Parts for your 2022 Toyota Land cruiser-Drive belt

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, if they’re noisy or rough, swap them with the belt. Correct routing and proper tension (set by the auto tensioner) are critical—an incorrectly routed belt can strand the vehicle. For many owners, a workshop visit is the easiest path, those DIY‑inclined should follow the LC300 Repair Manual procedure and belt routing diagram.

Popular questions

How often should the LC300 drive-belt be replaced?
There’s no single kilometre figure for every Land Cruiser, so Toyota focuses on inspection at each service and replacement on condition. In typical use, many workshops see belts last around 100,000–150,000 km or 6–8 years. If the vehicle tows heavy, spends time in the heat or dust, or shows any cracking, glazing, squealing, or slippage, replace earlier.

What noises point to a crook drive-belt or tensioner?
A sharp chirp on cold start or a squeal with the A/C on usually hints at belt slip or a tired tensioner. If the sound changes with electrical load (lights, demister, winch), think alternator pulley/belt grip. Any grinding or rumbling from the front of the engine often points to an idler or tensioner bearing rather than the belt itself.

Does the 2022 Land Cruiser have a timing belt?
No. Both LC300 engines use timing chains. The external V‑ribbed belt only drives accessories like the alternator and A/C compressor, so timing belt replacement isn’t part of this model’s servicing. Toyota’s New Car Features and Repair Manual materials specify chain‑driven valve timing for these engines.
