OK - Will try to answer all...How about I by pass the heater core all together ? - also I'll check & see where the temp sensor is...In other words the sensor is getting a false reading??? - Not sure about the bleed hole?
Ever wonder why all of these quirks never happened when these trucks were new? I remember back in the day I worked for an Olds/ Cad dealer & we had a 68 C-10 service truck, Nothing ever went wrong with it...& trust me it didn't get much love... Thanks for your input....
