Truck Runs fine. And NO WHITE SMOKE OUT EXHAUST. Don't burn oil but coolant is turning to this.

 

How old is the coolant?

Ford uses "gold coolant" I'm most late model trucks

If it's rusty color you've probably way over due for a full flush
If it's oily you could have a leak in the trans cooler in the radiator or headgasket leaking

 

10thGen, welcome to the forum. You've posted your question in the section set up for comments to improve the forum, not to help you with problems in your truck.

Since you haven't told us what engine you have, I've moved your thread to the V8 section.

Patman has already given you good advice on what to look for, and perhaps others, now that your thread has been moved, will add their own thoughts.
