2004 Toyota Highlander (Kluger) Drive Belt — Purpose, Care and When to Replace

Yes, a drive belt is used on the 2004 Toyota Highlander (known as Kluger in Australia and New Zealand). Toyota’s factory repair information for the Highlander/Kluger and major aftermarket catalogues (Gates and Dayco) list an accessory/serpentine drive belt for both engines offered that year: the 2.4‑litre 2AZ‑FE four‑cylinder and the 3.3‑litre 3MZ‑FE V6. Note: the V6 also has a timing belt for the camshafts, which is separate from the external accessory drive belt discussed here.

The drive belt’s job is to spin key ancillaries off the crankshaft. On the 2.4‑litre it typically drives the alternator, power steering pump, A/C compressor and water pump. On the 3.3‑litre V6 it drives the alternator, power steering pump and A/C compressor (the V6 water pump is driven by the timing belt). If the belt slips or fails, expect flat battery symptoms, heavy steering, or no air‑con — and on the 2.4‑litre, engine overheating.

For servicing, a good rule is to inspect the belt at each service or at least every 15,000 km/12 months. Quality EPDM belts don’t always crack visibly, so look and listen for:

• Cold‑start squeal, chirps or a rubbery burning smell
• Glazing, fraying, missing ribs, or contamination with coolant/oil
• Battery light flicker, heavy steering, or intermittent A/C engagement

Replacement is typically due around 90,000–120,000 km or 6–7 years, sooner in hot, dusty or stop‑start conditions. It’s smart to check the automatic tensioner and idler pulleys at the same time, a weak tensioner or rough pulley will shorten a new belt’s life.

Under the bonnet there’s usually a routing decal, otherwise snap a photo before removal. Use a long spanner or breaker bar on the tensioner to relieve tension, slip the old belt off, route the new belt, and release the tensioner smoothly. After fitting, start the engine and watch the belt track — no wobble, no noise. If noise persists, re‑check alignment and pulley condition. For the V6, remember the accessory belt is separate to the timing belt schedule, so even if the timing belt has been done, the serpentine belt and tensioner still deserve their own inspection and replacement plan.

FAQs

How often should the 2004 Highlander/Kluger drive belt be replaced?
Most owners will be well served changing it every 90,000–120,000 kilometres or 6–7 years, with inspections each service. High heat, short trips and dusty roads may justify earlier replacement.

What are the signs the drive belt or tensioner is on the way out?
Look for cold‑start squeals, glazing or frayed ribs, heavy steering, a flickering battery light, or poor A/C performance. If the tensioner arm jitters or the pulley feels rough/spins noisily by hand, replace it with the belt.

Does the V6 have both a timing belt and a drive belt?
Yes. The 3.3‑litre V6 uses a timing belt inside the covers and an external serpentine drive belt for accessories. They have different jobs and intervals, so plan service for both.
