Parts for your 2002 Mitsubishi Pajero-Drive belt

2002 Mitsubishi Pajero drive-belt: what it does and when to replace it

Yes, a drive belt is fitted to the 2002 Mitsubishi Pajero. Technical references including the Mitsubishi NM/NP Pajero Workshop Manual (2000–2006), Gates Australia and Dayco application guides confirm that both the 3.5‑litre 6G74 petrol and the 3.2‑litre 4M41 diesel use accessory drive belts to run the alternator, power steering pump and air‑conditioning compressor. Note: the 6G74 petrol uses a timing belt for the cams (separate from the accessory belts), while the 4M41 diesel uses a timing chain. So the “drive belt” here refers to the accessory/serpentine belts on the front of the engine.

On a 2002 Pajero, the drive belt’s job is to transfer engine rotation to key ancillaries. If it slips or fails, expect battery charging issues, heavy steering and weak A/C — not ideal out bush or on a winter morning in the South Island.

For everyday servicing, it pays to eyeball the belt under the bonnet at each oil change. EPDM belts don’t always crack visibly, so look and listen for these tells:

• Chirps or squeals on cold start, or when turning the steering at idle
• Glazing, frayed edges, missing ribs, or rubber dust around the pulleys
• Battery warning light flickering, dim lights, or intermittent A/C drive

Replacement intervals vary by use and climate. In Australian and New Zealand conditions, a sensible approach is:

• Inspect every 10,000–15,000 km or 6 months for wear and tension
• Replace at 60,000–90,000 km, or earlier if noise, wear, or slippage is noted

When fitting a new belt, it’s smart to renew the automatic tensioner and any idler pulleys if there’s play or roughness. Use quality EPDM belts sized to the specific engine (petrol vs diesel), route the belt per the under‑bonnet diagram, set the tensioner correctly, then run the engine and recheck alignment. A light mist of coolant or oil on the belt will cause slip, fix weeps at the cam covers or power‑steer lines first. For the petrol 6G74, remember the timing belt is a separate maintenance item (typically 100,000 km or 5 years), while the diesel 4M41’s timing drive is chain‑based, neither replaces the need to service the accessory belts.

Keeping the drive belt healthy is cheap insurance — it keeps charging solid, steering light and the cabin cool, whether the Pajero’s touring the Cape or towing the boat to Taupō.

Popular questions

Does a 2002 Pajero use one serpentine belt or multiple belts?
Most 2002 Pajero variants run multiple ribbed belts rather than a single long serpentine. Exact configuration depends on engine and accessory package, so always match the belt set to the VIN/engine code.

How often should the drive belt be replaced on a 2002 Pajero in AU/NZ?
Inspect every service (10,000–15,000 km) and plan replacement around 60,000–90,000 km. Heavy towing, outback dust, or lots of short trips may justify earlier changeouts.

What symptoms point to a tired belt or tensioner on a Pajero?
Cold‑start squeal, glazed ribs, flickering charge light, heavy steering at idle, or visible belt wander. If noise returns quickly after belt replacement, suspect the tensioner or an out‑of‑true pulley.
