Make sure you are using the correct type of antifreeze. Mixing some environmentally friendly antifreeze with older type "green" can cause gelling. Some antifreeze will gel with age. You may need to flush the entire system and replace with the correct type for your car.
ran in to same problem with 93 escort. went to ford escort owners association (feoa.net). my problem turned out to be a vacuum leak. the forums will help narrow down problem. there is also a way to check and find out error codes on the site.
check coolant sensor float most common problem.
add 50/50 mix of coolant and antifreeze or buy premixed from local auto parts supplier
I was having the same problem with my daughter's escort. I replaced the cam position sensor and the problem stopped. Advanced Auto Parts will check the computer to find out the problem for free.

thermostat, or water pump are the most likely causes... try the thermostat first... that is the cheapest and easiest one... if that doesn't solve the problem, you've narrowed it down to the water pump
The Check Engine Light has come on because the computer has detected a problem with the emissions system. It has nothing to do with the coolant. Take it to a trusted professional and he will scan the computer with an OBD2 scan tool. He will use the fault code as a guide to determine what the problem is. also if you had recently messed with the engine as in unplug something and turned the car on the the light will be on for a few days but eventully turn off
Check the alternator. Put a new battery in it or check the alternater.
Check the condition of your coolant, also noting the level of it. Without coolant, your car will run hot, and the water pump will not get lubricated and may cause a failure.
Your reservoir may be low. This will trigger the coolant light. It is often a malfunctioning sensor and nothing is actually wrong with the cooling system or coolant. It can be easily replaced. Alternatively you can leave it, but monitor your engine temperature and coolant level.
the fans are operated by means of a series of relays which are turned on or off by the engine computer. the engine coolant temp sensor that sends its signal to the engine computer is what indirectly turns on the fans. if there is no check engine light for a coolant temp. sensor code, the problem lies in the fans themselves, or the relays and related wiring.
Could be many answers to this problem. Starting with worse-case and going to best case scenario... Check coolant level. If you've serviced the coolant regularly and coolant is an off-color or is contaminated, then run a compression test. If the level is low, it could be an internal engine leak or external leak. (hopefully external) If coolant checks-out, then try replacing the thermostat. Sometimes the gauges will read incorrectly and so that's another possibility.
check your coolant temperature sensor
