Collapsed upper radiator hose

Like that idea. I think @Ricko1966 had recommended putting an aspirin or Tylenol tablet in the thermostat to prop it open for complete circulation before it dissolves and goes away. I haven’t tried it but sounds like a neat trick

Had Tylenol in the toolbox will those work? lol Anyway use whatever method is easiest to vent the air. There will almost always be a little residual, usually need to add coolant after first heat cycle or 2.

Might not be the best practice nut I allot of times drill a small hole in my thermostat to bypass a little and I've had no issues doing it this way for many years.

Side story: In HS a friend removed and drilled his thermostat 3 times to adjust his engine temp to perfection. I'm not saying he drilled 3 holes. He drilled one really small hole increasing it till the gauge showed perfect. Was also the same kid who cleaned his engine with Qtips and rubbing alcohol lol. We called him Mr. Clean
