2022 Toyota Land Cruiser drive-belt: what it does and when to replace it

Yes, the 2022 Toyota Land Cruiser 300 Series uses a V‑ribbed (serpentine) drive-belt. Toyota’s Land Cruiser 300 Repair Manual and New Car Features documents note an external accessory belt on both the 3.5‑litre twin‑turbo petrol V6 (V35A‑FTS) and the 3.3‑litre twin‑turbo diesel V6 (F33A‑FTV), while the Toyota Electronic Parts Catalogue lists the V‑ribbed belt and related tensioner/idler pulleys for these engines. That makes the drive-belt a relevant, serviceable item on the LC300.

Under the bonnet, the belt spins key accessories off the crank pulley. Depending on engine spec, that includes the alternator and A/C compressor, and on some variants the coolant pump. The LC300 uses electric power steering, so there’s no belt‑driven P/S pump load like older models. Even so, the belt is essential for charging the battery, keeping cabin air con cold, and—where applicable—helping coolant circulation.

For servicing, the sensible approach mirrors Toyota’s guidance: inspect the drive-belt at regular service intervals and replace on condition. In Aussie and Kiwi terms, a quick look every service (10,000–15,000 km) is smart, especially if the vehicle tows, works off‑road, or sees dusty, muddy conditions. Many owners replace the belt proactively around 100,000–150,000 km or 6–8 years, but condition always trumps the calendar.

• Check for cracks across the ribs, glazing/shiny patches, fraying, chunking, or contamination (oil/coolant).
• Listen for squeals or chirps on cold start, heavy electrical load, or with the A/C on—often belt or tensioner related.
• Watch for warning signs: battery light, dim headlights at idle, weak A/C, or rising temps if the water pump is belt‑driven.

When replacement time comes, use a quality belt sized to the exact engine and accessory layout. It’s good practice to inspect the automatic tensioner and idler pulleys at the same time
