Parts for your 2012 Mitsubishi Lancer-Starter motor

2012 Mitsubishi Lancer starter motor — what it does, how to look after it, and when to replace it

Technical sources including the Mitsubishi Motors CJ/CF Lancer Service Manual (Group 16: Starting and Charging), the Mitsubishi ASA electronic parts catalogue, and mainstream workshop data (Haynes/Autodata) all specify a 12‑volt, reduction‑gear starter motor for 2012 Lancer models with 4B10/4B11/4B12 petrol engines and the 4B11T turbo in Ralliart/Evo. So yes — a starter motor is absolutely fitted and relevant to the 2012 Mitsubishi Lancer.

The starter motor’s job is simple but critical: when the key is turned or the start button’s pressed, the solenoid shoves the pinion into the flywheel ring gear and spins the engine fast enough to fire. It draws heavy current from the battery, so clean, tight cables and a healthy earth are just as important as the motor itself. On the Lancer, it’s a compact reduction‑type unit designed to crank strongly while keeping weight and current draw sensible.

There’s no set replacement interval — starters are serviced on condition. During routine servicing it’s smart to check:

• Battery health and terminal cleanliness (slow crank is often a battery or cable issue).
• Main starter cable and earth strap for corrosion, looseness or heat damage.
• Any oil seepage near the bellhousing that could contaminate the starter.

Common clues a Lancer starter is on the way out include a single click with no crank, a laboured spin, intermittent no‑start that improves with a tap on the housing, or grinding after start. Before blaming the motor, a quick voltage‑drop test across the positive feed and earth under load will confirm whether the issue is wiring, battery, or the starter itself.

Replacement is straightforward for a competent tech: disconnect the negative battery lead, raise the car safely, unplug the solenoid connector, remove the main cable nut, then the mounting bolts, and drop the unit out. On Ralliart/Evo, intake or heat‑shield bits may need to come off first. Typical workshop time ranges from about an hour to a bit more on turbo models. Choose a genuine or quality OE‑equivalent unit, brush/solenoid contact overhauls are viable on high‑kilometre cars if the core is sound.

For longer life, keep the battery in good nick, avoid extended cranking, and sort any hot‑restart issues promptly. Treated well, a Lancer starter often sails past 150–250,000 kilometres before needing attention.

• Where is the starter motor on a 2012 Mitsubishi Lancer?
  On non‑turbo 4B10/4B11/4B12 cars, it’s mounted at the gearbox bellhousing side of the engine, accessible from underneath near the front of the block. On Ralliart/Evo (4B11T), it’s in a similar bellhousing position but space is tighter around turbo hardware, so intake pipes or heat shields may need to come off for access.
• What are the most common signs the starter is failing?
  A single click with no crank, slow cranking even with a known‑good battery, intermittent no‑start that responds to a light tap on the housing, or a grinding noise as the engine fires. Always rule out a weak battery and dodgy terminals first, as they mimic starter faults.
• Does the 2012 Lancer have stop/start that uses a special starter?
  No factory idle stop/start system was fitted to 2012 Lancer models in Australia or New Zealand. They use a conventional 12‑volt reduction‑gear starter motor.
