Parts for your 2012 Subaru Impreza-Timing belt kit

2012 Subaru Impreza timing-belt-kit — is it used?

For the 2012 Subaru Impreza (the regular hatch and sedan, non‑WRX), a timing-belt-kit isn’t relevant because this model runs Subaru’s FB‑series engines (FB20 2.0L and, in some markets, FB16 1.6L) which use a timing chain, not a belt. That means there’s no timing belt to replace, and no “timing-belt-kit” fitted from factory on these engines.

This isn’t guesswork. Technical sources back it up: the Subaru Factory Service Manual for the FB‑series details a chain‑driven DOHC layout, Subaru’s maintenance schedules for MY12 Impreza don’t list a timing belt replacement interval, and major parts catalogues (e.g., Gates and Dayco) don’t offer a timing-belt kit for 2012 Impreza FB engines, instead noting a chain system.

Why the change? Subaru moved from the older EJ engines (belt-driven) to the FB family with chains for improved durability, packaging, and lower servicing overheads. A chain runs in oil under the timing cover and is designed to last the life of the engine when looked after properly.

• No kit needed: there’s no timing belt, tensioner, or idler kit to schedule or budget for on a 2012 Impreza FB16/FB20.
• What to maintain instead: stick to on-time oil changes with the correct specification and viscosity so the hydraulic chain tensioners stay happy. Poor oil quality is the enemy of timing chains.
• What to watch: if there’s rattling from the front of the engine on cold start, an oil leak near the timing cover, or the check engine light with cam/crank correlation codes, get it checked. Chains are robust, but guides and tensioners can wear if servicing’s been neglected.

Note for buyers and owners: the 2012 WRX/STI performance models of that era use EJ engines with a timing belt, but they’re a different drivetrain to the standard 2012 Impreza. If it’s the regular 2012 Impreza runabout, it’s a timing chain engine and doesn’t take a timing-belt-kit.

FAQs

Does a 2012 Subaru Impreza have a timing belt or a chain?
It has a timing chain. The 2012 Impreza uses Subaru’s FB‑series engines (FB20/FB16), which are chain‑driven. Only the separate WRX/STI models of that period run the older EJ belt‑driven engines.

Do I need a timing-belt-kit for servicing my 2012 Impreza?
No. There’s no timing belt on the standard 2012 Impreza, so no kit to replace. Focus on regular oil changes with the correct spec and keeping an ear out for unusual timing noises.

What maintenance keeps the timing chain healthy on a 2012 Impreza?
Use quality oil at the correct viscosity, stick to service intervals, and fix any oil leaks promptly. If there’s a rattle on cold start or warning lights relating to cam timing, have a technician inspect the chain tensioner and guides under the bonnet.
