my temp gauge decide to just go all the way past hot today (max) while i was driving back from the freeway. (stopped at greenwood traino for little brother) it clearly wasnt right, as the car felt normal, and had been under very little load, as traffic was pretty heavy.

what would have caused this?

any ideas or solutions would be greatly appreciated

edit: also its been like a top of 16*c today and raining.
i let my car idle in my garage for around ten minutes, just curious to see if it would go down, and after about ten minutes it went down nearly a quarter?
