2001 heat not getting hot
Getting air out of these can be a real problem, I have had good luck filling the radiator as full as possible then removing the bleeder and using a small funnel start adding coolant slowly through the bleeder hole, add until it won't take any more then put the bleeder screw back in. Note: do this slowly, too fast and you can trap a bubble.
Remember these are backwards cooling systems, so the hot coolant enters the bottom of the radiator and is forced up through the radiator, you may have to raise the front of the vehicle about 6 to 8 inches to help with the bleeding.
Ours done the same thing. It was our blend door under the dash . Fixed now and works great.
