Here is a guide that will help with the basic things we need to start with:

https://www.2carpros.com/articles/engine-overheating-or-running-hot

Major items to focus on are coolant level and quality. Cooling and A/C fan operation. Do they both come on when the A/C is on?

Then we are going to need to check the thermostat operation. Put it hot water and make sure it completely opens.

Let me know what you find and we can go from there. Thanks
