Used Ford Mondeo Power Steering Pump

It depends on the generation. The Mk3 Mondeo (2000–2007) used a hydraulic power steering pump driven by the engine, so a physical pump exists on those cars. The Mk4 Mondeo (2007–2014) and Mk5 (2015–2024) transitioned to electric power steering (EPS) on most variants, meaning there is no hydraulic pump to replace — if your Mk4 or Mk5 steering is failing, the fault is likely in the EPS motor or column unit, not a pump.

Both sit within the Mk3 generation (2000–2007), so there is a reasonable chance of compatibility, but the Mk3 received a facelift in 2003 and engine variants across the range include 1.8, 2.0, and 2.5 petrol as well as 2.0 and 2.2 TDCi diesels — the pump can differ between engine sizes. Give your registration to the breaker so they can confirm the correct pump for your specific engine rather than just the model year.

No — the Mk4 Mondeo (2007–2014) uses electric power steering and has no hydraulic pump, so a Mk3 hydraulic pump has no application on a Mk4 and cannot be fitted as a like-for-like replacement. If you have a Mk4 with steering issues, you need to look at the EPS column or motor assembly instead.

Yes, engine size is an important factor — the Mk3 Mondeo was offered with 1.8 and 2.0 petrol, a 2.5 V6 petrol, and 2.0 and 2.2 diesel engines, and the pump specification can vary between these. Always give the breaker your full registration or engine code to make sure the pump they supply matches your engine rather than just the generation.

Trim level alone does not affect the power steering pump — an LX, Zetec, or Titanium with the same engine will use the same pump. The ST220 carries a 2.5 V6 engine which may use a different pump spec to the four-cylinder models, so the engine is what matters here, not the ST badge itself; confirm against your registration with the breaker.

Diesel and petrol engines of the same capacity often use different ancillaries including the power steering pump, so you should not assume a 2.0 TDCi pump and a 2.0 petrol pump are interchangeable. Quote your engine code as well as your registration to the breaker, as this is the quickest way to confirm you are getting the correct unit.
