I started driving and the temp warms up slowly like usual, but the needle goes up to the right side of the '0' in 210. Then redlines. I turned off the Jeep, let it sit for 2 minutes and restarted. The temp needle stayed at the right side of the '0' in 210 the rest of the way home.
There are no leaks. I have no loss of fluid, reservoir tank is full.
