Default mystery coolant leak

Lately I've been noticing a puddle of coolant on the ground under the seam between my front passenger side fender and my door.

I have a ProCharger kit and checked the hoses were 'T' connections were made and don't seem to see any coolant leaks.

Usually I notice a small puddle after the car has been sitting, but lately I've been moving it in and out of the garage and even just sitting for an hour or two it leaves a puddle.

Any suggestions on where to look?

I guess for '09 the waterpump had to be removed for the ProCharger bracket install, so perhaps it's just the gasket if it wasn't reinstalled quite right?

If the waterpump itself has failed (odd at 10,650 miles, but I've seen others post about early failures), what would indicate a failed pump vs. bad gasket?

The only thing I can think of that's remotely over there is the heater hose/transfer tubes, on the passenger side frame rail, leading to the heater core.

Add a trace dye to the coolant, drive and then inspect with a black light.

Heater core leak?

I assume it's safe for use w/ GM coolant

Yes, as long as it is compatible with Dex Cool.

Cool, I'll read the lables or ask the store if the clerk looks like he knows what he's talking about...
