Tomorrow I’m going to buy some antifreeze and add some til it is between the minimum and the maximum line. I will then run the car to see what happens. Heat works. Radiator gets hot the fan is working . The fan turns on when the AC goes in and fan shuts off when AC is shut ( when engine is still not too hot) . I also tested the the heat test Erving the car at 1000 rpms. Temperature goes down but fan stays in. I also touched the hoses and the hoses are hot ( I assume water / antifreeze are flowing through them.
If adding antifreeze doesn’t solve it , I’ll bring it to mechanic and I’ll let you know what they find. I will explain bleeding the system for air .
Thank you so much for your help. You really explained everything thing to me and I truly am grateful. Have a wonderful evening
