Right guys got a cosworth radiator which is brand new. It stays cold temp gauge shoots up into the red also has a new thermostat. New head gasket the water pump is working as its flowing through the turbo and header tank. Tried bleeding the system with no luck. Also the car does not pressurise. Very strange problem. If anybody could throw any ideas my way it woyld be great. Thanks.

 

Is try taking the thermostat out and see if that sorts the problem

 

^^^^^ LEGEND mate i assumed that it was fine as its brand new it was ok so overlooked it. Nice and hot now cheers mate
