I got the coolant flushed in my 2016 Challenger 3.6L at 90,500miles in September of last year and I’ve driven 34K miles since then. I noticed over the months the coolant in the reservoir keeps getting lower. It’s now sitting just above the Min line when cold. Is that a normal amount of coolant loss in 10 months and 34K miles? I live in Florida where is always hot and humid. The car doesn’t overheat and there are no external leaks. I have NOT had to add more coolant at all in this amount of time but I will be topping it off with distilled water.

Recent personal experience.
Do you notice any bubbling going on near the top of the overflow tank ? If so, inspect the radiator cap gasket. If it looks compressed, replace the cap.

As mentioned above, when my son’s Challenger had bubbling inside the overflow tank, we replaced the cap and so far so good .
FYI- dealer wanted $ 41 for a OEM replacement cap that needed to be ordered. RockAuto wanted about $ 18 for the same cap and local parts store wanted about $ 8 for an aftermarket one.
