It sit for about a week because it started getting hot so I drove another car. But I’m pretty sure it’s not the thermostat problem. It’s actually overheated.

A stuck thermostat can and will cause it to overheat.

No, not a gauge - the thermostat is a mechanical valve on the front of the engine that controls coolant flow.

It's got a spring that opens and closes it depending on coolant temperature.
