The 2.5-liter Ford HUWA turbo engine was produced at the Swedish plant from 2006 to 2010 and was installed in the first generation of the popular S-MAX minivan, but only before restyling. Such a power unit is essentially just a modification of the Volvo engine with the B5254T3 index.
DURATEC ST/RS family:
2.0 L – ALDA, HMDA;
2.5 L – HUBA, HYDA, HYDB, HUWA, JZDA.
The engine was installed on:
- Ford S-Max Mk1 in 2006 – 2010.

Disadvantages of the HUWA engine
- The weak point of this motor are the valves and couplings of the phase control system;
- Also, many are faced with lubricant consumption due to clogged crankcase ventilation;
- For the same reason, oil often presses through the front camshaft oil seals;
- Carefully monitor the condition of the timing belt, as when it breaks, the valve bends;
- On a run of 150 – 200 thousand km, the fuel pump and turbine often require attention.
I’m not sure but I think “Ford S-Max Mk1” was meant instead of “Ford S-Max Mk4” in the “The engine was installed on” section.
Thanks!
