Parts for your 1998 Daihatsu Gran move-Drive belt pulley

1998 Daihatsu Gran Move drive-belt pulley — what it does and when to service it

Technical sources confirm the 1998 Daihatsu Gran Move (also known as the Pyzar) is fitted with accessory drive belts and associated pulleys. The factory Workshop Manual for the Gran Move/Pyzar (Engine Mechanical section, 1997–1999) details alternator, A/C and power steering belt routing and pulley inspection, while aftermarket catalogues from Gates Australia (Micro-V and DriveAlign ranges) and Dayco list matching belts and pulleys for this model. That makes a drive-belt pulley relevant and serviceable on the 1998 Gran Move.

On this model, the drive-belt pulley system transfers the engine’s rotation to essential accessories: alternator, air conditioning compressor and, where fitted, power steering pump. The crankshaft pulley leads the show, with idler and tensioner pulleys keeping the multi-rib belt aligned and tensioned. Some variants run a single serpentine-style belt for alternator and A/C, with a separate belt for power steering. Either way, healthy pulleys mean quiet running, solid charging and chilled air on a hot arvo.

For servicing, it’s wise to treat the belt and pulleys as a team. If the belt is glazed, cracked, chirping or wandering across the ribs, the pulley faces or bearings may be the real culprit. Spin each pulley by hand with the belt off, any roughness, wobble, side play, or gritty feel is a red flag. A squeal on cold start, a rattly idle, visible rust dust around a pulley, or a belt that walks to one edge are all signs a pulley is on the way out.

Recommended practice in AU/NZ workshops is to inspect the accessory belt and pulleys at every service and plan replacement of the belt around 60,000–100,000 kilometres (or 4–6 years), replacing any noisy idler/tensioner at the same time. Don’t confuse this with the timing belt — that’s a separate, critical service item.

• Use quality pulleys and belts listed for the Gran Move/Pyzar engine code.
• Check alignment with a straightedge, misaligned brackets or bent pulleys will chew through a new belt.
• Set belt tension to spec from the workshop manual, over-tight belts hammer bearings, under-tight belts slip.
• Torque fasteners correctly and recheck after a short shakedown drive.

Look after the drive-belt pulleys on a 1998 Daihatsu Gran Move and it’ll keep charging properly, steer sweetly and blow cold air without the tell-tale squeal.

Popular questions about 1998 Daihatsu Gran Move drive-belt pulleys

How do I know which pulley is making the noise?
With the belt removed, spin each pulley by hand. A good pulley is smooth and quiet with no play, a worn one feels notchy or rough, can wobble, or makes a dry scraping sound. Use a mechanic’s stethoscope on a running engine only if you’re confident with safety around rotating parts.

Should I replace the belt when I replace a pulley?
Yes. If a pulley has failed, the belt has usually worn unevenly or been heat-soaked. Replacing them together avoids repeat labour and helps bed-in a fresh, quiet system. Many techs also swap the tensioner/idler as a pair if one is noisy.

Is there a single serpentine belt or multiple belts on the Gran Move?
Most 1998 Gran Move petrol variants run a multi-rib belt for the alternator and A/C, and some trims use a separate belt for power steering. Always check the under-bonnet routing label or the workshop manual for your specific engine and accessory layout.
