Heater core could be clogged-up or leaking-Are you overheating? And how long has this been happening-coolant gettting low-could be leaking somewhere externally or being burned in the combustion chamber-Pressure test the cooling system

Car temp=engine temp?
The heater core is a heat exchanger just like the radiator. It removes heat from the coolant flowing through it and gives it to the air passing over it. So, a drop in engine coolant temperature is normal.
Does antifreeze build up in the overflow bottle when the heater is off? Do the floorboards of the vehicle get wet? Can you smell coolant?

The car has never overheated. Coolant smell every once in a while. No collant is in the oil. If there was it would turn an unusual chocolaty color correct, and be thick?

As my esteemed colleague stated, we recommend having the cooling system pressure tested. It's a fairly closed system, so the levels shouldn't fluctuate much, if at all.
