Help my cars overheating. Its full of coolant and ive replaced multiple parts. I've replaced the thermostat, water pump, radiator, and all new hoses.

 

Next step would be rent/borrow a coolant pressure tester from the parts store. Pressure the system to about 12 psi ,start the engine and see if it builds more pressure. It would also show where a coolant leak might be coming from. If it builds more pressure that would indicate a sign of bad head gasket or a cracked cylinder head.
