Ummmm so I’m stumped beyond stumped:
08 Jeep. Replaced the radiator in May right before power tour as I said last night. At the time I did a quick complete coolant flush. Twice. Refilled with Prestone brand antifreeze. Well the radiator split yesterday right? Went to swap it with new one about an hour ago, took forever to get the radiator cap off. found the radiator full of ice and frozen solid…. It’s 11 deg F out. Clear ice on top, bottom hose is semi frozen slushi green, like the coolant separated or something How the hell is that even possible?!?
