It should sit at 90 all the time - the stat and fan should regulate it at that temp.

It should sit at 90 (+/- the width of the needle) once up to temp - 5-10 minutes of driving normally in this weather - then stay there of its own accord. Once the needle rises barely its own width from its "normal" position, the fan would normally cycle in and out all day long - in traffic or just sat on the drive.

If you're putting the fan in before then, all you are doing is pulling hot air into the engine bay (through the rad).

If you temperature gauge drops to 80 with the fan on, then your thermostat is goosed.

got home fine in the end.

I think this may be one of those things thats so intermittant its going to be very hard to ever diagnose.

Will take it in to my mechanic this week anyway. Will look at fuel vaporisation issues and will possibly fit a fuel filter.

Thanks for help as always :)

I sympathise, it took me years to sort hot starting issues. I changed coil, ballast resistor, checked fuel tank breather, replaced fuel filter, replaced plugs, leads, new battery, new radiator, new fan and otter switch, etc etc etc. In the end my mechanic tested the (original mechanical) fuel pump and found it was faulty. Fitted a new pump and never looked back. Starts on the button every time now although I have no idea if the fuel pump was the main cause of the hot starting fault or not as so many other components were already replaced by then. As far as fan overrides and engine bay extractors are concerned, I think Jim King has some very good advice in his signature... "cure the fault not the symptoms".
