The air release valve is a black plastic screw by the coolant refill cap, if you unscrew this slightly after you've driven the car, it will release any air if it has any (be careful of the steam). If this solves your problem you're very lucky. I think it's most likely your water pump needs reeplacing. I would suggest getting this solved asap as there is a very real danger you can get your engine head damaged if the temp keeps going beyond the normal.

There's two sending units in the intake. The little on with single prong at the t-stat housing is for the guage and the bigger one plastic connector is for ecm.
Your signal is getting grounded somewhere.

There is an air pocket in the coolant (upper engine underneath the manifold). Some GM manifolds have a defective design that allows the coolant to leak from underneath the throttle body assembly inside the manifold. This can contaminate oil (check for caramel milkshake color on dipstick), and cause air pockets to form underneath the sensor---thus the erratic signal.

it sounds like a possible head gasket problem,you can get the fluctuation from combustion gases getting pumped into your cooling system and creating gas pockets,i would suggest taking it to a shop and have them do a block test to look for combustion in the cooling system to confirm the problem,that way you will know for sure,if it comes up negative they can also perform a flow test to make sure there is no restriction in the cooling system such as a plugged radiator or a bad thermostat,hope this sheds a little light on it

Testimonial: "I bet you've hit on the problem ! Car has been "using " antifreeze for a couple years now, with no leaking anywhere. Lost through the head gasket ?"
