Question about 1999 Ford Mondeo
We replaced the switcher unit (I think that's what you call it) and now the car has immediately gone onto the red even though the engine is cold! Any ideas please because this is ridiculous and becoming a real pain in the you know what!
Some cars have more than one sending unit for the temperature. You probably bought the wrong one.

Did you run the engine with rad cap off & heater (not defrost) on while topping up the coolant. If not, do it & let it run that way until your rad fan comes on & off about 3 times, then top rad up to a inch or 2 from top, and put cap back on, & check level in return bottle.

I doubt if it is the temperature sensor if the gauge is working. Check to see if the fans are coming on when the engine is hot. The fans have two speeds and should come on in low speed and change to high speed as temperature gets hotter or when air conditioner is turned on. If they are working correctly. I would guess the radiator is partially plugged up between the air conditioner condensor and the radiator. These cars are bad about getting dirt, lint, and what ever trapped in this area.
