Went to change oil & filter, got underneath-saw orange-ish fluid. Pics from top & bottom:

The hose does not feel wet or any drips where it attaches. Is this likely a water pump? Thanks guys.

 

Yep, water pump has a weep hole that will start to leak as the seal wears.
I recommend you replace the coolant, radiator hoses, and thermostat while you've got it apart.

 

Thank You for the response.

I have a lifetime warranty on the truck but no appointments available until Oct. 13th. Am I OK to drive it until then? I only put about 25-30 miles per day on to go to work & back. By the way, where is the weep hole located?

 

You'd be ok to drive the truck. Be sure to keep the overflow tank full. You may start to notice puddles under the truck.
The weephole is usually on the top side of pump, closer to the pulley than the block.
Coolant really lights up under black/UV light. A cheap flashlight will do.

 

Thanks again!

Much appreciate the knowledge and input.
