Parts for your 2002 Daihatsu Gran move-Drive belt

2002 Daihatsu Gran Move drive belt — what it does and when to replace it

A drive belt is absolutely relevant and fitted to the 2002 Daihatsu Gran Move. Technical references such as the Daihatsu Gran Move/Pyzar workshop manual for the HC/HD-series petrol engines, along with major belt catalogues from Gates and Dayco, list accessory (auxiliary) drive belts for this model. Those belts run key bolt-ons like the alternator, power steering pump (if fitted), and the air-con compressor. On these engines the water pump is driven by the timing belt, not the accessory belt, which is worth keeping in mind when fault-finding.

The drive belt’s job is straightforward: it transfers crankshaft rotation to the accessories so the battery charges, the steering stays light, and the cabin stays cool. When the belt wears, stretches or cracks, you’ll often hear a chirp or squeal on cold start, notice dim headlights at idle, or feel heavier steering effort. Left too long, a slipping belt can cook itself and strand the car with a flat battery.

Good servicing habits go a long way. A sensible schedule in Australia and New Zealand is to inspect the belt at every service (around every 10,000–15,000 kilometres or 6–12 months), and replace it roughly every 60,000–100,000 kilometres or 4–6 years, sooner if any wear shows. Look for glazing (shiny ribs), cracking, frayed edges, rib chunking, or contamination with coolant or oil. Spin and check the pulleys and idlers for rough bearings at the same time.

• Tension: Most Gran Moves use manual adjustment via the alternator and/or an adjuster bolt. Aim for correct spec tension from the service data, if you’re eyeballing it, a gentle 90-degree twist on the longest belt run is a rough guide. Over-tightening can kill alternator and idler bearings.
• Replacement tips: Note the routing before removal, slacken the lock and pivot bolts, move the alternator (or adjuster), slip the new belt on, set tension, then re-tighten. Start the engine and re-check tension and tracking. Re-tension after a short run-in if needed.
• Parts choice: Stick with quality belts sized for your exact setup (with/without A/C or power steering). Catalogues list different lengths and rib counts depending on trim.

If a belt snaps, the Gran Move may still run briefly, but you’ll lose charging and, if equipped, power steering assistance. Best practice is to stop and sort it rather than risk a flat battery or unsafe steering feel.

FAQs

Does the 2002 Gran Move have one serpentine belt or multiple belts?
Most examples use two ribbed accessory belts: one for the alternator and another for the A/C and/or power steering, depending on equipment. The water pump is driven by the timing belt on these engines, not the accessory belts.

How often should the drive belt be replaced?
Inspect every service and replace around 60,000–100,000 kilometres or 4–6 years. Replace sooner if there’s squeal, cracks, glazing, or contamination. After fitting a new belt, re-check tension after the first few hundred kilometres.

What belt size does my Gran Move need?
It varies by engine code and whether the vehicle has air-con and power steering. Use the VIN/engine details and a reputable parts catalogue, or match the old belt’s length and rib count if it was correct. When in doubt, a parts supplier can confirm the exact belt.
