closed cooling system burp

[mkbruin]

So, what's your tricks? fill at the upper radiator hose? Fill at the upper heater hose? Fill from the temp guage sending unit (do you remove the unit altogether, or just the hose?)?

 

I hate these closed systems. But, factory radiator cracked and am gearing up to put in a replacement. I want to make the re-fill as painless as possible.

If the system was empty to start with I fill at the radiator hose, after removing the temp sender and parking it with the rear higher than the front. Then I top it off at the catch tank.
