Parts for your 2001 Mitsubishi Pajero-Timing belt kit

2001 Mitsubishi Pajero timing-belt-kit — does it apply, and what to know

Technical references from the Mitsubishi Pajero/Montero NM–NP Factory Service Manual (2000–2006), plus Australian/NZ parts catalogues from Gates, Dayco and Autodata, clarify how the 2001 Pajero is timed. The 3.2 Di-D diesel (engine code 4M41) uses a timing chain, not a belt, so a timing-belt-kit isn’t relevant for that engine. The 3.5-litre V6 petrol (engine code 6G74) is belt-driven and does use a timing-belt-kit. Some markets also saw a 3.0 V6 (6G72), which is belt-driven as well.

• If it’s a 3.2 Di-D (4M41): timing-belt-kit not used — it has a timing chain designed for long service life, relying on good oil quality and tensioner health rather than periodic belt replacement.
• If it’s a 3.5 V6 petrol (6G74): timing-belt-kit is used — routine replacement is required.

Why no belt on the diesel? Chain drive suits the 4M41’s torque characteristics and duty cycle. With proper oil changes and a healthy chain tensioner/guide setup, there’s no scheduled belt service. If rattle on start-up or chain stretch symptoms appear, that’s a separate chain service job, not a belt kit.

For Pajeros running the 3.5 V6 petrol, the timing-belt-kit keeps the cams and crank in perfect sync, so it’s a vital bit of kit for smooth running and decent fuel economy. A proper kit typically bundles the belt, tensioner (hydraulic or mechanical as specified), idler pulleys and, in many Aussie and Kiwi kits, a water pump. Swapping the water pump while the belt’s off saves paying for the same labour twice down the track. Because the 6G74 is an interference engine, letting the belt fail can bend valves and turn a simple service into a costly top-end rebuild — not the sort of bush adventure anyone wants.

As a rule of thumb for AU/NZ conditions, owners usually plan belt replacement around 100,000 km or 5 years, whichever comes first. If the vehicle tows, hits a lot of dust, or sees hot outback runs, earlier is smart. Between changes, keep an eye on oil leaks from cam or crank seals (oil degrades belts), coolant weeps from the pump, and any chirps or timing jitters. Often, though, belts give little warning before letting go, which is why time-and-kilometre intervals matter more than waiting for symptoms.

Good practice at service time includes: fitting a quality branded kit, replacing the water pump, tensioner and idlers together, checking cam/crank seals, renewing coolant, and correctly setting timing marks and tension. A tidy job with documented intervals protects the engine and resale value, and means the Paj is ready for the next long haul.

• How often should the timing belt be changed on a 2001 Pajero 3.5 V6 in Australia or New Zealand?

Most reputable schedules and catalogues list around 100,000 km or 5 years, whichever comes first, for the 6G74 V6. If the vehicle tows, does heavy off-road work, or sees high heat and dust, shorten the interval. Always confirm with the owner’s handbook or a trusted workshop using local service data.

• Does the 2001 Pajero 3.2 Di-D have a timing belt?

No. The 3.2 Di-D (4M41) runs a timing chain, so a timing-belt-kit doesn’t apply. Keep on top of oil quality and listen for unusual chain rattle, if issues arise, that’s a separate chain, guides and tensioner assessment.

• What’s usually included in a timing-belt-kit for the 2001 Pajero 3.5 V6?

Common AU/NZ kits bundle the timing belt, tensioner assembly and idler pulleys, many also include the water pump. It’s wise to replace all those items at the same time, and consider fresh cam/crank seals and coolant while everything’s accessible.
