These engines had some issues with headgaskets leaking coolant externally. It is a small leak and usually only when hot, so there is no puddle because the coolant evaporates before it gets off of the block.
Get under the vehicle and, using a light, look at the rear face of both cylinder heads. If you see a greenish-white stain, that's the issue. This is a very labor-intensive job and should only be attempted by a qualified technician. I don't know your experience level, so I can't say whether you should try this yourself or not.
If you don't see any staining, a cooling system pressure test would be in order.
If you're located somewhere in central Pennsylvania, I could probably help you out.
Hope this is helpful!
