Good evening.

You may have a thermostat that is stuck closed. If it does not open, no coolant will circulate and the motor will run very hot.

Make sure the electric cooling fan/s run when the engine gets hot.

If the engine is hot and the hoses are soft, you have air in the system. First make sure the cooling system is full when cold so be careful when opening the cap, let it cool back down for an hour or two first.
