Coolant in vacuum hoses/intake?

[traildog]

While changing the water pump and thermostat, and moving some things out of the way, I found coolant in the 3-to-1 vacuum manifold that plugs right into the intake a few inches downstream of the throttle body.

It seems bad but my understanding of these engines isn't enough to know where it might be coming from, and Google is inconclusive.

Any thoughts? Thanks in advance

Never mind, what I thought was a 3 way vacuum connection is actually 2 coolant hoses and one vacuum line
