2006 Chrysler Pacifica won't hold coolant, no apparent leak

Asked by Sam Dec 19, 2016 at 08:21 AM about the 2006 Chrysler Pacifica FWD

Question type: Maintenance & Repair

I have an 06 Pacifica that needs coolant every 2 days or so.  I have yet to find
a leak, I've even parked over cardboard to check for results and have been
unsuccessful in finding any amount of fluid that would be obvious of a leak.  
When it is low on coolant the heat will not operate, and the cooling fans will
become much louder than normal.

The coolant is either going out the tailpipe or into the oil pan via the head or intake gasket, or draining to the ground when the car is running via the degas bottle overflow (blocked cooling system, blown head gasket), or via the heater box condensation drain (leaky heater core).
