Parts for your 2018 Mitsubishi Outlander-Starter motor

2018 Mitsubishi Outlander starter motor: what’s fitted and what’s not

For the 2018 Mitsubishi Outlander, whether a starter motor is relevant depends on the variant. The petrol and diesel Outlander models (non-hybrid) are fitted with a conventional 12‑volt starter motor. The 2018 Outlander PHEV does not use a conventional starter motor at all—the engine is cranked by the front motor‑generator using high‑voltage power, so a traditional starter isn’t present or required.

Technical sources supporting this: Mitsubishi Outlander PHEV New Model/Technical Training and Workshop Manual (2014–2019) state the PHEV has “no conventional starter motor or alternator, the generator starts the engine under EV‑ECU/ECM control.” Conversely, the Mitsubishi Outlander (GF/ZE) Petrol/Diesel Service Manual (2016–2020) includes a full Starting System section covering the 12 V starter motor, and the Mitsubishi ASA electronic parts catalogue lists a starter motor assembly for the 2.4‑litre petrol and 2.2 Di‑D engines.

• Mitsubishi Outlander PHEV Technical Training/Workshop Manual (2014–2019): engine start by generator, no starter motor.
• Mitsubishi Outlander (GF/ZE) Petrol/Diesel Service Manual (2016–2020): Starting System with 12 V starter motor.
• Mitsubishi ASA Parts Catalogue (2018 GF series): starter motor listed for petrol/diesel, not listed for PHEV.

If your 2018 Outlander is a petrol or diesel model, here’s what the starter motor does and how to look after it. The starter motor’s job is simple but critical: it spins the engine fast enough for the ECU to add fuel and spark so the engine can fire. It draws a hefty current from the 12 V battery via the main cable and starter relay, and throws a small gear (the pinion) into the flywheel to crank the engine. Because it works hardest at cold starts and after lots of short trips, it’s sensitive to low battery voltage and poor connections.

As part of regular servicing, keep the battery healthy, clean the terminals, and check the main engine and body earth straps. If you’re hearing a single click with no crank, slow cranking, or intermittent starts, don’t assume the starter’s dead—rule out a weak battery, corroded cables, or a tired relay first. A quick voltage‑drop test across the positive cable and the earth path will often pinpoint high resistance before you spend money on a motor.

When replacement is actually needed, go for a quality OEM‑equivalent unit. Under the bonnet, disconnect the negative battery terminal first, then access the starter (usually from above and below on the 2.4 petrol and 2.2 diesel), unplug the solenoid connector, remove the main B+ nut, and take out the mounting bolts. Refit in reverse, tightening to the workshop‑manual torque specs, then reconnect the battery and confirm clean, strong cranking. It’s smart to check the flywheel teeth while you’re in there and to verify the inhibitor/park‑neutral switch operation if starting issues were intermittent. Avoid repeated long cranks—if it doesn’t start quickly, let it rest to prevent heat‑soak and protect the starter. With a good battery and tidy connections, a starter on an Outlander typically runs for years without fuss.

Popular questions about the 2018 Mitsubishi Outlander starter motor

Does the 2018 Outlander PHEV have a starter motor?
No. The PHEV variant doesn’t use a conventional 12 V starter. The petrol engine is spun by the front motor‑generator using high‑voltage power under the EV system’s control. There’s still a 12 V battery in the car, but it’s for control units and accessories, not engine cranking.

What are common signs the starter is failing on a non‑PHEV 2018 Outlander?
Typical signs include a single click with no crank, slow or laboured cranking, intermittent starts, or visible arcing at the starter cable. Always test the battery and clean the terminals first—low voltage and dodgy earths can mimic a bad starter.

How long should a starter last, and what about replacement costs in AU/NZ?
Many last well beyond 150,000 km if the battery and cables are kept in good nick. Replacement time and cost vary by engine and access, plus whether the unit is new or remanufactured. Get a proper diagnosis before replacing to avoid swapping parts unnecessarily.
