Parts for your 1999 Daihatsu Gran move-Drive belt

1999 Daihatsu Gran Move drive-belt — what it does and when to sort it

Yes, a drive-belt is absolutely relevant on the 1999 Daihatsu Gran Move (also known as the Pyzar, M100/M110 series). Technical sources including the Daihatsu workshop manual for the M1xx platform, Autodata service schedules, and aftermarket catalogues from Gates and Dayco all list auxiliary (accessory) belts for this model to run the alternator, power steering pump and the air‑conditioning compressor.

On this Gran Move, the drive-belt setup is there to spin the must‑have ancillaries off the crank pulley. Without it, there’s no charging, no power steering assist, and no cool air from the A/C. Most engines in this model range drive the water pump via the timing belt rather than the accessory belt, so think of the drive-belt as the backbone for electrics and comfort, not engine timing.

For day‑to‑day servicing, the belt(s) should be inspected under the bonnet at each service interval (roughly every 10,000–15,000 km). Look for cracking between ribs, frayed edges, glazing (a shiny, hard look), and any rubber dust around the pulleys. A chirp or squeal on cold start, especially with the A/C on, is a classic hint the belt is loose, worn, or a pulley is out of line. Replacement timing varies with use and climate, but a safe rule for Aussie and Kiwi conditions is every 60,000–100,000 km or 4–6 years, sooner if there’s noise or visible wear.

The Gran Move typically uses separate V‑ribbed belts for the alternator/power steering and the A/C. Tension is usually set with the alternator’s adjuster or an idler screw on the A/C belt—no auto tensioner on most variants. After fitting a new belt, recheck tension after 500–1,000 km as it beds in. While you’re there, spin the idler and tensioner pulleys by hand, any roughness or play means they’re due as well. Keep belt ribs and pulleys clean—no belt dressing sprays needed. And don’t mix this up with the cam belt, that’s a different service item with its own interval.

• Replace at the first sign of cracking, fray, glazing, or persistent squeal.
• Use quality V‑ribbed belts matched to the Gran Move’s engine/option combo (A/C, power steering).
• Set correct tension: firm, not guitar‑string tight—follow workshop specs if available.

Does the 1999 Gran Move have one serpentine belt or multiple belts?

Most are built with more than one auxiliary belt: one for alternator/power steering and a separate one for the A/C. Exact layout depends on engine and A/C fitment, which is why parts catalogues list multiple options for this model range.

How often should the drive-belt be replaced?

Inspect every service, plan replacement about 60,000–100,000 km or 4–6 years. If you hear squeals, see cracks, or notice charging or steering issues, bring it forward. Dust, heat and short trips can shorten belt life.

What causes belt squeal on a Gran Move?

Commonly a loose belt, worn ribs, or a glazed surface. It can also be a misaligned or failing pulley bearing. Set the correct tension, replace a tired belt, and fix any rough idlers—don’t just spray it and hope for the best.
