Parts for your 2007 Ford Mondeo-Power steering pump

2007 Ford Mondeo power-steering-pump: purpose, care and replacement

Technical references including the Ford Workshop Manual (Mondeo 2007–, Section 211-02 Power Steering) and the Haynes Mondeo manual for 2007–2014 confirm the 2007 Ford Mondeo uses an electro‑hydraulic power assisted steering (EHPAS) system. That means it absolutely does have a power‑steering pump—an electrically driven hydraulic pump/module (often TRW‑branded)—rather than a belt‑driven pump. The pump-and-reservoir assembly typically sits forward of the left front wheel, behind the liner and bumper.

The pump’s job is straightforward: generate hydraulic pressure so the steering rack gets the right assist, especially at parking speeds. Because it’s electric, assist isn’t tied to engine revs, and it sips power only when needed—handy for both fuel economy and consistent steering feel.

Good servicing keeps the Mondeo’s EHPAS happy. Fluid is critical: it uses a central hydraulic fluid such as CHF 11S/CHF 202 that meets Ford spec WSS‑M2C204‑A2 (green in colour). Don’t top up with ATF/Mercon. Check level and condition at regular services, if it’s dark, aerated, or smells burnt, a fluid exchange is smart. Inspect for leaks at the pump, hoses and rack, and listen for whining under the bonnet—often a sign of low fluid, aeration, or a tired pump. Because the pump draws decent current, a weak battery or dodgy charging system can cause intermittent assist or warning messages, so a quick battery/alternator health check is worthwhile.

Replacement is very doable with basic tools. Typical steps are:

• Disconnect the battery (the pump has high‑current feeds).
• Raise the front, remove the left front wheel and wheel‑arch liner for access.
• Drain/contain fluid, disconnect hoses and the electrical connector, then remove the pump/module.
• Fit the new unit with fresh seals, reconnect, and refill with the correct CHF fluid.

Bleeding is simple: with the front wheels off the ground, ignition on (so the electric pump can run), slowly turn lock‑to‑lock several times, topping up fluid as bubbles clear. Then refit, road test, and recheck for leaks and level. No coding is usually required on these EHPAS systems, but scanning for stored steering or CAN‑related fault codes is good practice after any work. Budget a couple of hours for a tidy, careful job.

• Popular questions about 2007 Ford Mondeo power-steering-pump

Does the 2007 Mondeo use electric or hydraulic power steering?
It uses an electro‑hydraulic setup (EHPAS): an electric motor drives a hydraulic pump feeding a conventional rack. This gives smooth assist at low speed without the drag of a belt‑driven pump.

What fluid should go in the Mondeo’s power steering pump?
Use a CHF‑type central hydraulic fluid such as CHF 11S or CHF 202 that meets Ford spec WSS‑M2C204‑A2. It’s typically green. Avoid ATF/Mercon—wrong fluid can damage seals and the pump.

What are the signs the pump is failing?
Common clues are heavy steering at parking speeds, intermittent assist (especially with a weak battery), a high‑pitched whine, foamy or dark fluid, and dampness or leaks around the pump or hoses. Sorting voltage issues and fluid condition early can save the pump.
