Engine overheats When a car or truck overheats idling, in town, on the highway, while towing, etc. it is important to find out the reason to prevent engine damage. First, with the engine cold, make sure the radiator is full of coolant; if it is low, fill it and keep the radiator cap off while the engine idles to insure all air is bled out of the system ( air trapped in the system can cause overheating also). Check the coolant level daily; if the coolant goes down without visible leaks, it may be a head gasket starting to leak which will also cause the heater to blow cold air due to the lack of available coolant. If the coolant stays full, but the car continues to overheat, the next step is to replace the thermostat in the engine and flush the cooling system if that has not been done over the last few years.Buy a thermostat at a parts store and a PRESTONE flush kit which has excellent directions on the package.After completing these steps and the vehicle still overheats, have your cooling fan sensor/switch ( if equipped)checked out to insure it is coming on. Water pumps are seldom the cause as they are mechanical and will continue to work until their bearings give out. Finally, the radiator itself is often the problem as it tends to build up corrosion internally which prevents it from transfering engine heat to the coolant. Remove it and have it 're-cored'. One of these steps will solve the problem.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.
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.

I would do a complete coolant replacement and have the system flushed. Also replace the thermostat, and radiator cap, which may very well be your problem. If you are loosing coolant and there is no apparent leak, then you may have a blown head gasket. This can do serious damage to the engine. Have this looked into ASAP.
Sticky thermostat. Replace it.
Check if the thermostat is working properly. See if the top of the radiator is very hot when the motor starts to overheat, if it isn't hot then chuck out the thermostat or better still replace it.
