Need to identify a part

[yukonxl1500]

I finally determined that the coolant leak from my 00 Yukon Xl is coming from one of the metal hoses attached to enging body. It is located under the throttly body behind the alternator. It feeds off the ruber hose coming directly off the Throttle body. This metal hose branches off into three directions, with one being to/from the throttle body, the other to the left (passenger side) of engine and the last one looks like it goes deep inside.

Is there a place on the net were you can find a exploded view of parts like the dealerships have?

Thanks

If your 2000 is a GMT800 body style, do this mod and your problem may very well be solved.

Thanks, but it is not the rubber hose at the TB. Although the hose on the right joins a metao pipe/hose and it is that 3 way metal pipe/hose that I either need to replace or get a gasket for it.
