I am putting in a new radiator today. do I just fill it by the overfill tank or is there a trick?
I hear ya. I have the mac tools version I had to purchase whenfilling the system in my track car - made me realize I should have bought one years ago. The cooling system runs from the front to the back with many flaps along the way. There is no way to bleed the system without driving it and risking overheating or the vacuum method.no all wrong... the only way to fill these engines is with vacuum filler. it puts the cooling system in a vacuum, sucks all the hoses down... if you do it any other way, the air bubbles will never go away. These cause cavitation and blow egr and oil cooler.
