I had my radiator hose bust, naturally my temp went up pretty high but I changed the hose and it was fine. I was trying to figure out if when the temp goes up like that if its possible that the thermostat got so hot it was damaged. I also only have pretty much all water in the radiator, which I'm changing back to antifreeze today. The temp has been fine, but when I got it on the highway after about 70mph the temp started to jump. Anyone have answers for me I'd really appreciate it
