1998 Mitsubishi Pajero Timing-Belt Kit — What It Is, When To Replace, And Why It Matters

Drawing on technical references including the Mitsubishi Pajero factory workshop manuals (V2–V6/V20 series, 1991–1999), Gates and Dayco AU/NZ application catalogues, and Autodata service schedules: a timing-belt-kit is relevant for many 1998 Mitsubishi Pajero variants. The petrol 3.0L V6 (6G72), petrol 3.5L V6 (6G74), and 2.5L turbo‑diesel (4D56) use a toothed timing belt, for which full belt kits are specified. The 2.8L turbo‑diesel (4M40) uses a timing chain and therefore does not require a timing-belt-kit.

For 1998 Pajeros fitted with a belt, the timing-belt-kit is the sensible, all‑in‑one way to keep the engine’s valve timing spot‑on and avoid nasty surprises. The belt synchronises the crank and cams so the engine breathes when it should, the kit bundles the belt with the correct tensioner, idler pulleys and, on many setups, the water pump and seals. That means fewer trips under the bonnet and peace of mind on the open road.

Recommended replacement intervals, per AU/NZ guides and workshop data, are typically every 90,000–100,000 kilometres or 5 years (whichever comes first). If the vehicle tows, sees lots of stop‑start work, or spends time in dusty outback conditions, bringing that forward is smart. A fresh belt with new tensioners and idlers keeps everything running quietly and reduces the risk of slippage. On many Pajero V6 and 4D56 applications, doing the water pump at the same time saves labour and prevents having to pull it all apart again later.

Plenty of Pajero engines of this era are considered interference designs, so a failed or jumped belt can lead to valve and piston contact — the sort of drama no one wants on a weekend away. That’s why quality parts and correct torque procedures matter. A good kit will include:

• Timing belt to suit the specific engine code
• Hydraulic or mechanical tensioner and idler pulleys
• Water pump and gasket (where specified)
• Camshaft and crankshaft seals

Owners should look out for chirps, squeaks, coolant weep from the pump, or timing cover oil leaks — all hints it’s time. Have a trusted technician verify engine code (6G72, 6G74, 4D56 or 4M40) before ordering, then fit, tension, and bleed coolant per the Mitsubishi manual. Do that, and the 1998 Pajero will keep tackling Kiwi hills and Aussie highways without breaking a sweat.

FAQs

How often should the timing belt be replaced on a 1998 Pajero?
Most AU/NZ schedules and belt manufacturers recommend every 90,000–100,000 km or 5 years. If the vehicle tows, works hard, or lives in dusty conditions, consider shorter intervals. Always confirm against the engine code and service history.

What comes in a typical timing-belt-kit for this model?
Common kits include the timing belt, tensioner (hydraulic or mechanical), idler pulleys, and often the water pump plus gaskets and cam/crank seals. The exact contents depend on whether it’s a 6G72, 6G74 or 4D56. The 4M40 2.8D runs a timing chain, so a belt kit isn’t applicable.

What happens if the timing belt breaks on the Pajero V6?
Many V6 setups of this era are interference designs. A broken belt can cause valves to meet pistons, leading to costly cylinder‑head repairs. Replacing the belt and hardware on time is far cheaper than engine work after a failure.
