From cold(overnight ) start with cap on radiator , does the system go from no pressure (rad hose soft), to lots of pressure (rad hose hard to squeeze , possibly feel bubbles going through it) in a matter of two or three minutes or less? If so , then you've probably got a head gasket issue. Get it diagnosed for sure , to make sure you don't have other issues.

Thank you for your input. Actually, it solved itself. I filled the radiator and resorvoir, and left it for an hour. Came back and the res. was empty. I put more fluid in it and left it. I repeated this process until the res. remained full. I started the truck and the heater came on right away, the truck is doing fine now. Strange! Isn't it?

Sounds like it .patience will yield good results in many cases , and sometimes in this business the best way to 'fix' certain issues is to watch and observe as you've found. keep an eye on it for a few more drive cycles and remember my first response if you notice it repeating itself with the air issue.
