Hey how are you
I m Sorry to hear about issue you having
1- we are running hot , is the fans working have you checked sitting at idle ?
2- have you checked coolant level , is there any leaks under it ?
3- until you get to a repair shop, you need to add coolant to it , check when cold not hot. and drive it until it start to get hot ,when pass the middle mark on gauge , pull over and let it cool down completely and check coolant again ,if low add.then drive again,keep watching temperature very important or you will have sever damage like head gasket
4- there is several possibilities here , from low on coolant , thermostat ,radiator,belt , water pump, to a worst issue as blown head gasket
Please let me know
