1991 ford escort 1.9 engine. I changed the thermostat but still have no heat. The temp guage doesn't go past "C". It will get heat very rarely and when it does, the temp guage will work. If you shut of the car, the heater will not work again. Any ideas that I can try that doesn't require pulling the heater core??

You are going to have to find where the leak is first before looking at the temp guage problem. I would pressure test the cooling system and look for leaks. check the heater core...make sure thats not leaking. make sure the engine oil and transmission fluids are not over full and milky. Good Luck
see if the radiator fan is it running even when the engine is at C or at heat
if its running when its at C the thermostat is not working properly
do you keep the windows open when you are driving can be a reason
as the car has a radiator in side also which gives you the heat
It is much more likely you are low on coolant or you have an air bubble trapped in the cooling system. You should bleed the cooling system to get any trapped air out and make sure it is full of coolant.
you need to get the thermostat changed. The thermostat controls how much coolant runs around the engine and sends signals to your temp gauge to indicate how hot the engine is.
if the thermostat is faulty it wont sent signals to the temp gauge and wont open up to allow coolant to run around the system. Your heating is run by coolant, behind the dash there is the heater matrix hot coolant runs into the matrix which gets blown inside the cab.
Fitting a new thermostat will fix all the heating and gauge problems. if your technical minded you can buy a thermostat from an autofactor (or ford, but they are expensive from ford). a garage will charge about £30-£100 ish for a new one.
remove the heater core lines the two hoses that go to the heater core, take a splice tube either metal our plastic your part store will have either one. take the splice tube and install it in one of the lines add some hose to that tube make the hose long enough to run out side of the engine compartment and on to the ground. take the other hose and install a flushing tee, hook up to a garden hose and trun the water on . what you are trying to do is flush the heater core , you are also looking for blockage off the heater core, if you little to no flow i would suggest replaceing the heater core
Your coolant system aint heating up like it should. Its your thermostat. You need to change it. its broke. There are four parts to your thermostat. You need to make sure that you get all four parts out. A thermostat costs about five bucks. Its an engine temp. regulator. If its broke your engine wont warm up at all. If it seizes shut, your engine will overheat. Your thermostat is broke. I Have the exact same car that I have been repairing for the last three months.
