hey everyone
02 camaro 3.8. recently the coolant temperature gauge has been going in and out on me and recently just doesnt even move anymore from the resting position even after driving for a bit. i figured the coolant temperature sensor was going bad. i replaced the sensor today and that wasnt the issue. so i went further and replaced the thermostat and that also wasnt the issue, the guage still didnt move.

the ses light is on and im pulling the code p0128 which says coolant temp below thermostat regulating temperature, also the fans are on non stop. after i changed the thermostat i filled the radiator up with coolant, let it idle for a bit, and nothing happened...top radiator hose is soft also. i figured the thermostat would open and begin to let coolant flow. id appreciate any help from you guys, just want to get this fixed because i dont want to drive it im not sure what kind of damage it could do to the motor if coolant isnt flowing. thanks.
