Ford S-Max Glow Plugs Replacement Parts

The Ford S-Max was sold with both petrol and diesel engines, and glow plugs are a diesel-only component used to pre-heat the combustion chamber for cold starting. If your S-Max is a diesel — which covers the vast majority of UK S-Max sales, including the 1.6 TDCi, 2.0 TDCi, and 2.2 TDCi engines — it will have glow plugs. If your S-Max is a petrol variant, it has no glow plugs at all; if you're having cold-start or ignition issues on a petrol, you'd be looking at spark plugs instead.

The Ford S-Max ran as a single generation from 2006 to 2015, with a facelift in 2010, so a 2008 and a 2013 car are both first-generation models but sit either side of that facelift boundary. Glow plug compatibility is driven by engine code above everything else — if both cars share the same engine code (for example, both running the same 2.0 TDCi UFDA or TXDA unit), the plugs are very likely the same, but confirm this with the breaker against both registration numbers before buying. Do not rely on year alone.

Trim level has no bearing on glow plug fitment whatsoever — glow plugs follow the engine, not the badge or trim specification. A 2.0 TDCi in a Zetec S-Max uses the same glow plugs as a 2.0 TDCi in a Titanium, provided the engine codes match. When sourcing from a breaker, give them your engine code (found on your V5C or via a VIN check) rather than your trim name.

The number of glow plugs matches the number of cylinders — a four-cylinder S-Max diesel such as the 1.6 TDCi, 2.0 TDCi, or the five-cylinder 2.2 TDCi will have four or five plugs respectively, one per cylinder. When buying from a breaker, confirm whether you need a full set or individual plugs, and make sure the engine code on the donor vehicle matches yours exactly. Most UK breakers can supply a set pulled from a donor engine of the correct specification.

This is worth exploring, because the S-Max, Galaxy, and Mondeo of the same era shared Ford's TDCi engine family, and glow plugs from a matching engine code in any of those vehicles may well interchange. The key is matching the engine code exactly, not the model name — if a Galaxy donor and your S-Max both carry the same code, the plugs are the same part. Run both registrations past the breaker and ask them to cross-reference the engine codes before confirming the sale.

Yes, the first-generation S-Max ran through to 2015, so a 2015 car is still a Mk1, though the second generation arrived around 2015–2016 to replace it. For glow plug compatibility with an earlier first-gen donor, the engine code remains the deciding factor — confirm your code via the V5C or a VIN check, supply it to the breaker, and ask them to match it precisely rather than going on year alone.
