Fan not cutting in

[CL1O NUT]

My fan isn't cutting in, would this just be the temp switch? I think I replaced the fan motor last year so doubt it's that.

Anyone know of how to find out what's wrong with it? How much is a new temp switch, where is it, and how easy it to replace?

Cheers

Temp switch is screwed into the rad - run a live to the motor to see if the fan hasnt siezed. Check the thermo stat and also the water levels.

ah you're a star cheers. I do have a slow water leak somewhere and I'm topping the water once every 2 or 3 days at the moment, could that be effecting the fan then?

and also I know what the temp sensor thing looks like now but what does the thermostat look like?

Thanks for your help.
