When I disconnect the temp sending unit from above the radiator with the car ON the temp gauge stays halfway up. When I ground it out it doesn't move, but after awhile the annoying buzzer starts going off. Does this mean the temp gauge itself is broken?

 

that is the sensor for low coolant light and buzzer im pretty sure...the temp sensor is on the block by the plugs...

 

d'oh. stupid.... Guess i will do the check with the actual sensor.
