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.
Yes, If to much leaks out this will cause the engine to over heat, smoke and or stall hence the name engine COOLant :)
Things to check: Coolant level Heat and AC fuses Vacume leaks Actual operating tempurature of the engine.
Check to see if the engine coolant is full. Check to make sure that the engine is not running hot. The coolant circulates through the heater core, and if its not cooling the radiator it will not be able circulate to heat the vehicle
Coolant level may be low. Check for leaks.
First of all you shouldn't be using water, you should be using engine coolant. And to answer your question, your engine will over heat and you will not be able to drive. You can do damage to your cars radiator running with no coolant.
your heat comes from your heater core which draws heat from your engine coolant so if you have no heat and the blower is still running then there is a coolant level problem as in none which then would cause the mottor to over heat and quick
It cycles coolant through the engine. Heat from the engine is transferred to the coolant through a heat exchange. The heated coolant then cycles through the system to the radiator, where heat from the coolant undergoes another heat exchange, transferring heat from the coolant to the air which passes through the radiator. Heat will also transfer from the motor to the air forced over the motor by the engine fan.

lack of coolant, check for leaks.
usually running hot coincides with a lack of coolant. Low coolant levels will eliminate circulation of coolant through heater core. ALMOST END RESULT----NO HEAT
Actually, the heat regulator for the engine is the thermostat. It closes off the coolant when the engine is cold and circulates more coolant when the engine is hot.
yes in a way. block heaters heat the coolant in the block there for warming the block up. coolant heaters heat the coolant out side the engine like in the hoses and radiater. and when the coolant gets hot enough it opens the thermosate and starts flowing through the engine..The coolant heater should be hooked into the engine so that it heats only the engine and the heater core. If the coolant heater is trying to heat the radiator then it will not work very well to heat the engine, you would need a lot of BTUs to heat the radiator as it will shed all that heat to the air that is surrounding it.
