Like Brent said,,,,,

you got to make SURE there is no air in the system. On my ERA I was SURE,,,,,,, and I was mistaken!!! There WAS air and I had to jack up the car on one side and bleed the top of the radiator which was LOWER than my fill tank. A "bubble" was trapped in the top of the radiator and all the flushing in the world didn't get that air out! NOT till I jacked it up and opened a pet cock valve at the top corner of the radiator!!!
