Why coolant leaks when engine is off but heat wont work when engine running?
The heat is not working because you are very low on coolant, probably because of the leak. Seems to me that it should leak worse when it is running, so I am going to assume you are talking about the coolant overflowing the reservoir, in which case goes back to you being low on coolant and the engine boiling the coolant.

Buick lacross low on radiator fluid but cant find leaks and not leaving any puddles?
Clean the engine and check it again while its hot and running. Maybe the thermostat gasket? I fixed one of these yesterday. Rubber gasket had swollen and torn. Coolant tends to evaporate where it leaks, so you'll only have a puddle if the leak is big. Small leaks tend to stop when the motor is not running, since the water pump increases the pressure in the block significantly.
Have a 1998 Chevy Cavalier coolant leaks from somewhere near the front of the engine when cold but not when running or hot?
You may have a bad head gasket and it may be leaking from that. Why when cold i dont know, but if you are losing coolant it may be the head gasket.
