93 Ford Escort having cooling problems

I top off coolant reservoir and radiator and car runs fine. After driving the car I will begin to hear and see steam from under hood. Temperature gauge inside car does not indicate overheating until water is totally boiled out of radiator. Also, the overflow/reservoir is still full. Any ideas? This doesn't seem like a thermostat problem to me, as car would overheat quickly. Water pump?

I had a similar problem with my car. Turned out to be the connection to the fan that was faulty - the mechanic circumvented the problem to ensure the fan came on immediately upon starting the car. This allowed me to keep the car moving without fear of the engine overheating. My auto mechanic then just replaced the faulty piece (not too expensive if I remember correctly). Mya be this. Hope so!! :-)

Look and see if you can identify exactly where the steam is coming from.
