How do you know it leaks? Fluid level drops or by puddle on ground? If puddle it may be from the overflow. May be overheating even if temp reads normal. Radiator cap may be weak and letting the coolant come out the over flow. Replacing cap "may" fix it. Answer 1 is not incorrect but, I will respond to the part of the question about running "cool" in spite of the leak. IF the temperature sensing and guaging system are working properly, then the "normal" reading is correct. If the leak is small enough, and ENOUGH coolant REMAINS in the cooling system, then that would allow for adequate cooling, and thus a normal reading. Also, if the leak is small, and by regular "topping off," you keep the cooling system FULL, then one would expect normal cooling, and thus a normal guage indication. j3h.

Is an engine coolant leak bad?
Yes, If to much leaks out this will cause the engine to over heat, smoke and or stall hence the name engine COOLant :)
What engine problems can occur if engine coolant leaks onto engine during thermostat repair?
If coolant leaks onto an engine it will cause no damage unless it leaks onto the alternator or into a wire harness connector of some sort. It is best to clean up leaked coolant as much as possible. It will smell a little when the motor is started. Leaked coolant on the ground is a danger to animals and children as it has a sweet smell but is very toxic.

What can I do for a 2001 Pontiac Grand Prix if the engine over heats and the thermostat has been replaced and a flush and fill done?
You can check your coolant reservoir cap for oil, check the oil cap for water, and check the seals around the middle of the engine for oil leaks. If any or all of these are present, there may be an intake leak and the intake gasket needs replaced.
Can head gasket leaks destroy an engine?
yes, especially if the leak is causing coolant to leak, you can run out of coolant. then overheat.
