This is NOT a how to video, because I don’t know what I’m doing.

I’ve been having a hell of a time trying to get the air bubble out of that engine or heater core, ever since I changed the heater core.

I could hear bubbles rushing through the heater core occasionally, But since I’ve done this job I haven’t noticed it.

Hopefully I solved this problem and the cars occasional overheating.

The car only overheated when the temperatures were above 85° ambient temperature, and then when I got the coolant bubble to move the cars temperature normalized.
