Water temp / fan switch questions
What is the max safe water temp you should see on a cossie?
I was stop - start on the motorway recently and temp gauge went up to the top of the N of the 'NORM'. It didn't go off the gauge but SECS was showing 98 deg C. I wasn't stopped long enough to see if it would have gone any higher.
Maybe a stupid question but what is the advantage of having an in-car fan switch? I assume that the moment the water temp goes above 89 deg or whatever it triggers at the fans will start anyway and not stop until it drops down again. How will having a manual switch make it better or is it just a case of switching it on earlier than the thermo switch.
Cheers.

98C and you are worried, about what, the temp or that the fans are not on yet ?
98C is not anything to worry about, running hot at this temp doesn't kill headgaskets or cause overheating, but std fan switch is rated 86C/77C, stu's alternative switch is rated 92C/88C.
The temp gauge cannot normally be relied upon to be accurate, mine gets just above N before fan comes on and I have set them to come on at 90C and cool to 87C.
