I was on a nice coastal drive and a pack of deer popped out in front of me and I hit one of them. The damage is surprisingly limited given the fact that I killed a giant deer. My radiator on the passenger side was damaged and it started to bleed out. I wasn't far from home so I drove home and the engine oil temp started to get pretty high just as I got home. The z51 has impressive cooling, the fans were working their magic, it was cold outside too. My question is that we have had a storm now and I doubt I am going to get another nice day for a while. Is there any problem with leaving the thing sit until the spring with no coolant? I know very little about car mechanics and just want to double check. I won't be running it and will flat bed it in for repairs. If I top up it will just bleed out again. I would guess once it's fixed they will flush the system?
