Parts for your 2004 Mitsubishi Pajero-Drive belt

2004 Mitsubishi Pajero drive-belt: what it does and how to look after it

Technical sources confirm the 2004 Mitsubishi Pajero is fitted with accessory drive-belts. The Mitsubishi Pajero NM/NP Workshop Manual, along with Dayco Australia and Gates ABDS catalogues, specify belts for the alternator, power steering pump and air conditioning compressor on 2004 models. Depending on engine (3.2 Di‑D 4M41 diesel or V6 petrol), it may use a single multi‑rib serpentine belt with an automatic tensioner plus a separate A/C belt, or multiple V‑rib belts with individual adjusters.

On this Pajero, the drive-belt(s) take crankshaft rotation and run the essentials: they keep the battery charging, the steering light, and the cabin cool. If the belt slips or fails, drivers may notice a squeal on start-up, heavy steering, the battery light glowing, or the A/C dropping off. That’s why belt condition is a key part of routine servicing.

For most Aussie and Kiwi conditions, a sensible approach is to inspect the belt(s) at every service and plan replacement around 60,000–100,000 km or 4–6 years, whichever comes first. Heat, dust, off‑road water crossings and towing shorten life. Cracks across the ribs, glazing, frayed edges, missing ribs, or rubber dust around the pulleys are all red flags. If it chirps or squeals, don’t just spray it—find the cause and fix it.

Many 2004 Pajeros use an automatic tensioner for the main belt, if the tensioner’s pulley is noisy or the arm is jerky, replace it with the belt. Where a manual adjuster is fitted (often on the A/C belt), set tension to the workshop manual spec, as a rough guide, moderate thumb pressure at the belt’s longest span should only deflect a little. Over‑tightening can knock out alternator, idler and power‑steer pump bearings, too loose and it’ll slip and glaze.

• Listen for belt noise on cold start and with A/C on.
• Inspect ribs and edges under good light, rotate the crank by hand to see the whole belt.
• Spin idlers and tensioner pulleys, any grumble means replacement.
• If a belt has failed, check every pulley for alignment and bearing condition before refitting.

The short version for owners: a fresh, correctly tensioned belt keeps the Pajero happy on both the motorway and the back tracks, and it’s an easy win to prevent roadside dramas.

Popular questions about 2004 Mitsubishi Pajero drive-belt

How often should the drive-belt be replaced on a 2004 Pajero?

With regular checks each service, most belts in Australian and New Zealand conditions do well for 60,000–100,000 km or around 4–6 years. If the vehicle tows, spends time off-road, or sees lots of heat, plan on the earlier side. Replace sooner if there’s cracking, glazing, fraying, squeal, or if the tensioner/idlers are rough.

Does the 3.2 Di‑D use the same belt setup as the V6?

Not exactly. The 3.2 Di‑D (4M41) typically runs a main multi‑rib belt on an automatic tensioner and a separate A/C belt. The V6 petrol variants often follow a similar idea but part numbers, routing, and tensioner styles differ. Always match parts to the engine code and build date.

Can a worn drive-belt cause battery and steering issues?

Yes. A slipping belt can underdrive the alternator, triggering the charge light and weak battery symptoms. It can also reduce power steering pump output, making the steering feel heavier, especially at low speeds. Fix the belt condition and tension first, then reassess.
