Parts for your 2015 Subaru Exiga-Timing belt kit

2015 Subaru Exiga timing-belt-kit — is it used, and does it need replacing?

For the 2015 Subaru Exiga (including the late-model Exiga and the Exiga Crossover 7), a timing-belt-kit isn’t relevant. This model runs Subaru’s FB-series engines (FB20 2.0‑litre or FB25 2.5‑litre, depending on trim), which use a timing chain rather than a rubber timing belt.

This isn’t just hearsay. Subaru factory service information for FB‑series engines (as published in Subaru’s technical manuals and STIS), lists a chain-driven cam system with hydraulic tensioners, and no scheduled belt replacement. Genuine Subaru parts catalogues for the 2015 Exiga/Crossover 7 show a timing chain, guides, and tensioners — there’s no timing belt, idlers, or belt kit for this model year. The owner’s maintenance schedule also doesn’t call up timing belt replacement, only the accessory/drive belt is a routine service item.

Why Subaru didn’t use a belt here comes down to design: the FB engine’s chain runs inside the engine, bathed in oil, for long service life and stable cam timing. Chains aren’t a fit‑and‑forget item forever, but they don’t have the fixed replacement interval that older EJ belt engines had.

What owners should do instead of shopping for a timing-belt-kit:

• Stick to regular oil changes with the correct spec oil and quality filters — clean oil is critical for the chain tensioners.
• Listen for prolonged rattles on cold start, poor running, or cam/crank correlation fault codes — these can flag chain, guide, or tensioner issues.
• Service the accessory/serpentine belt and its idler(s) as needed, this is separate from the timing system.

Worth noting for clarity: earlier Exiga models (pre‑facelift, using EJ‑series engines, especially turbo variants) did have a timing belt with a set replacement interval (often around 105,000 km or 105 months). That guideline doesn’t apply to the 2015 Exiga with FB engines, where no timing-belt-kit is fitted or required.

Popular questions about 2015 Subaru Exiga timing-belt-kit

Does a 2015 Subaru Exiga have a timing belt or a chain?
It has a timing chain. The 2015 Exiga’s FB‑series engine uses a chain with hydraulic tensioners inside the engine. There’s no timing-belt-kit for this model year.

When should the timing chain be replaced on a 2015 Exiga?
There’s no fixed replacement interval. With correct oil servicing, the chain is designed to last the life of the engine. Replacement is only considered if there are symptoms like persistent start‑up rattles, cam/crank timing faults, or abnormal chain wear found during diagnosis.

Which engine is in the 2015 Exiga, and does that change belt/chain needs?
Depending on trim, it’ll be an FB20 (2.0‑litre) or FB25 (2.5‑litre), both chain‑driven. Neither uses a timing-belt-kit. Only earlier EJ‑engined Exiga models used belts.
