I had no heat in my escort either. A new thermostat, cooling system flush, new heater core, another new thermostat, ect. but nothing worked. Still only slightly warm air from the vents. The thermostat housing has a thermostat bypass in it. This bypass is always circulating coolant through your radiator. I plugged mine off with a thermostat gasket and now my car heats and blows hot air with no complications. Good luck.

Why does Thermostat gauge go on and off What is wrong with it in my 1993 ford escort lx?

There could be several things wrong with the system that the thermostat gauge is connected to. You could check to see if the gauge is working correctly. If the gauge works fine, then it could be the housing that the thermostat is mounted to. It could also be a faulty bypass valve near the thermostat which prevents the engine from heating up. Check these places to see what may be wrong with your escort.

How can you tell if thermostat on 95 ford escort bad?

If the engine is taking a long time to warm up or the gauge registers low heat the thermostat probably is stuck open and needs to be replaced. If the engine runs hot check the temperature of the upper radiator hose. If it's not hot the thermostat is stuck closed and should be replaced. If the upper hose is hot it means the thermostat is open and working. Cooling problem could be restricted radiator.
