First I have a 2010 F150 superSCREW xlt (for sale 19k miles)

I had something weird happen... came to a stop. The coolant light came on, I think oh crap it is over heating but the Guage was completely to the left like itwas ice cold, the other guages were fine. Turn the key off and started it back up and everything was back to normal.

The only thing that happened is I came to a hard stop, not hard as in everything flying to the front seat type of thing but harder than normal.

Anyone else had this happen?

 

Has it done it again since that one time? It's strange for sure but maybe a loose wire on the coolant temp sensor?
