My 308 1.6 150 bhp radiator cooling fan is coming on but temperature gauge is reading normal at 90C. This happens usually after a 10 mile journey on dual carriage way at about 70-80mph. I usually hear the fan ON when first stopped at built up traffic entering town. I'm not sure when fan starts during the 10 mile "fast" journey. I tested car on driveway at idle and waited for temperature to go to stable at 90C, fan did not come on. Can you help?
