A few weeks ago I posted about a overheating issue. I've been on vacation but finally getting back to looking things over. The Denver shop that fixed the coolant meltdown left the vacuum hoses looking in a bit of disarray. After getting car back from the shop I also noticed almost stalling at idle. I need new spark plugs and decided to do the work today. All this to say, I noticed a few vacuum lines that seem have been left out. See pictures below. Any advice on what needs to be done to correct this if it's a problem. Any diagrams available?

Yeah, what @roversaid. What you circled is also a great way to remove the majority of air pockets in the block. Just remove the black clip and pop off the black coolant return hose from the gray pipe. That'll help with the overheating issue due to air pockets in the cooling system.
