Used Alfa Romeo 147 Timing Chain

It depends on the engine. The 1.6 and 1.8 Twin Spark petrol engines in the 147 use a timing belt, not a chain, so there is no timing chain to source for those units. The 3.2 V6 GTA engine uses a timing chain, so if you have that variant you are in the right place; for all other 147 engines, you need to be searching for a timing belt kit instead.

The 147 GTA was produced from 2003 to 2005 using the Busso 3.2 V6 engine throughout its run, so the engine architecture remained consistent across those years. In principle a chain from another GTA of this period should correspond, but internal running changes can occur mid-production, so you should always confirm the exact engine code with the breaker against your registration before purchasing. Supplying your engine code from the V5 or a VIN check gives the breaker the best chance of pulling the correct part.

The 147 received a facelift for the 2005 model year, but the only engine in the 147 range that carries a timing chain is the 3.2 V6 GTA, which was not carried over into the facelift generation. This means the facelift 147 range does not include any timing-chain engine, so the question of cross-generation chain interchange does not arise in practice. If you have a facelift 147, you almost certainly need a timing belt rather than a timing chain.

No – trim level has no bearing on timing chain fitment. The chain is determined entirely by the engine, and all 147 GTAs used the same 3.2 V6 unit regardless of any specification differences. Focus on supplying the correct engine code to the breaker rather than worrying about trim designation.

Yes, the engine code is the single most important detail for getting the right timing chain, and it overrides the badge or year on its own. Always quote the engine code directly from your V5 or a reliable VIN check when requesting a quote from a breaker, as this removes ambiguity and ensures you are matched to the correct parts. If your code differs from what you expected, flag this to the breaker explicitly so they can cross-reference it accurately.

A standard 147 Twin Spark left the factory with a timing belt, not a chain, so under normal circumstances you need a belt kit. However, if the vehicle has had a non-standard engine transplant – for example a 3.2 V6 fitted from a GTA – then a timing chain would be relevant. If you are unsure what engine is actually in the car, check the engine code stamped on the block or run a VIN check, then confirm with the breaker what you have before ordering any parts.
