My '95 Daewoo engine has recently been cutting out when I have been driving slowly and it has been hot (ie in the City or up a long steep hill). It restarts when it has been left for about 20 minutes and so appears to be due to overheat. However, the temp gauge does not go beyond halfway and there are no other obvious signs of overheating. I have fixed a faulty cooling fan but am worried its something more serious?

From what you are saying that your engine is cutting out and it will start after sitting for 20 min, sounds more to me like you have a clogged fuel filter, Try changing the fuel filter. I do not suspect anything is wrong with your cooling system, being you see no symptoms, so your cooling system is fine.

Have you ever tried to put coolant into the radiator when it is cold. You need coolant to cool. From what you describe you could easily have done damage to the engine. You need to take the car to a reputable garage and have it checked over.

How much of the coolant space in that car's engine cooling system is taken up by water/1,2-ethanediol-based coolant, and how much of the coolant space is taken up by water vapor, nitrogen, oxygen?
The latter three substances are quite affordable, and find their way in, when the expensive ones find their way out. The cheap ones do not conduct heat away from the car's engine nearly as efficiently as the earlier-named substances do. In addition, I suspect that the "prime mover" in that car's coolant system was designed to move liquids, not vapors, and N2 and O2 are liquids only at VERY COLD temperatures. Convection is key. If it don't flow, it don't conduct the heat, so your engine gets to keep the heat.

ok first off, "half way" is too far. secondly the heat sensor it's hooked to may be damaged or malfunctioning. third, install a water thermostat that has a lower temprature rating than is recomended for the car (say 10-20 degrees lower). that way it lets more water into the engine at a lower temperature, not letting it get hot in the first place.

It could have something to do with the thermostat.
You might even have a cracked seal.
