Hello !! Have the following problem with my Ecort, 1.8L, 16V, Zetec: The car is built in 8/95, and has 77 KW. For a few days the temperature indicator goes into the red area. Cooling water I checked. Since the radiator fan did not sprung, although the indicator is in the red area, I replaced the thermoswitch of the fan. Now the fan goes but the temp. is still in the red area. Before the temp. indicator never went beyond the middle area. The cooler hoses are all equally warm (Heiss). The balance tank is hand warm. Now I have the idea that possibly the temperature sensor is def.. Now my question: -Where is this. Have a plug on the thermostat housing, it can be this one? – How can I test this if there is a def.? – What can it still be about? Need urgent help !!! Thanks in advance !! mfG AXT
