Hi... (trying copy/paste my problem in here too)

Bought a Mondeo nearly 2 years ago, and it drove "cold"... changed the thermostat, and the car became very hot, not boiling, but very hot (3/4 scale)

I then changed ther waterpump with a new one 8metal impellas)... but the old one was as new! The engine still got hot, and I thought the new thermostat was faulty, and I changed it once again... still the same. the fans kicks in when almost "medium" warm but is can cool it dont to cut the fans again (in other words they run constant) and cant cool down if rise the speed to get more air trough the radiator.

Can it be crappy thermostat (triscan 88 degree) or is it a common problem with these engines???

Can this thermostat be fitted "upside down"???

Radiator is relativly new.

Lost of coolant in the header. Coolant is nice and clean, and the los of water is extremely little.
