Jaguar X-Type General Maintenance

Windscreen (Windshield) Washers)

Not a difficult job, to maintain these but if they are not used for a prolonged period they can block, especially when using some of the modern detergents.

The most likely blockages occur in the Non-Return ValvesJaguar do not specify a part number for these , or in the spray heads (jets)Jaguar part number C2S16868 , themselves.

These are very expensive parts, the non return valve can be changed for a generic unit, but the spray heads should be replaced with Jaguar parts.

Repair

If the units are very badly blocked its worth removing them and soaking in warm soapy water, however a quick on-vehicle repair can be done as follows:-

For faulty RH Side Jet
Disconnect the RH pipe at the exit to the non-return valve. Then remove valve from the pipe.

The direction of flow is clearly indicated on the top of the valve.
Using an Air duster, blow though the valve in the direction of the flow. Then also using the air duster blow though the pipe that was connected to the exit of the valve (goes to the other jet).

Re assemble the unit ensuring that the valve is replaced with the flow in the correct direction. Fill the washer bottle and test.

For a blocked LH side jet
Disconnect the RH pipe at the exit to the non-return valve.
Disconnect the LH pipe at the exit to the non-return valve.
The direction of flow is clearly indicated on the top of the valve.
Using an Air duster, blow though the pipe and valve in the direction of the flow. Then also using the air duster blow though the pipe that was connected to the exit of the valve (goes to the LH jet).
