Hi all. I recently had the thermostat replaced in my 1.8 petrol Mondeo, as the heater was taking ages to get warm enough, although the temp gauge climbs to 90 degrees fairly quickly.
The garage said that my radiator fan is coming on at only 89 degrees, which may show why the heater isn't great! The temp gauge doesn't change when the fan comes on either, as you may expect it to do.
Is there a combined sensor on these cars, as that could provide a reason for these faults, or are they all separate? ie Radiator fan sensor, coolant temp sensor etc.
