the coolant hoses attach to the plate on the bottom of the throttle body..
not to the angled tube behind the throttle position sensor..
copy and paste this link...

large one goes to pcv... small one goes to the carbon canister..
sometimes.. gm dealers may print you out a diagram that shows the various emission and vacuum hoses..
be sure to save the links... i am probably going to delete them in a day or two...
