Parts for your 2000 Daihatsu Gran move-Drive belt pulley

2000 Daihatsu Gran Move drive-belt pulley — purpose, care and replacement

Technical sources confirm the 2000 Daihatsu Gran Move (also known as Pyzar, L5 series) uses a ribbed accessory drive belt and multiple pulleys. The Daihatsu L5 workshop manual (Engine Mechanical and Air Conditioning sections) shows the crankshaft pulley driving the alternator, power-steering pump and A/C compressor via a V‑ribbed belt, with an idler/tension arrangement. The Daihatsu Electronic Parts Catalogue lists the crank pulley (harmonic balancer), alternator and A/C pulleys for HC‑EJ/HD‑EP engines, and both Gates and Dayco belt catalogues specify multi‑rib belts for this model—evidence a drive-belt pulley is absolutely relevant on this vehicle.

On the Gran Move, the drive-belt pulley system transfers the engine’s rotation to keep the electrical system charging, the steering light, and the cabin cool. The crankshaft pulley—often a bonded rubber harmonic balancer—dampens vibrations while spinning the belt. Smooth idler and tensioner pulleys keep belt wrap and tension in check so there’s no slip or squeal.

As part of regular servicing, it’s smart to give the pulleys a once-over every 10,000–15,000 km, or at each oil change:

• Look and listen: under the bonnet, check for wobble, glazing, or chunked ribs on the belt, a chirp or squeal on start-up can point to a dry or misaligned pulley.
• Spin test: with the belt off, pulleys should spin smoothly and quietly with no notchiness or play.
• Alignment: sight along the pulley faces, any offset can chew a belt quickly.
• Rubber damper: on the crank pulley, inspect the rubber ring for cracking, swelling or separation.

Replacement is straightforward for most home tinkerers with basic spanners, but a workshop manual is recommended. De-tension the belt (the Gran Move typically uses manual adjustment via the alternator or an idler), note the belt routing, and remove the affected pulley. If the crank pulley is due, lock the crank securely and torque the bolt to the factory spec from the service manual. It’s good practice to fit a new belt when swapping any pulley, and to replace tired idler/tensioner units as a set. After installation, run the motor, recheck belt tracking, and recheck tension after a few hundred kilometres. Kept in shape, the Gran Move’s pulley system will run whisper-quiet and keep the electrics, steering and A/C happy across Aussie and Kiwi conditions.

Popular questions

How do you know a drive-belt pulley is failing on a Gran Move?
Common clues include a cold-start squeal, rhythmic chirp, visible pulley wobble, or a battery/steering warning light. If the crank pulley’s rubber damper is failing, the outer ring can “walk” or sit off-centre, and you might smell hot rubber from belt slip. Remove the belt and hand-spin each pulley—any roughness, grinding or play means it’s time to replace.

Should the belt and pulleys be replaced together?
Often, yes. A worn pulley can damage a new belt, and an old belt can glaze a fresh pulley. If one component has failed or the belt shows cracks, glazing or rib chunking, replace the belt and any noisy or loose idler/tensioner at the same time for reliable, quiet running.

Is the drive-belt pulley the same as the timing belt pulley?
No. The accessory drive-belt pulleys run the alternator, A/C and power steering. The timing belt pulleys and tensioner are inside the covers and control valve timing. They’re separate systems with different service procedures and intervals.
