Just checking my fluids before a trip and the coolant looked low-ish. I haven't sweated this stuff much yet since I got the Jeep new and it's only 2-3 years old. It's a 2011. The coolant reservoir just says "min" and "max". Is that hot or cold? The level is below min when cold, but if it were actually at max cold there'd really be little/no room for expansion, so I guess it must mean hot?
