Parts for your 2020 Mitsubishi Outlander-Starter motor

2020 Mitsubishi Outlander starter motor — what’s fitted and what to do about it

Whether a 2020 Mitsubishi Outlander has a starter motor depends on the variant. Technical sources show two distinct setups:

• Outlander PHEV (plug‑in hybrid): No conventional 12 V starter motor. The internal combustion engine is cranked by the high‑voltage generator motor. This is detailed in the Outlander PHEV Workshop Manual (2019–2020, GG2W/GF2W), in the Engine Starting Control description, where the generator (MG) spins the engine to start. There’s no “starter motor” listed in the hybrid’s electrical section.
• Outlander petrol/diesel (non‑hybrid): A conventional 12 V starter motor is fitted. The Mitsubishi Electronic Parts Catalogue (ASA) for 2020 ZL/ZK series lists a starter motor assembly in the Electrical (Starter) group for the 2.0/2.4 petrol and applicable diesel engines, matching what’s described in the conventional powertrain service manual.

Why the PHEV doesn’t use a starter motor: The hybrid system uses the traction battery to drive the generator motor, which cranks the engine smoothly and eliminates the need for a separate starter and ring‑gear engagement. The 12 V battery still powers control units and relays, so a weak 12 V battery can still prevent the PHEV from “readying” even though there’s no starter motor to crank.

If your 2020 Outlander is a petrol or diesel model, it does have a starter motor. Here’s what that means for servicing and reliability.

The starter motor’s job is simple: it spins the engine fast enough for it to fire, handing off once the engine catches. On the Outlander’s conventional engines, the starter sits low on the transmission bellhousing, engaging the flywheel or flexplate via a solenoid‑driven pinion.

As part of routine servicing, it’s smart to check the basics that make starters live a long life. A healthy battery and clean, tight battery terminals and earth points matter just as much as the starter itself. Under the bonnet, look for corroded cables, loose main starter terminal nuts, or oil leaks that could contaminate the motor. Listen for symptoms: a single click with no crank suggests a solenoid or low voltage issue, slow cranking points to a weak battery, poor connections, or a worn starter, a grinding noise can mean a damaged pinion or ring gear.

When replacement is needed, disconnect the negative battery terminal, then remove the starter’s main cable and signal wire before unbolting the unit. Keep any heat shields and spacers in order, refit to spec, and torque the electrical studs carefully to avoid cracking the insulator. After installation, a starter current draw and charging‑system test is good practice. Many starters last well beyond 150,000–250,000 kilometres, but heat, short‑trip driving, and tired batteries can shorten that. If in doubt, have an auto sparky load‑test the system rather than throwing parts at it.

Not sure which setup you’ve got? If it’s a PHEV, there’s no starter motor to service. If it’s a straight petrol or diesel, there is—confirm by VIN or a quick visual near the bellhousing.

Popular questions about 2020 Mitsubishi Outlander starter motors

Does the 2020 Outlander PHEV have a starter motor?
No. The PHEV starts its engine using the high‑voltage generator motor, controlled by the hybrid ECU. The 12 V battery still needs to be healthy to power up the control systems, but there’s no traditional starter to replace.

How can someone tell if the starter motor is failing on a petrol/diesel Outlander?
Tell‑tales include a single click and no crank, slow cranking even with a good battery, intermittent no‑crank when hot, or grinding noises. Always rule out battery and cable issues first, then have a current‑draw test done to confirm the starter itself.

Where is the starter motor on the 2020 Outlander petrol?
It’s mounted low on the transmission bellhousing, accessible from underneath. Expect tight access around heat shields, use axle stands or a hoist and disconnect the negative terminal before any work.
