount leaks.

Can I drive with a worn engine mount?
You can often drive short-term, but it’s not ideal. Extra movement can stress the exhaust flex, hoses and CVs, and may accelerate wear on other mounts. It’s safer and cheaper long-term to book a replacement once symptoms show.
