anyone had 1 on here?

the car will go into the red after ticking over or driving it within 15mins,then i shut off so never been roasted

ive changed the water pump,thermostat,viscous coupling on fan,and bled the system to death with front end up high

thing is i really dont think its head gasket

it doesnt over pressure up,no leaks,no oil in water or water in oil

engine runs sweet aswell
