I may request more information or provide an answer momentarily. Just a moment. Are the cooling fans working?
Automotive Expert
Are you using the gauge as an indicator of engine temp or using scan tool to monitor the DATA.

No I have not
Automotive Expert
Okay. Is the cooling system boiling over into the overflow bottle when it overheats? I just want to confirm that the vehicle is in fact overheating.

I honestly don't know, I checked for leaks or loose hoses the coolant base itself is full. I added coolant to the backup
Automotive Expert
Got it. I think the next thing to do here is take a manual reading of the cooling system temperature to verify the gauge is accurate. If the vehicle is in fact overheating, this may be a [water pump](/topics-water-pump/) issue or a [radiator](/topics-radiator-chevy/) issue. If the vehicle was severely overheated, there may be an issue with the cylinder [head gaskets](/topics-head-gasket-chevy/).

I'll try that thanks
Automotive Expert
You're welcome.
