Parts for your 1997 Mitsubishi Pajero-Starter motor

1997 Mitsubishi Pajero starter motor — purpose, care, and when to replace

Yes, a starter motor absolutely is used on the 1997 Mitsubishi Pajero. Both the diesel (4M40 2.8L) and petrol (6G74 3.5L) variants run a 12‑volt, reduction‑gear starter with an integral solenoid, as documented in the Mitsubishi Pajero NH–NL workshop manual (Engine Electrical/Starter section) and widely covered in Gregory’s and Haynes manuals for Pajero/Montero models of the era. The Mitsubishi ASA parts catalogue also lists dedicated starter assemblies for these engines, confirming fitment across the 1997 range.

On this Pajero, the starter motor’s job is simple but crucial: it spins the engine fast enough for fuel and air to ignite, engaging a small pinion with the flywheel ring gear, then disengaging as soon as the engine fires. When it’s healthy, starts are crisp and drama‑free. When it’s tired, you’ll hear slow cranking, a single click from the solenoid, or even grinding if the pinion doesn’t mesh cleanly.

While there’s no fixed service interval for a starter, it pays to check a few basics during routine servicing. Clean, tight battery terminals and a solid engine earth strap make a massive difference to cranking speed. Inspect the starter’s main cable and trigger wire for corrosion, and make sure any heat shields are present and secure—diesel turbo heat can cook electrics over time.

• Common warning signs: slow crank when hot or cold, repeated clicking with no crank, intermittent no‑start that resolves after a tap on the starter, or a scraping/grinding noise during start.
• Smart checks first: load‑test the battery, confirm alternator charge, and verify the starter relay/ignition switch before condemning the motor itself.

If replacement is on the cards, choose a quality OEM or reputable reman unit that matches the engine code. On the 4M40, access typically means removing the bash plate and working from underneath, on the 6G74, access varies by market spec but is still straightforward with the right spanners. Disconnect the negative battery terminal, label the wiring, and follow the workshop manual for exact fastener torque and any spacer/heat‑shield refit. After install, check cranking current draw and listen for clean engagement with no chatter.

A well‑looked‑after Pajero starter will rack up heaps of kilometres. Keep the electrics tidy, watch for early symptoms, and it’ll keep turning over reliably from the high country to the coast.

Popular questions

Where is the starter motor on a 1997 Mitsubishi Pajero?
On most 1997 Pajeros, the starter sits low on the engine, bolted to the bellhousing where it can engage the flywheel. For the 2.8 diesel (4M40), access is usually from underneath after removing the bash plate. On the 3.5 V6 (6G74), it’s also near the bellhousing, accessed from underneath or the side depending on exhaust and skid plate layout.

How can someone tell if the starter or the battery is the problem?
If the dash lights dim heavily and the crank is slow on the first try, the battery may be weak. If there’s a single click or intermittent no‑crank with a healthy, fully charged battery and clean terminals, the starter or its relay/solenoid is suspect. A load test on the battery and a voltage‑drop test across the starter cables will quickly point to the culprit.

Can a failing starter damage the flywheel ring gear?
It can. A worn pinion or misalignment can cause repeated grinding, which chews the ring gear over time. If there’s grinding, stop cranking and sort the issue—continuing to crank can turn a simple starter swap into a gearbox‑out flywheel repair.
