Parts for your 1996 Daihatsu Gran move-Drive belt pulley

1996 Daihatsu Gran Move drive-belt-pulley — purpose and servicing tips

Technical references confirm the 1996 Daihatsu Gran Move uses drive-belt pulleys. The Daihatsu service manual for the G3‑series Gran Move/Pyzar and the Daihatsu Electronic Parts Catalogue list crankshaft (harmonic balancer) pulleys, alternator pulleys, A/C compressor pulleys and idler/tensioner pulleys for the petrol engines fitted in 1996 models. Reputable aftermarket catalogues from Gates and Dayco also specify multi‑rib auxiliary belts and related pulleys for this vehicle. So yes — the drive-belt pulley is absolutely relevant on a 1996 Gran Move.

On this model, the drive-belt pulleys transfer the crankshaft’s rotation to the alternator, water pump, power steering pump and A/C compressor via V‑ribbed belts. The crank pulley (often a rubber‑damped harmonic balancer) smooths torsional vibration, keeping the accessory system running quietly and the belt tracking straight. Idler and tensioner pulleys guide the belt and set its tension — on many Gran Moves the alternator and an A/C idler provide adjustment rather than a spring‑loaded tensioner.

When it comes to maintenance, a quick look under the bonnet at each service goes a long way. Belts typically last 60,000–100,000 kilometres (or 4–6 years), but pulleys can age too. The tell‑tales owners and workshops watch for include:

• Squeal on cold start, chirping at idle, or a rhythmic whirr that changes with revs
• Visible belt glazing, cracking or frayed ribs
• Pulley wobble, misalignment or rubber delamination on the crank pulley
• Charging issues, heavy steering or A/C cutting out under load

If noise is present, the belt comes off and each pulley gets a spin test. Any roughness, play or grinding from a pulley bearing is grounds for replacement. A crank pulley showing wobble or separated rubber should be replaced promptly to avoid belt throw and vibration. It’s smart practice to replace a worn belt at the same time as a noisy pulley.

When refitting, ensure the belt routing is correct, pulley faces are clean, and alignment is true. Tension is critical: too tight and bearings suffer, too loose and the belt slips. For models with manual adjustment, set belt deflection per the workshop spec and recheck after the first few hundred kilometres. A quick re‑torque of locking fasteners and a listen for any new noises wraps up a tidy job that keeps the Gran Move charging, cooling and steering sweet as.

Popular questions about 1996 Daihatsu Gran Move drive-belt pulleys

Does the 1996 Gran Move use one serpentine belt or multiple belts?

Many 1996 Gran Move variants run two V‑ribbed belts: one for the alternator/water pump and another for the A/C (and sometimes power steering, depending on market). Each belt rides on its own set of pulleys, and tension is usually set via the alternator and an A/C idler.

How often should the drive-belt pulleys be replaced?

Pulleys don’t have a fixed interval, they’re replaced on condition. Inspect at every service and replace any pulley that’s noisy, rough, misaligned or showing rubber separation (on the crank pulley). Many owners replace suspect pulleys when doing a belt to save double labour.

What noises point to a bad pulley on a Gran Move?

A sharp chirp or squeal on start-up often hints at low belt tension or a glazed belt, while a constant rumble, grind or growl that follows engine speed usually indicates a failing pulley bearing. A visible crank pulley wobble with a thump‑thump sound suggests the harmonic balancer’s rubber has deteriorated.
