SOURCE: Temp gauge on dash fluctuates up and down and stays at times red.
Check your cooling fans to insure they are working to cool the radiator...
I’m happy to assist further over the phone at https://www.6ya.com/expert/joe_a3369546f8067589
SOURCE: while driving late last night,
DID U CHECK THE STARTER TO SEE IF IT IS GOOD!!!MAKE SURE THE WIRE IS CONNECTED REAL GOOD TO THE STARTER TOO!!! B/C IT WILL DRAIN YOUR BATTERY!!! THE SAME WITH THE ALTERNATOR IT TOO WILL DRAIN YOUR BATTERY!!
SOURCE: antifreeze ts boiling back into reservoir.
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 ?"
SOURCE: 2004 cheverolet impala 3.4L engine
Sounds like you have an air;lock in your cooling system.Try placing a bleeder on the return hose to the heater core ........looks like a small tap

If
all voltages checked ok, then most probably its faulty instrument cluster board
on which gauges are connected. Yes if cluster circuit board looks ok, then also
it can be faulty. Somewhere there is minute short or burn on board then such
problem arises.
Also
check the fuse box. One under hood and other under dash.
Inspect
each and every fuse and see if all are fine or not.
