Alright GMT800 veterans, what am I looking for here...

Earlier in the week, I noticed a ~1" puddle of pinkish-red fluid on the floor where I park the Escalade. Today, I saw a second ~1" puddle of pinkish-red fluid immediately adjacent to the first one, which was still there. Did the ol' finger test and it looks like coolant.

So, I figured it was water pump time. I knew I'd open the hood, see the coolant reservoir empty and a weepy, soaked water pump.

Nope, everything from top is dead dry. Coolant level fine, no moisture on belts, everything looks dead dry from the top.

What should I be looking for when I get around to getting underneath this thing?

Not sure the cutoff year/engine options for this, but look on top of the intake manifold, toward the back. My '94 has a rigid steel line that snaps into a fitting like this:


When those go bad, it can be a pretty small leak like you described. It's pretty easy (but potentially messy) to replace. Make sure the clamp holding that line is present and properly mounted - I had to replace mine a second time because the line was leaning to one side and deformed the seal inside the fitting.
