had a small puddle about the size of a quarter this morning on the floor, upon initial inspection, I cant see anything and the truck is not low on coolant, anyone have any ideas of where its from? thanks in advance.

what side was it on? front of the engine, rear of the engine? it's a crap shoot otherwise..

it seems to be slightly to the left of center of the motor

Water Pump weep hole most likely... look up under the truck and see if you can find any coolant residue on the front timing cover of the motor

If its the water pump, have fun and good luck cause its a b$%^h!! :mad:. I just got done changing mine this past weekend. I also managed to break a harmonic balancer bolt while doing it. Its a good 2-4hr job.

well hopefully the original poster has a warranty and can take it in if it needs replacing.
