#127720, "RE: Rough idle after complete 420a rebuild." In response to In response to 2
Thanks for the help guys. I did not bleed the cooling system, just filled it up and went. But I looked in my Hanes manual and it says to fire it up without the radiator cap on and let the thermostat open. Then let the engine cool and refill the coolant and squeeze the upper hose to remove bubbles. Is this the method you guys used?
