ive replaced radiator and the expantion tank refilled the colant and attemted to bleed the air by squeezing the top hose while the car is hot and the tank cover off
Unless your squeeze was able to get any air all the way through your system and back to the radiator it was not enough to bleed any air out. Try again by running the car to have the air pumped out (open the radiator cap when cold, insure coolant is to the top, run the car and watch the fluid level making sure the level stays above the upper radiator hose level) Air in the system will cause the fluid level in the radiator to drop and you need to be ready to add more when it happens). Good luck.
I agree. Sounds like trapped air.
