Today on my way home my coolant and oil temps jumped to 224. Now i have been having some funky issues lately. AC randomly sprayed freon everywhere(not fixed), red lighting bolt coming on and off(fixed), heated sseats not working(not fixed)... so I'm fighting for my life against the gremlins. So I pulled over, let it cool then checked my oil and coolant. All full. The overflow tank was a little low so I put a little in there. I got in and finished my commute and the numbers went right back up!? What could it be? Themostat? Can't be water pump. That was replaced last year

 

Do temps come down if you sit and idle??
