Parts for your 2021 Toyota Prius-Drive belt

2021 Toyota Prius drive belt — is there one?

Short answer: no, a conventional accessory or serpentine drive belt isn’t used on the 2021 Toyota Prius (ZVW50 series, 1.8-litre 2ZR-FXE). Toyota’s hybrid layout deletes the belt altogether. Technical references that confirm this include Toyota’s New Car Features (NCF) for the ZVW50 series, the Toyota Repair Manual for the 2ZR-FXE hybrid application (which contains no drive-belt inspection/replacement procedure), and the 2021 Prius Owner’s Manual maintenance schedule (no accessory belt listed). These documents describe a beltless accessory system with electrically driven ancillaries.

Why no belt? The Prius powers traditional belt-driven accessories electrically, so there’s nothing for a belt to spin under the bonnet:

• Electric water pump: The engine coolant pump is electric, so there’s no pulley to drive.
• Electric A/C compressor: The air-con compressor has its own motor and uses hybrid-safe oil
