Parts for your 1997 Daihatsu Gran move-Drive belt tensioner

1997 Daihatsu Gran Move drive-belt tensioner

For the 1997 Daihatsu Gran Move (also known as the Pyzar in some markets), an automatic accessory drive-belt tensioner isn’t used or required. Instead, the vehicle runs individual accessory belts that are tensioned manually by moving the mounted component (such as the alternator or power steering pump) or via a simple adjustable idler for the A/C. That means there’s no separate, spring-loaded “drive-belt tensioner” unit to replace on this model.

This layout is confirmed in factory and parts literature: the Daihatsu workshop manual procedures describe loosening pivot and lock bolts on the alternator and other accessories, then adjusting belt tension by sliding the unit or winding an adjuster. The Daihatsu electronic parts listings for the Gran Move/Pyzar (G30-series, HD-E engine) catalogue belts, pulleys, brackets and an A/C idler, but do not list a standalone automatic accessory tensioner assembly. Aftermarket belt catalogues for this model likewise specify belts only, with manual tensioning methods noted where applicable.

Why doesn’t it have one? It’s a straightforward, cost-effective design common to many small ’90s Daihatsu models. Rather than a single serpentine belt with a spring tensioner, the Gran Move uses multiple belts with lock-and-adjust hardware. Once set with a spanner and tightened, the belt tension is maintained by the mounting bolts.

What to do at service time? Under the bonnet, check each accessory belt for cracking, glazing, fraying, or noisy operation on cold start. Adjust tension by loosening the relevant component’s lock bolts, setting the belt to the specified deflection (use the sticker under the bonnet or workshop data), then re-tightening. Don’t overdo it—over-tension can chew out bearings in the alternator, A/C idler or power steering pump. If the A/C belt uses an idler with an adjuster screw, ensure the pulley spins smoothly and the adjuster threads are clean and lightly lubricated before setting tension.

It’s also worth noting the timing belt on the HD‑E engine does use its own cam-belt tensioner, which is a different part entirely. Follow the factory schedule for timing belt and tensioner replacement by time and kilometres, and handle that job separately from the accessory belt checks.

Technical sources referenced:

• Daihatsu Pyzar/Gran Move Workshop Manual (G30-series, HD‑E engine): accessory belt adjustment procedures show alternator/pump pivot and lock-bolt tensioning, no automatic accessory tensioner specified.
• Daihatsu Electronic Parts Catalogue (G303/G301): lists belts, brackets and A/C idler components, no accessory drive automatic tensioner assembly listed.
• Aftermarket belt catalogues for 1997 Pyzar/Gran Move (HD‑E): belts specified, manual tension method indicated, with no accessory tensioner unit catalogued.

Popular questions

Does a 1997 Daihatsu Gran Move have a drive-belt tensioner?
No. It doesn’t run a separate, spring-loaded accessory tensioner. The alternator, power steering pump and A/C belt are tensioned manually with their lock-and-adjust hardware. The timing belt does have its own tensioner, which is a different system.

How do you tension the accessory belts on a Gran Move?
Loosen the pivot and lock bolts on the relevant component, adjust belt tension by sliding the unit or turning the A/C idler adjuster, set the correct deflection per the service data, then tighten everything back up. Recheck after a short drive as belts can settle.

What should be replaced if the belts squeal on start-up?
Usually the belt itself if it’s glazed or cracked, and then reset the tension correctly. Inspect the A/C idler pulley for roughness and check the alternator and power steering pulleys for bearing noise. There’s no separate accessory tensioner to swap on this model.
