Welcome to the forum mrhlandscaping.
Sounds like the heater core may not have been bled when you finished the fittings.
Try checking the temp of the hoses by hand when truck is warm.
If big difference then you have no circulation through core.
Why did you change the fittings ?
What kind of 01 chev do you have ?

ok, not to be a jerk, but puncuation goes a long way. probably have an air pocket, all though I've never had a problem before with those trucks. check the level while its running, give it a few good revs to speed up the water pump and move some coolant. if that doesn't work you might have a kink in the hose or some sort of blockage..
