2001 Denali oil and antifreeze leak

I got a 2001 Denali with the 6.0l. It seems to be leaking engine oil to the rear of the oil pan on both sides. It has residue where the oil cooler lines are at, by the drain plug, under the bell housing and around the starter. Also, I noticed there was some antifreeze on the right side axle towards the right front of the motor. I can't see any signs of the water pump or thermostat leaking. Does anybody know where either of these could be leaking from?

retorx the bolts on the pan, then clean up the area, this should give you a ideal on ware the oil leak is. just hand tight is all you need to do.

clean off the motor very well, dry it off by warming the motor. then start looking for the anti freeze leaks and oil leaks.
