I fill radiator up 3/4 and allow to run and get hot. Meanwhile, front end is jacked off ground 6-8" so the cooling system can burp air pockets, then I fill slowly so all pockets bleed out.
This is a joke right??
No
I never heard of jacking up the car to bleed the air. I checked with Google and it appears it can be helpful. Perhaps it's a bigger deal with newer cars. I always had a overflow tank so I filled from the overflow tank and it seemed to do the job.
Note last paragraph: Raising the cooling system's pressure also raises the coolant's boiling point, so the radiator cap (which also could be on the engine or on the separate reservoir) has a pressure valve to raise the pressure in the cooling system by about 15 psi. This increases the boiling point of the coolant by about 40 degrees F. So, the boiling point of a 50/50 mix of antifreeze and water in a properly functioning system is about 265 degrees F or higher.
