Used Ford Focus AC Compressor

The Focus Mk3 ran from 2011 to 2018 with a facelift in 2014, so a 2013 car sits pre-facelift and a 2015 sits post-facelift — both are within the same generation, but Ford made ancillary and mounting changes across that 2014 boundary that could affect compressor compatibility. The engine code is the most important detail here: if both cars share the same engine code (found on your V5 or via a VIN check), there is a reasonable chance the compressor will match, but you should confirm directly with the breaker against both registrations before buying. Never assume fitment solely from the year.

Yes, the Mk2 Focus ran from 2004 to 2011 and the Mk3 from 2011 to 2018, and these are distinct generations with different engine families, so compressors are not considered interchangeable across that boundary. Always supply the breaker with your engine code — not just the generation name — as that is the single most reliable way to identify the correct unit. Confirm fitment with the breaker against your registration before purchasing.

No — trim level does not affect which AC compressor your Focus needs; Zetec, Titanium, ST-Line and other trim grades on the same generation and engine code will use the same compressor. What you might notice is cosmetic variation in surrounding components if the donor car is a different trim, but the compressor itself is a mechanical part that follows the engine code, not the badge. Give the breaker your engine code and registration to make sure the unit matches, and ignore the trim name on the listing.

Almost certainly not — petrol and diesel engines in the Focus use different compressors even within the same model year and generation, because the compressor is matched to the engine's drive system and ancillary layout. Fuel type is one of the key fitment criteria alongside the engine code, so always specify both when contacting a breaker. Confirm fitment against your exact registration before agreeing a purchase.

Gearbox type can affect ancillary belt routing and mounting on some engines, so it is worth mentioning to the breaker whether your Focus is a manual or automatic when requesting a quote. The engine code remains the most important detail to supply, but flagging the gearbox type as well helps the breaker cross-check the donor vehicle more accurately. Always confirm fitment against your registration rather than relying on the year and engine code alone.

A 2008 Focus is a Mk2, which ran from 2004 to 2011, so a 2010 donor car is also a Mk2 and within the same generation. That said, the engine code is still the most important check — both vehicles should share the same engine code for the compressor to be a reliable match, and you should confirm with the breaker that no ancillary changes were made between those model years on your specific engine. Supply both registrations to the breaker and ask them to verify before buying.
