Vehicles with 2.0L or diesel engines
The power steering system uses a rack and pinion type, variable ratio steering gear. The power steering pump is belt driven on all model variants and the power steering oil cooler is of a wire bound tube type and is mounted in front of the radiator.
Vehicles with 2.5L or 3.0L engines
The power steering system uses a rack and pinion type, variable ratio steering gear with servotronic steering assistance. The power steering pump is belt driven on all model variants and the power steering oil cooler is of a wire bound tube type and is mounted in front of the radiator.
A variable steering rack ratio reduces the amount of turns from lock to lock to improve parking maneuvers without loosing any steering feel at higher speeds.
The steering assistance decreases smoothly at a calibrated rate to increase the steering efforts required as vehicle speed increases. The steering efforts are controlled by the servotronic valve (actuator) position, which in turn is controlled electronically by the servotronic ECU housed in the instrument cluster.
Absolute cleanliness must be observed when replenishing the fluid or dismantling any part of the system. New fluid from a sealed container must be used.
Note. If the steering gear, pump or cooler are being replaced for leakage or noise related issues and there is no evidence of fluid contamination, there is no need to replace the reservoir.
In some cases where the fluid clearly contains particulate matter, and the system continues to function, flush the system with fresh fluid and replace the reservoir, as there is the possibility that the reservoir internal filter may be damaged or faulty.
