== == 1) System overfilled (too much coolant in tank)
2) Overheating.
3) Faulty radiator cap (doesn't hold pressure)
4) Hole in tank.
5) Residual air pockets in cooling system due to improper filling procedure.
6) Pressurized combustion gasses in cooling system from damaged engine or gasket.
The ONLY reason this would happen is the head gasket.
Or cracked head or crack on the block.
if the vehicle still runs good then there is a chance that you are filling the ank too much or the cap is bad.
On the cylinder head close to the thermostat housing.
It should be filled to the "Full" mark on the side of the bottle.
The thermostat is not opening up enough,
the sensor is located on the thermostat housing
To remove the overflow bottle of a ford escort 1993 you need to: 1. Unbolt the PS fluid reservoir and move it out of the way. Don't take any of the hoses off. 2. Disconnect the electrical plug on the coolant overflow bottle. 3. Remove the overflow bottle mounting bolts. Lift the bottle, disconnect the overflow hose and take out the overflow bottle.
thermostat housing on the side of the engine block
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.
Actually, the heat regulator for the engine is the thermostat. It closes off the coolant when the engine is cold and circulates more coolant when the engine is hot.
Follow the top radiator hose from the radiator . The hose connects to the engine coolant thermostat / water outlet assembly bolted to the engine . The engine thermostat is inside the housing
THATS WHAT THE OVERFLOW/EXPANSION PACK IS FOR. WHEN ANTIFREEZE/COOLANT BEGIN TO BOIL IT EXPANDS AND IT NEEDS A PLACE TO GO. THERE FOR IT GOES IN TO THE OVERFLOW/EXPANSION PACK. THIS PREVENTS DAMAGE TO THE ENGINE/RADIATOR AND OVERHEATING. THERE IS ALSO THE POSIBILITY OF A MALFUNCTIONING SENDING UNIT/GAUGE.
cool hello
1.) Low Coolant, 2.) Bad Coolant, 3.) Bad Thermostat, 4.) Worn Water Pump, 5.) Lead-Foot Problems
