When I bought my first jeep 2 months ago, I noticed the coolant was lower than the "add " level, so I went to my local CDJ dealer. I found the coolant type from the user manual but when I told them HOAT, the guy in part dept. seemed lost. Eventually I bought a jar of Mopar coolant--pink/red--and mixed with tap water and filled the container.
I plan to drain and refill it according the manual, at 60 months.
