Thread: asking one last time before i do it...

when you guys say fill the radiator back up are you saying to put the coolant in the resovoir tank and leave the radiator cap open to let the air bubbles out?

well you have to flush between each step.......but when you refill it first fill up the radiator itself to the top....forget about the overflow for now except to rinse it out.
1)drain original coolant out, rinse, refill with water and get up to temp.
2)drain that out......rinse.......refill with water and cleaner and get up to temp and run that for 4-6 hrs or whatever the cleaner calls for
3) drain that out, rinse, refill with water and get up to temp.
4) drain, rinse and get up to temp, drain it and finally refill with the coolant and water mixture.
PLEASE NOTE: Have the heat on for atleast a couple minutes with each step as this will clean out all coolant and other stuff that is in the heater core and lines for it. you dont have to leave it on at all times, but atleast for five mins for so while it is up to temp.
