Parts for your 2000 Daihatsu Gran move-Drive belt tensioner

2000 Daihatsu Gran Move drive-belt tensioner: is it actually a thing on this model?

Short answer: no, there isn’t a spring-loaded drive-belt tensioner on the 2000 Daihatsu Gran Move (also known as the Pyzar in some markets). Technical references including the Daihatsu Gran Move/Pyzar G3-series workshop manual (Cooling/Charging sections), the Daihatsu electronic parts catalogue for G301/G303 models (1999–2001), and common AUS/NZ belt catalogues (e.g., Gates Micro-V listings for HE/HD-series engines) all show conventional adjustable brackets and an idler, not an automatic tensioner. The accessory belts are tensioned manually via the alternator and power-steering pump adjusters, and the A/C belt typically uses a separate idler with a jackscrew. No standalone spring-loaded tensioner unit is listed for these engines.

Why didn’t Daihatsu fit a drive-belt tensioner on this one? It’s down to the period and the layout. The Gran Move runs multiple V-ribbed belts rather than a single serpentine with a self-tensioning arm. Belt tension is set with simple adjuster bolts and lock bolts on the alternator and pump brackets, while the A/C circuit relies on an adjustable idler. It’s a robust, low-cost setup that suits the compact engine bay and modest accessory load of the HE/HD-series four-cylinder engines of that era.

For owners, that means there’s no tensioner to replace. Instead, good servicing practice is to keep an eye on belt condition and tension under the bonnet:

• Inspect belts every 10,000–15,000 kilometres for cracking, glazing, fraying or squeal on start-up.
• Adjust tension using the alternator/power-steering adjuster bolts or the A/C idler jackscrew, then tighten the lock bolts to spec.
• After fitting new belts, recheck tension after a week or ~500 kilometres as fresh belts can bed in.
• Replace belts if they’re cracked, noisy, or the tension can’t be held—there’s no separate “tensioner” part to fix that.

So if a parts listing shows a “drive-belt tensioner” for a 2000 Gran Move, it’s usually a catalogue mix-up. What you’ll want are the correct belts and, if needed, the A/C idler pulley assembly or adjuster hardware.

Popular questions about 2000 Daihatsu Gran Move drive-belt tensioner

Does the 2000 Gran Move have a drive-belt tensioner?
Technically, no. It doesn’t use a spring-loaded automatic tensioner. Belt tension is set manually using the alternator and power-steering bracket adjusters, and the A/C belt uses an adjustable idler pulley.

How do you adjust the belt tension on this model?
Crack the lock bolt on the alternator or power-steering pump, turn the adjuster bolt until the belt deflection is within spec (check the workshop manual for your engine code), then tighten the lock bolt. For the A/C belt, wind the idler jackscrew to set tension and lock it down. Always recheck tension after a short run.

What should be replaced if the belt keeps squealing?
Start with fresh belts. If squeal returns or tension won’t hold, inspect the alternator and power-steer bracket hardware and the A/C idler pulley for wear or bearing noise. There’s no separate automatic tensioner to replace on this vehicle.
