Parts for your 2001 Toyota Bb-Drive belt

2001 Toyota bB drive-belt — what it does and when to replace it

Based on technical references for the NCP30/NCP31/NCP35 Toyota bB, a drive-belt is absolutely used on the 2001 model. Toyota’s 1NZ‑FE engine (fitted to most 2001 bB variants) is chain-driven for the camshafts, but it still runs an external accessory/serpentine drive-belt. The belt drives the alternator, air‑conditioning compressor and the engine’s water pump. This setup is documented in Toyota’s New Car Features (1NZ‑FE) and the bB Repair Manual belt routing/inspection sections, and is supported by parts catalogues from major belt manufacturers used in AU/NZ that list specific accessory belts for the 2001 bB. So yes, the drive-belt is relevant and fitted to this vehicle.

On a 2001 Toyota bB, the drive-belt’s job is to keep everyday essentials humming: charging the battery via the alternator, keeping the cabin cool through the A/C compressor, and circulating coolant with the water pump. If the belt slips or snaps, you can quickly end up with a flat battery, no A/C, or worse—overheating.

Most 1NZ‑FE bB models use a spring‑loaded automatic tensioner, so belt tension is set by the tensioner rather than by prying on the alternator. During routine servicing, it’s smart to inspect the belt and the tensioner together. Toyota service literature recommends regular visual checks
