Parts for your 2010 Subaru Tribeca-Timing belt kit

2010 Subaru Tribeca timing-belt-kit — is it used?

The 2010 Subaru Tribeca doesn’t use a timing-belt-kit at all. This model runs Subaru’s 3.6‑litre EZ36 H6 petrol engine, which is chain-driven. In the factory documentation for the 2010 Tribeca (Subaru Service Manual, ME(H6) Timing Chain section), the camshafts are driven by a multi-row timing chain with guides and hydraulic tensioners, not a rubber timing belt. Subaru’s maintenance schedules of the era also list timing belt replacements only for four‑cylinder EJ engines, there’s no belt service interval for the H6 because it uses a chain. Genuine parts catalogues for the EZ36D further show timing chains, guides and tensioners — and no timing belt or belt kit.

That’s why a timing-belt-kit isn’t relevant for a 2010 Subaru Tribeca: there’s no belt to replace. The timing chain runs internally in the engine, lubricated by engine oil, and is designed for long service life without scheduled replacement. Owners won’t find a periodic “timing belt” change on the service sheet for this model.

What should be looked after instead? Good oil and regular servicing. Because the chain, guides and tensioners rely on clean, correct‑spec oil, timely oil and filter changes are crucial — especially if the vehicle tows, does short trips, or sees hot Aussie or Kiwi summers. A stretched or poorly lubricated chain can rattle on start‑up, trigger cam/crank correlation fault codes, or affect performance.

• Stick to the recommended oil grade and change intervals, shorten them for severe use.
• Listen under the bonnet for abnormal rattles at cold start, persistent noise warrants inspection.
• Check for oil leaks around timing cover/cam covers and keep the accessory (serpentine) belt in good nick.
• The water pump on the EZ36 is not part of a timing-belt service, replace it only if it leaks or the bearing’s noisy.

Popular questions about 2010 Subaru Tribeca timing-belt-kit

Does the 2010 Subaru Tribeca have a timing belt or a chain?
It has a timing chain. The EZ36 H6 engine uses a chain with hydraulic tensioners and guides, so there’s no timing-belt-kit to fit or replace. Subaru’s H6 engines of this generation aren’t scheduled for timing belt changes.

When should the timing chain be replaced on a 2010 Tribeca?
There’s no routine replacement interval. The chain is designed for the life of the engine. Replacement is only considered if there are symptoms like persistent start‑up rattles, cam/crank correlation fault codes, metal in the oil, or confirmed wear of guides/tensioners. Regular oil changes help the chain system last.

What maintenance replaces a “timing belt service” on this model?
Focus on timely oil and filter changes, correct oil grade, accessory belt inspection/replacement, coolant service to schedule, and checks for leaks or unusual noises. The water pump isn’t tied to a timing-belt job on the EZ36, only replace it if faulty.
