Peugeot 306 Alternator Replacement Parts

The Peugeot 306 ran as a single generation from 1993 to 2002, with a significant facelift in 1997 that updated the bodywork and some mechanical ancillaries. Because alternator fitment follows the engine code rather than the model year, two cars from either side of that 1997 facelift boundary can share an alternator if they share the same engine code — but mounting brackets and ancillary routing can change mid-production, so confirm the exact match with the breaker against both registrations before buying.

Yes — the engine code is the single most important detail for alternator fitment, more so than the year or trim level. You'll find the engine code on your V5C logbook or via a HPI/VIN check, and giving it to the breaker will let them match the part far more accurately than the year alone. Different 306 engines — such as the 1.4, 1.6, 1.8, 1.9 diesel, and 2.0 — used different alternators, so never assume one size fits all.

Trim level — XR, XN, SR, GLX, or GTI-6 — does not in itself affect alternator fitment; what matters is the engine code fitted to the car. The GTI-6 used the high-output 2.0 16v engine, so its alternator will differ from the one on a 1.4 or 1.6 XR, but two 306s with the same engine code should use the same alternator regardless of badge. Bear in mind that breakers may price GTI-6 parts at a premium, so it's worth confirming the engine code first to see whether a cheaper donor car with the same engine would serve you just as well.

Yes, petrol and diesel variants of the 306 used different engines and therefore different alternators, so you should not mix across fuel types. Within diesel variants — for example, the 1.9 naturally aspirated versus the 1.9 turbodiesel HDi — the engine codes differ and the alternators may not be interchangeable. Always supply the engine code and fuel type to the breaker to make sure you're quoted the right unit.

The 306 is generally described in three phases: Phase 1 (1993–1997), Phase 2 (1997–1999), and Phase 3 (1999–2002), with the most notable styling revision arriving at the 1997 facelift. Whether an alternator crosses those phase boundaries comes down to whether the engine codes match — if they do, fitment is likely, but ancillary mounting details can change across a facelift, so confirm compatibility with the breaker using both registrations rather than assuming the phase alone tells the whole story.

Gearbox type — manual or automatic — can influence ancillary positioning and belt routing on some engines, so it is worth mentioning to the breaker alongside your engine code. In most cases the engine code is the dominant factor, but supplying both details gives the breaker the best chance of matching the right unit to your car. Never assume an alternator from a manual 306 will drop straight into an automatic of the same year without checking first.
