3 In either case, remove the pump by disconnecting its electrical connection and pulling the pump upwards out of the reservoir orifice. Be prepared for loss of water from the reservoir.

4 To fit the pump, locate a new seal in the reservoir orifice and push the pump into it so that it is firmly home. Reconnect the electrical connection.

From 1986
5 From early 1986, the washer system is modified and now has a single reservoir and pump located in the engine compartment, with a plastic tube to the rear window incorporated in the rear wiring loom. The wiper motor switch incorporates two sets of contacts which energise the pump with opposite polarities, causing rotation of the pump vane in two alternative directions. Using in-line non-return valves, water is directed either to the windscreen or rear window according to which direction the pump is rotating.
