Is it possible to bleed the air bubbles out of the coolant by having a cold engine running with radiator cap off OR does the car need to run for 5 minutes (or however long it takes to get to normal operating temperature) with the cap off in order to properly bleed out the air?
I did this to my V6 + cleaned my intake mani + sea foam and I can tell a whole lot of difference with throttle response, idle, and in some other areas. definetly worth doing.
