my coolant needle is going crazy... it's reading in the middle, then getting to hot, and coming back down.

just now on my drive back home, it went to hot, and stayed at full hot.

my auto meter water temp gauge reads 100*F the whole time.

on my way, it actually fluctuated from 100*F, to 150*F, back down to 100*F

This problem recently started happening. I bled the system already when i swapped in a new rad, and it has been operating at normal temps for a while, until now...

any idea what's wrong?
