ive changed thermostat, all hoses, flushed radiator and made sure no leaks. why does it ontinue to overheat
Water pump might be no good.
Even through you have flushed the radiator it may still be plugged, that old you may a good core and maybe able to have it rodded out, if not then I would replace the radiator.
Make sure all spark cables are connected to the right sparkplug. A cross wire like 4 and 8 will overheat even enough to make your fenders hot.
