OK...maybe this is a little OCD, but I noticed that my engine coolant level dropped about 1/4" over the last 1000 miles, and there is no evidence of leakage. My 2-door JL has the 3.6L engine, and I have been driving a 50/50 mix of highway and city miles at an average temperature of 80 degrees Fahrenheit. Although I've seen this same thing occur in some older cars, it never occurred in my '99 TJ, '80 CJ-5, '92 Bronco II, and other vehicles....coolant levels remained rock solid, and I would have thought the same would be true in a brand new Wrangler. While I'm not terribly worried, it would be nice to know if others are experiencing the same thing. Appreciate your observations and feedback.
