Thanks for responses.

Our Ur radiator fan occasionally gets stuck on, swift firm but gentle 'tap' of the thermostatic switch at the bottom right of the radiator sorts it out for a few months.
Not sure I understand the purpose of the tap. I confirm the switch is open circuit, which I thought was correct?

Is that the turbo engine? If so, has after run relay (324) which controls cooling after ignition is switched off.
No turbo on KU. There seems to be more info on the Turbo for some reason!

Sure it does not have 2 fan relays? One for speed 2 and one for speed 3?
No not sure. I'm only seeing one relay in the (rather confusing) Haynes wiring diagram. Where/what is the second relay?
I've got '214' in slot 2.
