I've a Fiesta 1.25 Zetec-SE 'S'-reg..... problem is that the temperature gauge seems to be permanently stuck on cold. Ever so often it may move up so it's just bordering on the 'normal' section, but then usually moves back into cold again.
The engine itself seems to be warming up OK, with hot air blowing through the dashboard vents within a few minutes of starting up. From this I'm assuming that the thermostat's OK, and it's a problem with the engine's temperature sensor/sender.
Am I correct in reaching this conclusion, and if so where is it located and how easy is it to replace?
Thanks for any replies.
