Res is where it usually sits right on the hot mark. Still to warm to pop the cap. The temp normally goes to 200 and then drops to 180 and then climbs back to 200 and to 180 but today it got up to 240-245ish. I checked fuses relays and turned on a/c to and nothing happened until I unplugged my coolant sensor and the fans came on.

You coolant sensor is bad. Sometimes you get a bad sensor...this sounds like one.

Such a sudden increase in temperature. We need to know how much is in the radiator. And if you can, pop the throttle body hose off and peek inside for coolant.

Good its still under warrenty!

Coolant level is fine. Right were I put it.

Have to wait till tomorrow to look at the uim.
