OVERVIEW
The power steering system comprises a hydraulic steering gear, a power steering pump, reservoir and a fluid cooler on
petrol engine derivatives.
The steering gear is a conventional end take-off, rack and pinion power assisted unit, mounted on the rear of the
subframe.
Different power steering pumps are used on the TD4 diesel engine and the i6 petrol engine. A variable displacement vane
pump is used on the diesel engine to give improved engine economy. A fixed displacement vane pump is used on the
petrol engine to provide refinement and responsiveness. Both pumps have high flow rates which enhance the steering
performance.
Petrol engine vehicles are fitted with a fluid cooler to cool the power steering fluid from the fixed displacement pump.
