Parts for your 1997 Daihatsu Gran move-Drive belt pulley

1997 Daihatsu Gran Move drive-belt pulley — what it does and when to replace it

Yes, the 1997 Daihatsu Gran Move (also known as the Pyzar in some markets) uses drive-belt pulleys. This is supported by OEM workshop literature for the Gran Move/Pyzar and by major belt manufacturers’ application catalogues (Gates and Dayco) that list auxiliary/serpentine belts and associated pulleys for the alternator, power steering pump and air-conditioning compressor on this model. Autodata-style service schedules also reference auxiliary belt inspection on these vehicles, which necessarily means the pulleys are present and serviceable items.

On a Gran Move, the drive-belt pulleys transfer the engine’s crankshaft rotation to vital accessories. The crank pulley (harmonic balancer) is the driver, while the alternator, power steering and A/C pulleys are driven. Together with the V-ribbed belt(s), they keep the battery charging, the steering light, and the cabin cool. Most alternators on this era of Daihatsu use a solid pulley rather than an overrunning design, so good belt condition and clean, true-running pulleys are key to quiet operation.

For servicing, it pays to inspect the pulleys every time the belt is checked. Spin each accessible pulley by hand (engine off) and feel for roughness, sight across the pulley faces for wobble or misalignment, and look for rust dust or black rubber dust that hints at bearing wear or rib mismatch. The crank pulley’s bonded rubber layer can degrade with age—any separation, cracking or a wandering outer ring is a cue to replace it promptly.

Best-practice tips for owners and techs working on a 1997 Gran Move:

• Inspect auxiliary belts and pulleys at each service (10,000–15,000 km). Replace belts typically every 60,000–100,000 km or 5 years, sooner if noisy or cracked.
• If a belt has shredded or glazed, check every pulley for damage and alignment before refitting a new belt.
• Use the correct belt profile and length from a reputable catalogue, mismatched ribs chew out pulleys and squeal.
• Torque the crank pulley bolt to spec and never lever against pulley lips—use the proper holding tool.
• After fitting a new belt on adjustable setups, recheck tension after a few hundred kilometres as it beds in.

Popular questions

Does the 1997 Daihatsu Gran Move use one serpentine belt or multiple belts?
Most cars of this era can have one or two V‑ribbed belts, depending on equipment. Many Gran Move variants run separate belts for the alternator and for A/C or power steering. The exact setup varies by engine and market, so check the belt-routing decal under the bonnet or a parts catalogue against the vehicle’s VIN.

What noises point to a bad drive-belt pulley on a Gran Move?
A sharp chirp on cold starts often hints at belt slip or a glazed pulley. A steady squeal can be misalignment or a loose belt. A grinding or rumbling that changes with revs usually means a pulley bearing is on the way out. If you can see the pulley wobbling, park it up and sort it before it throws the belt.

Should the harmonic balancer be replaced with the belt?
Not routinely. Replace the crank pulley (harmonic balancer) only if the rubber isolator shows cracking, the outer ring has shifted, or there’s wobble. Any of those faults can shred a new belt quickly, so it’s smart to inspect the balancer closely whenever the belt is off.
