Parts for your 1999 Mitsubishi Pajero-Timing belt kit

1999 Mitsubishi Pajero Timing Belt Kit — What’s Fitted and What To Service

Technical sources including the Mitsubishi Pajero/Montero factory workshop manuals for the 6G72/6G74 V6 engines, Mitsubishi engine manuals for the 4M40/4M41 diesels, plus the Gates and Dayco Australia application catalogues, confirm the lay of the land for the 1999 Pajero: petrol V6 models (3.0L 6G72 and 3.5L 6G74) use a timing belt and therefore take a timing belt kit, diesel models (2.8L 4M40 and early 3.2L 4M41) use timing chains and do not use a timing belt kit.

So, a timing-belt-kit is not relevant for 1999 Pajero diesels because the camshaft and injection pump timing are chain-driven with tensioners and guides designed for chain systems. Those engines are serviced with timing chain components rather than belts, and there’s no scheduled belt replacement on them.

For 1999 Pajero petrol V6s, a timing belt kit is absolutely the right gear. The kit’s job is to keep the crank and cams perfectly in sync so the 6G72/6G74 runs smoothly and efficiently. A proper kit typically includes the timing belt, idler pulleys, a hydraulic or mechanical tensioner, and—smart money—an engine water pump and cam/crank seals. Replacing the lot in one go saves double-up labour and helps avoid nasty surprises down the track.

Service guidance from Mitsubishi and component makers like Gates/Dayco points to replacement at roughly 90,000–100,000 km or 5 years (whichever comes first). Many Aussie and Kiwi workshops also recommend doing the water pump at the same time, since it’s driven by the belt and sits behind the same covers.

• Best practice during a belt job:
  • Renew belt, tensioner, and idlers as a set.
  • Replace the water pump and thermostat while you’re there.
  • Fit fresh cam and crank seals if there’s any hint of weeping.
• Handy signs it’s due or overdue:
  • Age or kilometres past the interval, cold-start squeaks, or visible cracking on the belt.
  • Coolant seep at the pump or a rattly tensioner on start-up.

Because the 6G72/6G74 are interference engines, a failed belt can bend valves and turn a simple service item into an engine rebuild. If in doubt, book it in—timely replacement is far cheaper than repairs. Unsure which engine you’ve got? Check the build plate or engine code to confirm whether your 1999 Pajero needs a belt kit (petrol) or chain components (diesel).

FAQs

Does a 1999 Mitsubishi Pajero have a timing belt or a chain?
It depends on the engine. Petrol V6 models (3.0L 6G72 and 3.5L 6G74) use a timing belt, diesel models (2.8L 4M40 and early 3.2L 4M41) use a timing chain. If you’re not sure, check the engine code on the build plate.

How often should the timing belt be replaced on a 1999 Pajero V6?
Plan on every 90,000–100,000 km or 5 years, whichever comes first. Most workshops in Australia and New Zealand also recommend replacing the water pump, tensioner, and idlers at the same time to keep things reliable.

What parts are usually included in a timing belt kit for the 6G72/6G74?
A good kit includes the belt, idler pulleys, and a tensioner, and many bundles add the water pump and seals. Fitting the complete kit avoids repeat labour and helps ensure the belt system stays quiet and stable between services.
