I know there are two coolant temp sensors. Can't seem to find them both. One is in the t-stat housing and in the block, right?
No need to drain coolant.
Rubber, plastics, wood,... non-metalic material is a bad conductor of temperature. Any and all hoses will not yield an accurate temperature reading.
It sounds to me that you may have a bad thermostat or a poor quality unit that opens early then closes then opens,... that will be my first place to look.
