Jaguar X-Type Sedan and Estate (Wagon). Service manual — part 107
6. NOTE: The suitable funnel should have the a capacity of 4 litres and
O-ring seal
• NOTE: The suitable funnel must be tightly sealed to the power steering
fluid reservoir to avoid fluid leakage.
Install a suitable funnel onto the power steering fluid reservoir.
7.
W ARNING: Do not work on or under a vehicle supported only by a
jack. Always support the vehicle on safety stands.
Raise and support the vehicle with the wheels just clear of the ground.
8. CAUTIONS:
Steps 8 and 9 must be carried out within 2 - 3 seconds of each
other. Failure to follow this instruction may result in damage to the power
steering system.
Be prepared to collect escaping fluids.
Using the suitable funnel, top up the power steering system with the
specified fluid. Make sure the fluid level is maintained at two thirds full
in the funnel.
9. CAUTIONS:
Be prepared to collect escaping fluids.
Do not allow the power steering fluid level in the power steering
fluid reservoir to fall below the minimum power steering fluid level. Failure
to follow this instruction may result in damage to the power steering
system.
Make sure the engine is switched off as soon as the full 4 litres of
power steering fluid has entered the power steering fluid reservoir.
Flush the power steering system.
Start the engine
With assistance turn the steering slowly lock to lock 3 times at
approximately 1 revolution every 5 seconds.
Continue to flush the power steering system until 4 litres of power
steering fluid has been added to the power steering reservoir. This
should take approximately 30 seconds.
10.
CAUTION: Be prepared to collect escaping fluids.
Remove the suitable funnel.
11.
CAUTION: Be prepared to collect escaping fluids.
Remove the suitable pipe to the power steering return hose.
12.
CAUTION: Be prepared to collect escaping fluids.
• NOTE: Note the orientation of the clip.
If a quick release coupling is fitted to the power steering return hose,
connect the power steering fluid return hose to the coupling by installing
the clip.
13. Install a new power steering fluid reservoir. For additional information,
refer to: (211-02)

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
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.
contamination, there is no need to replace the reservoir.
