Parts for your 1996 Daihatsu Gran move-Drive belt tensioner

1996 Daihatsu Gran Move drive-belt tensioner: is it fitted, and what to know

For the 1996 Daihatsu Gran Move (also sold as the Pyzar), a separate, spring-loaded drive-belt tensioner isn’t used. Factory information shows the accessory belts are tensioned manually by moving the alternator and, where fitted, the power-steering pump, with air-conditioning models using an adjustable idler pulley. This layout is detailed in the Daihatsu Pyzar/Gran Move workshop manual (Engine Electrical and Air Conditioning sections), and it’s reflected in parts catalogues from Daihatsu’s EPC as well as aftermarket listings from Gates and Dayco, which specify belts and idler pulleys for this model but do not list an automatic tensioner assembly.

Why no tensioner on this model? Mid‑’90s compact Japanese cars commonly relied on simple bracket adjustments instead of spring tensioners. It keeps costs down, reduces parts count, and leaves more space under the bonnet. With fewer moving parts, there’s also less to fail. On the Gran Move, belt tension is set by loosening the pivot and lock bolts on the alternator (and power-steering pump if equipped), shifting the unit to achieve the correct belt deflection, then tightening everything back up. Air‑con versions add an idler pulley with a lock nut and adjuster screw to set tension on the A/C belt—again, no automatic tensioner in the mix.

What should an owner or tech do at service time? Rather than hunting for a non-existent tensioner, they’ll:

• Inspect belt condition for cracking, glazing, fraying, or noise, and replace if worn.
• Set belt tension by adjusting the alternator/power-steering brackets, and the A/C idler if fitted, following the factory deflection spec in the workshop manual.
• Check the idler pulley bearing (A/C models) for roughness or play and replace the pulley if needed.
• Re-check tension after a short run-in, as new belts can bed in and slacken slightly.

If someone recommends replacing a “tensioner” on a 1996 Gran Move, they’re likely referring to the A/C idler pulley or its adjuster hardware, not a true automatic tensioner. Technical references: Daihatsu Pyzar/Gran Move Workshop Manual (1996–2002), Daihatsu Electronic Parts Catalogue (E/G and A/C groups), and Gates/Dayco application data for the Gran Move/Pyzar—which list belts and idler pulleys but no automatic accessory-belt tensioner.

Popular questions

Does a 1996 Daihatsu Gran Move have an automatic drive-belt tensioner?
No. The Gran Move uses manual adjustment via the alternator and power-steering brackets, and an adjustable idler pulley for the A/C belt on equipped models. This setup is shown in the Daihatsu workshop manual and supported by parts catalogues that don’t list an automatic tensioner for this vehicle.

How do you adjust the drive belt on a 1996 Gran Move?
Loosen the alternator pivot and lock bolts, move the alternator to set the correct belt deflection, then tighten the bolts. If there’s power steering, do the same on its bracket. For A/C, loosen the idler pulley lock nut and turn the adjuster screw to tension the belt, then re-tighten. Always check the deflection spec in the workshop manual and re‑check tension after a short drive.

What parts are usually replaced instead of a “tensioner” on this model?
Common replacements are the belts themselves and, on A/C cars, the idler pulley if its bearing gets noisy or rough. Occasionally, adjuster bolts or bracket hardware are renewed if seized or worn. There’s no separate spring-loaded tensioner assembly to replace on this model year.
