Hi guys, I have a mk4 fiesta 1.25. When I turn the ignition on the temp gauge goes straight to hot, without the engine running with a stone cold engine
It's not overheating it's more of a electrical problem. Still does the same if I disconnect the temperature sensor on the thermostat housing?? Please help it's driving me insane!!

could simply be a fault on the speedo cluster which is common and the whole unit 2nd hand is peanuts and easy to change,

I'd try that^ Does sound just like a dodgy speedo cluster.

Not sure about the 1.25 but the 1.3 had two coolant sensors, one was the switch for the fan the other was a sensor for the gauge and engine management
