Parts for your 2000 Toyota Hilux-Timing belt kit

2000 Toyota Hilux timing-belt-kit — what’s fitted and what to service

Technical sources including Toyota factory repair manuals (Hilux LN/RZN/VZN series, 1997–2004), the Toyota Electronic Parts Catalogue, and Australian/New Zealand application catalogues from Gates and Dayco agree on this: whether a timing-belt-kit is relevant for a 2000 Toyota Hilux depends on the engine. The 3.0L 5L/5L-E diesel and the 3.4L 5VZ-FE V6 petrol use a timing belt, so a timing-belt-kit absolutely applies. The 2.7L 3RZ-FE (and related RZ petrol engines) use a timing chain, so a timing-belt-kit is not used on those variants. Some markets also offered the 1KZ-TE turbo-diesel around this era, which also runs a belt.

Where a timing-belt-kit is not used (e.g., 3RZ-FE), it’s because the engine employs a steel timing chain with hydraulic tensioning and chain guides, designed for long service life with engine oil rather than periodic belt replacement. In those chain-driven engines, the relevant service parts are chain, guides, and tensioner—not a rubber belt kit.

For belt-driven 2000 Hilux engines, a timing-belt-kit keeps the cam and crank perfectly in sync so the engine runs sweet and reliably. A proper kit typically includes the belt, tensioner, idler pulleys, and often a water pump and cam/crank seals. That bundle helps ensure all the wear items in the belt path are refreshed together, reducing noise, slop, and the risk of premature failure after only doing the belt on its own.

Servicing advice that aligns with Toyota schedules and major belt manufacturers in AU/NZ: replace the timing belt at roughly 100,000–150,000 km or 5–7 years (whichever comes first). Dusty work, heavy towing, lots of short trips, or high heat under the bonnet can justify the shorter end of that range. When the front of the engine is open, it’s smart to replace the tensioner, idlers and water pump at the same time—labour is the big cost, and these parts age together.

• Use a quality kit matched to the exact engine code (5L/5L-E or 5VZ-FE).
• Inspect cam and crank seals, replace if weepy to keep the new belt clean and grippy.
• Follow torque specs and alignment marks precisely, hand-rotate the engine two full turns and re-check timing before start-up.
• After fitting, recheck belt tension and listen for abnormal whirring or chirps on first run.

If the Hilux in question is the chain-driven 3RZ-FE, there’s no timing belt to replace. Routine oil changes with the correct grade are the “belt service” in that case—good oil keeps the chain, guides and tensioner happy for the long haul.

Popular questions

Which 2000 Hilux engines actually have a timing belt?
According to Toyota manuals and AU/NZ parts catalogues, the 3.0L 5L/5L-E diesel and 3.4L 5VZ-FE V6 petrol are belt-driven. The 2.7L 3RZ-FE petrol uses a chain and therefore doesn’t take a timing-belt-kit. Some markets also saw the 1KZ-TE turbo-diesel, which uses a belt.

How often should the timing-belt-kit be replaced?
For belt-driven 2000 Hilux engines, plan on roughly 100,000–150,000 km or 5–7 years, whichever comes first. Vehicles that tow, see lots of dust, or do frequent short trips are better served at the earlier end of that range. Replacing the tensioner, idlers and water pump with the belt is recommended.

What symptoms suggest the belt system needs attention?
Look out for a cold-start squeak, ticking from the front cover, coolant weep from the water pump, oil around the cam/crank seals, or a belt that looks cracked, shiny, or contaminated. Any of those are a nudge to book the kit replacement before it becomes a breakdown.
