Parts for your 2019 Toyota Land cruiser-Drive belt

2019 Toyota Land Cruiser drive belt — what it does and when to replace it

The 2019 Toyota Land Cruiser does use an accessory drive belt (serpentine belt), so it’s absolutely relevant to servicing. This is confirmed in Toyota’s 200 Series (2019) Repair Manual available via Toyota Service Information (TIS), the Toyota Electronic Parts Catalogue listing a V‑ribbed “fan and alternator” belt and automatic tensioner for both the 4.5L V8 diesel (1VD‑FTV) and 5.7L V8 petrol (3UR‑FE), and by major belt manufacturers’ application catalogues (e.g., Gates and Dayco), which specify serpentine belts for this model year.

On a 2019 Land Cruiser, the drive belt loops around multiple pulleys to drive key ancillaries off the crankshaft. It keeps the charging system topped up, the cabin cool, and the steering light. Depending on engine variant and market spec, it typically drives:

• Alternator (charging the battery and powering electrics)
• Air conditioning compressor
• Power steering pump
• In some variants, the engine fan and/or water pump

Because it’s a rubber V‑ribbed belt working in heat, dust, and under the bonnet splash, it gradually wears. Toyota’s factory schedule calls for inspection at routine services
