I keep a jug of the Mopar coolant for our car. I have topped off the recovery tank twice, and the dealer has done the same. No leaks anywhere, it's dry as a bone underneath and on top.On my 2012 4 cylinder. 200, the coolant level in overflow tank keeps lowering. I can't find any leaks, and no coolant smell in the heater,no coolant in the oil,no white exhaust
That of course is possible. However when I remove the coolant recovery tank cap, I can hear the hiss from the pressure being released.It is possible that you have a pin hole. Leave a pressure tester on the system overnight.
