Cheap Peugeot 407 Cylinder Head

The Peugeot 407 ran from 2004 to 2011 in a single generation, with a facelift arriving in 2008 that brought styling updates but no fundamental engine architecture changes; what matters far more than the year is whether the engine code on the donor car matches yours exactly, as that is stamped on the block and listed on your V5. If you are crossing the 2008 facelift boundary, confirm with the breaker that ancillary ports, coolant galleries, and mounting points are identical to your specific registration before purchasing. Never assume a pre-facelift head will drop straight onto a post-facelift block without that check.

No – petrol and diesel cylinder heads are completely different components with different combustion chamber designs, valve configurations, and compression ratios, and they are not interchangeable under any circumstances. Always confirm your fuel type with the breaker alongside your engine code, which is the single most reliable way to make sure the head matches your engine and not just your model badge.

Trim level – whether your car is an SE, SX, or Sport – has no bearing on cylinder head fitment whatsoever, as the head is determined entirely by the engine code, not the badge on the bootlid. You may find that cosmetic ancillaries differ between trim levels, but the head itself is the same across trims sharing the same engine code, so give the breaker your engine code rather than your trim name and you will get the right part.

The 407 was offered in three body styles in the UK – the saloon, the SW estate, and the Coupé – but body style alone does not determine cylinder head fitment. Provided the engine codes match, a head from a saloon, SW, or Coupé should be mechanically the same, though you should always confirm this with the breaker against your specific registration as ancillary configurations can vary.

The 2.0 HDi engine family used in the 407 covers more than one engine code, and even engines that sound the same from the outside can have different head specifications depending on power output and emissions standard, so the engine code rather than the displacement is what the breaker needs. You will find your engine code on your V5 logbook or via a VIN check, and supplying it upfront will save time and reduce the risk of ordering the wrong head. Do not rely on power output figures alone as a matching method.

A cylinder head itself is a mechanical component and does not typically contain its own ECU, but if the head is supplied with associated sensors or components already attached, whether those need coding or pairing to your vehicle is something you should confirm with the breaker or a diagnostic specialist against your specific registration. Findapart connects you with breakers who can advise on what is included with the part and flag any coding considerations before you buy.
