I bought this tool and works great getting the air out of the system. On my last Frontier there was Luke warm air at idle but hot driving and this fixed it. Hopefully it corrects your issue as well.
Lisle 24610 Spill-Free Funnel, was on amazon.

Hey Clint I bought that tool exactly how long did u bleed system and actually what did u do if u don't mind??

I put he truck facing uphill on small incline (my driveway) then installed the funnel and filled it halfway and watched the bubbles come and the coolant go into the radiator. You can also raise the idle and make it happen sooner. When done you install the plug and remove the funnel without spilling coolant. Make sure the heat is on while doing the procedure.

I had no heat at idle after a coolant flush. I followed this guys procedures and it fixed the issue.
