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.
Have you checked the cars thermostat?
Bad gasket or overheating of the engine. Check cylinder compression and seals.
sounds like you have a blown head gasket
Most likely because you have added to much coolant when it was cold.
Engine coolant.
Coolant is getting into the ATF possibly through a hole in the oil cooler

Why is Coolant overflowing from the cooling tank at times and drains down into the left rear well?
Coolant is used to keep an engine in a vehicle at a temperature safe for operation. If no coolant is in the reservoir, an engine will not start.
The engine coolant temperature sensor is usually on the front of the engine. The coolant temperature sensor will be in the vicinity of the thermostat housing.
