Many times after a Jeep cooling system is repaired, air bubbles trapped in the system will cause a overheat situation. If it is a 4.0l, with the engine cool remove the heater hose that is connected to the thermostat housing and fill the cooling system with the engine off. When coolant starts coming out of the engine side the system is almost as full as it gets.

Your thermostat is stuck closed. you will need to replace it. The thermostat controls the circulation through the radiator - when the engine heats up the thermostat is meant to switch circulation from just-engine to engine+radiator. Sounds like this isn't happening.

Your 1997 escort only heats when you are not driving?
Chances are your thermostat is stuck open. Your cars thermostat sits in a coolant passage. When the car is running your coolant begins to heat up, and at a certain temperature your thermostat opens up and lets coolant flow to the radiator to dispel the heat of the engine to the air. When your thermostat is stuck open, instead of the coolant staying in the engine until it heats up it is constantly circulating through the radiator transferring heat to the atmosphere. When your cars sits still it heats up because the amount of air passing through the radiator is minimal, but as you begin to drive the air flow is increased.

What happens when the thermostat fails?
When the thermostat in your car fails it usually fails to open which in turn does not allow radiator water to pass through the engine and cool it, so the engine over heats.
