Parts for your 2015 Subaru Impreza-Timing belt kit

2015 Subaru Impreza timing-belt-kit — is it a thing?

Short answer: a timing-belt-kit isn’t used on the 2015 Subaru Impreza. This model runs Subaru’s FB-series 2.0-litre engine, which uses a timing chain, not a belt. That’s confirmed in Subaru’s Factory Service Manual for the MY2015 Impreza, the Owner’s/Maintenance Schedule (which doesn’t list a timing-belt replacement interval), and common parts catalogues from Gates and Dayco in AU/NZ that show no timing belt kit for the FB20 engine.

Why no timing-belt-kit? The FB20’s chain runs inside the engine, lubricated by engine oil, and is designed as a life-of-engine component. Unlike the old EJ-series Impreza engines (pre-2012 in most trims) that used rubber timing belts with scheduled replacement, the 2015 Impreza’s chain setup removes the need for periodic belt, idler and tensioner kit changes.

What should owners care about instead? Keeping that chain happy comes down to good oil and regular servicing. Using the correct oil grade and spec, and sticking to the service intervals, helps prevent chain and tensioner wear. Subaru’s guidance for MY2015 points to regular oil changes being critical—poor lubrication is the main reason chains stretch or tensioners get noisy.

• Listen for rattle on cold start or at idle, persistent chain noise deserves a specialist check.
• If oil change history is unknown, get back on schedule with quality oil and a proper filter.
• While there’s no timing-belt-kit, the auxiliary/serpentine belt does wear—inspect and replace it as needed.
• Water pump service isn’t tied to a timing belt on this engine. Replace on condition (leaks, noise) or during major cooling system work.

Parts sites sometimes show timing-belt-kits generically under “Impreza”, which can be confusing. That usually references older EJ engines or other Subaru models. For a 2015 Impreza 2.0 (FB20), a timing-belt-kit simply isn’t applicable.

Technical sources referenced: Subaru Factory Service Manual (MY2015 Impreza, FB20 engine), Subaru Owner’s/Maintenance Schedule (MY2015), Subaru TechTIPS on FB-series timing chains, and AU/NZ parts catalogues from Gates and Dayco indicating chain-driven camshafts for FB20.

Popular questions

Does the 2015 Subaru Impreza have a timing belt or a chain?
It has a timing chain. The FB20 engine used in the 2015 Impreza is chain-driven, so there’s no timing-belt-kit to replace. This aligns with Subaru’s MY2015 maintenance information and major AU/NZ parts catalogues that don’t list a belt for this engine.

When should the timing chain be replaced on a 2015 Impreza?
There’s no scheduled replacement interval. With correct oil and regular servicing, the chain is intended to last the life of the engine. If you notice chain rattle on start-up, fault codes for cam/crank correlation, or metal in the oil, get it inspected—those are signs of wear or a tensioner issue.

Why do some websites still show a timing-belt-kit for my 2015 Impreza?
Because “Impreza” spans many years and engines. Older EJ-series models used timing belts, and some databases lump results together. For a 2015 2.0-litre FB20, a timing-belt-kit isn’t relevant—look instead at servicing the serpentine belt and keeping oil changes up to date.
