2018 with 3.6L and auto transmission.
History: About 4 months ago we had the radiator replaced under warranty because it had developed a leak. Ever since I often check the reservoir bottle to make sure the level is all good and it has been.
We just got back from a 3 week long trip where we drove from Raleigh NC to Flagstaff AZ, off roaded, then off to Moab, off roaded, then off to Ouray, off roaded, then back to Raleigh.
Total of about 4700 miles, lots of 7 to 9 hour days on highways but also solely off roading.
Altitudes went from 300 ft above sea level to 12,900 ft above sea level. Temperatures from 95 to 54 degrees. Temps in engine were always normal but actually jumped 10 - 15 degrees when it was much cooler out and at altitude. It's funny to be at 96 degrees in Moab and running 204 coolant temp and then be at 54 degrees in Ouray at 12,000 feet and be at 214 but that is because the engine is working much harder due to thinner air.
The question is: can any of this have had an effect on the coolant level. It has dropped 1/4 - 1/2 inch in the reservoir bottle where previously it remained CONSTANT.
I can not smell any antifreeze at all.
