So got my coolant changed from the original too the 50/50 prestone coolant. He did a few system flushes to make sure everything got out of the system. the shop recommended id change it when I got all my fluids checked. i guess because people are having big problems when changing there fluids and mixing them up and messing up there Jeeps in my area from shops using wrong fluids. so I'm running now the 50/50 prestone I'm just worried if it can have any long term affect on my baby. I have been checking it I don't see any rust or any gel type substances it looks good
