first i would take out the plug in the thermostat housing next to the temp sensor and temp switch... You don't have to take the temp switch out , you can just remove the plug on the third hole there... and burp the system there with the key off and engine cool.. with the front end raised a little , top it off there as JR suggested..Then bleed through the bleeder afterwards with the key on engine off, heater full heat.. Then i would check the return line after that....If i can't get one to bleed usually that plug in between the temp sensor does the trick if i remove if and fill the system there...
