Used Peugeot 306 Intercooler

Only the turbocharged diesel and turbocharged petrol variants of the 306 have an intercooler — naturally aspirated petrol engines do not use one at all. The main engines you'll find intercoolers on are the 1.9 TD and 2.0 HDi diesels, and the turbocharged 1.8 and 2.0 petrol units found in the GTi-6 and Rallye. If your 306 is a standard naturally aspirated petrol (1.1, 1.4, 1.6, 1.8, or 2.0 non-turbo), there is no intercooler fitted and you may be thinking of a different component such as a radiator or oil cooler.

The Peugeot 306 ran from 1993 to 2002, with a significant facelift in 1997 that marks the Phase 1 and Phase 2 split. The engine codes themselves often carried over across this boundary — for example the 1.9 TD — but ancillary mounting points and pipework routing can differ between phases, so a Phase 1 intercooler may not drop straight into a Phase 2 car even with the same engine code. You should confirm fitment with the breaker using your exact registration and, ideally, your engine code from your V5, before buying.

Yes, the engine code is the most important detail you can supply — it tells the breaker far more than the year or body style alone. The 306 HDi used the 2.0 litre DW10 family engine (code RHY being the most common), and intercoolers for that unit differ from those on the older 1.9 TD (XUD-based) engines. Pull your engine code from your V5 logbook or a VIN check and quote it to the breaker when requesting a quote.

Trim level does not affect intercooler fitment — what matters is the engine fitted, not whether the car is badged LX, SR, XSi, or GTi-6. That said, the GTi-6 uses a turbocharged 2.0 petrol engine which is a different unit entirely from the diesel engines in mainstream LX or SR models, so those intercoolers are not interchangeable. Focus on matching the engine code rather than the trim name, and expect no cosmetic differences between intercoolers from different trim levels carrying the same engine.

Body style does not affect intercooler fitment on the 306 — the intercooler is determined by the engine and its ancillaries, not by whether the car is a hatchback, saloon, or estate. As long as the engine code matches, the body style of the donor vehicle is irrelevant. Confirm with the breaker that the pipework and mounting brackets are included if you need a complete assembly, as these are what can vary between individual cars.

Without knowing at minimum the engine code, buying blind carries real risk, as intercoolers across the 306's 1993–2002 production run are not all interchangeable even within the same engine family. Ask the breaker to confirm the engine code from the donor car's V5 or VIN plate and compare it to yours before committing. If the seller cannot provide that information, it is safer to get quotes through Findapart where dismantlers can verify fitment against your registration.
