You could try knocking on the bolt, that would create some vibration(to
remove dust or rust) and would make the disassemblie easer.

Don't applie too much tork when unscrewing the bolt.

You could change the radiator cap, that doesn't cost much but it help to
keep the pressure in the system.

Good luck!
