How to burp the coolant?

Hey guys,

I just replaced my oil cooler last week, and haven't had heat since...

How do you burp the coolant system on a 6.0L?

just leave the cap off and let it run for a little will work. at work, we use a vacuum fill (part#radkitplusa). if you work on the cooling system often, its a good investment. you suck the cooling system down to about 25 in vacuum and then it sucks the coolant out of the jugs, eliminating air pockets.
