2004 Toyota Land Cruiser Drive Belt — What It Does and When to Replace It

Yes, the 2004 Toyota Land Cruiser uses a drive belt. Technical sources—namely the Toyota factory repair manual for the 100 Series (UZJ100/HDJ100), Toyota Electronic Parts Catalogue (EPC) belt diagrams, and AU/NZ application catalogues from major belt manufacturers—show both the 4.7‑litre 2UZ‑FE petrol and the 4.2‑litre 1HD‑FTE turbo‑diesel use accessory drive belts (serpentine and/or auxiliary belts). These belts run the alternator, power steering pump, air‑conditioning compressor and, depending on engine variant, the coolant pump.

On this Land Cruiser, the drive belt is the quiet workhorse that keeps daily functions alive. Without it, charging stops, steering gets heavy, A/C drops out and the engine can overheat if the water pump on that variant is belt‑driven. The 2UZ‑FE petrol V8 uses a serpentine belt with an automatic tensioner, the 1HD‑FTE diesel also uses belt‑driven accessories with a tensioner setup. Don’t confuse this with the petrol V8 timing belt that synchronises the cams—different belt, different job.

For servicing, the drive belt should be inspected at each routine service (every 10,000–15,000 km) for wear and correct tension. Typical replacement is around 80,000–120,000 km or 4–6 years in local conditions, sooner if there’s noise, cracking or glazing. Always check the tensioner and idler pulleys at the same time—if the tensioner indicator is out of range, or the pulley bearings feel rough, replace them with the belt. Following the belt routing diagram under the bonnet helps avoid misrouting.

• Replace the belt if there are cracks across the ribs, missing chunks, fraying edges or a glazed/shiny surface.
• Investigate squeals or chirps on cold start—often a stretched belt or weak tensioner.
• Watch for a flickering battery light, heavy steering or poor A/C—common signs of slip.
• Use quality belts sized to the exact engine code (2UZ‑FE or 1HD‑FTE) and accessory configuration.
• Consider a belt-and-tensioner kit to restore correct clamping force and alignment in one go.

Good maintenance here is cheap insurance on a 100 Series. A fresh belt and healthy tensioner keep the alternator charging, the steering light and the air‑con cold—whether it’s the commute or a long run across the Nullarbor.

Popular questions

Which engines in the 2004 Land Cruiser use a drive belt?
The 4.7‑litre 2UZ‑FE petrol and the 4.2‑litre 1HD‑FTE turbo‑diesel both use accessory drive belts. The petrol typically runs a serpentine belt with an automatic tensioner, the diesel uses belt‑driven accessories as well. Some variants may have an additional belt for specific accessories.

How often should the drive belt be replaced?
Inspect at every service and plan on replacement around 80,000–120,000 km or 4–6 years, earlier if there’s noise, cracking or glazing. Always check the tensioner and idlers at the same time, as a weak tensioner can shorten belt life.

What are the signs the belt or tensioner needs attention?
Squeal or chirp on cold start, visible cracks or rib wear, a battery warning light, heavy steering or reduced A/C performance. If the tensioner indicator sits out of its normal range or the pulley feels rough, it’s time to replace it with the belt.
