04 2.7t little heat

Trying to bleed after coolant flush. Had it running at 2100rpm. Bottom heater hose hot, top luke warm. Some heat, but when idle back to normal no heat. Removed top hose from firewall while running at 2100 rpm and only very light stream of coolant coming out. When I remove cap from coolant resevoir get lots of bubbling at 2100rpm, non at idle. Heater core boockage, head gasket or both? 273K miles. It runs perfectly
thanks,
Dave

It's a bleeding issue.
I bleed it cold with compressed air. Works great.

Yes a bleeding issue. Try to find someone with a suction/vacuum pump. I think SnapOn's tool is called Vacula.

Fabricate an adapter from a expansion tank cap.

Not to much to say...Fill tank, open bleeders, use an air gun and a rag to force some air pressure into the tank to push all the air out the bleeders. When no more air comes out the bleeders, shut them.
