I always wondered if on the stock radiator of the roadrunner you want it filled to the top or leave it a little low ( like an inch below the cap).


From the Service Manual page 7-5 under Installation: "(3) Fill cooling system to 1 1/4" below the filler neck seat with water and rust resistor or water and anti-freeze, as required. After warm-up, re-check coolent level.
