1996 Acura TL Question: why my 1996 acura tl 3.2l temperature gauges goes up to hot then fall down?

Changed sensor and radiator -
Answer 1
When the guage drops to cold are you still getting heat inside? is it randomly going up & down quickly or is it gradual? the guage may be faulty or there may be air trapped in the system . when you changed the rad. & sensor , did you change the thermostat? Is it functioning properly. -
