07 Equinox heating issue

[Latino77]

i recently purchased an 07 Equinox LS. I am having an issue with the vehicle having no heat. There seems to be a lot of air in the cooling system. How can i bleed it?

if it's a 6 cyl. there are bleeder(s) above the engine. Don't know about the 4 cyl.

do you happen to know the thread size? i need to replace the screw

Its not just a screw but an assembly. Any auto parts store should have them. And don't tighten it so hard as it is made of brass.
