1997 Mitsubishi Pajero Drive-Belt — What It Does and When to Replace It

For a 1997 Mitsubishi Pajero, a drive-belt (also called accessory belt, V-belt or ribbed belt) is absolutely relevant — it’s fitted to all common engines of that year, including the 2.8L 4M40 turbo-diesel and the 3.0L/3.5L V6 petrols. Technical references such as the Mitsubishi Pajero/Montero Factory Service Manual (1991–1999 coverage), the Haynes Mitsubishi Montero/Pajero Repair Manual (1983–2000), and Australian workshop guides like Gregory’s and Max Ellery’s list drive-belt inspection and replacement as routine service items on these engines. These sources note multiple accessory belts on many variants, driving the alternator, power steering pump and A/C compressor (with the water pump typically driven by the timing system on the petrol V6s, and not by the accessory belts on the 4M40 diesel).

On a ’97 Pajero, the drive-belt’s job is to spin the essentials that keep touring smooth and reliable. No belt, no charging, heavy steering, and an A/C that goes on holiday. Many models run more than one belt, so a squeal might be one belt slipping while another still manages its job.

Good servicing here is simple and pays off. Factory literature advises regular inspections — at least every service — looking for cracking, fraying, glazing, missing ribs and contamination. Typical workshop guidance for vehicles of this era is to check tension and condition every 10,000–15,000 km or 6–12 months, and replace belts that show wear, noise or poor tensioning. On these Pajeros, belt tension is usually set with an adjuster and lock bolts rather than an automatic tensioner, so correct tension matters: too loose and it squeals and under-charges, too tight and it can eat bearings.

• Common signs it’s time: chirps or squeals on start-up, dim battery light at idle, heavy steering at low speeds, visible cracks or shiny/glazed ribs.
• Best practice: replace as a set if multiple belts run side-by-side, and re-check tension after the first few hundred kays as new belts bed in.
• Workshop tip: keep the belt routing diagram handy and note pulley condition, worn or misaligned pulleys shorten belt life.

If the vehicle has recently been off-road or through mud and water, give the belts an extra look — grit and coolant/oil splash are belt killers. With fresh, correctly tensioned belts, a 1997 Pajero stays happy, charging well and steering light, whether it’s the weekday run or a weekend track.

Popular questions about 1997 Mitsubishi Pajero drive-belts

How often should the drive-belt be replaced on a 1997 Pajero?
There isn’t a hard-and-fast kilometre figure in all cases, the manuals emphasise condition and tension. Many techs in Australia and New Zealand plan inspection every service and replacement around 60,000–100,000 km, sooner if there’s noise, wear or contamination. If one belt is failing and the vehicle uses multiple belts, it’s smart to renew them together.

Why does my Pajero’s belt squeal on cold starts?
Cold-start squeal usually points to low tension, glazing, or contamination from coolant or oil. It can also be a worn pulley or misalignment. Resetting tension on the adjuster, cleaning or replacing the belt, and checking pulley bearings typically sorts it.

Do diesel and petrol 1997 Pajeros use the same belt setup?
They both use accessory drive-belts, but routing and the number of belts differ. The 4M40 diesel commonly runs separate belts for alternator, power steering and A/C, while the V6 petrols also use multiple belts and drive the water pump via the timing belt, not the accessory belts. Always match the belt to the exact engine code.
