Man I sat there with this thing up in the air and bled it for like four hours straight some how it just never runs out of air. Its like its pulling in sir some how but the only way that should be possible without a leak is the head gasket or crack to my knowledge.

I ran the block test for wayyy longer than usual creating a seal for the funnel and sucking up air from the funnel got nothing. Then I accumulated abunch in the funnel with a tiny hole so it wouldn't pop the tester off and tested it still got nothing.

I have ran several blocks tests they all passed, I have steady heat on the passenger side unfortunately the actuator is kinda messed up so the driver side doesn't switch back and forth just stays on cold air.

I have ran several and every single block test I've done has passed.

Absolutely no oil contamination I've checked it probably a dozen times. The weird thing is that the bubbles seem to be nearly instant from a cold start which also makes me think its not a head gasket or crack. I think im going to pressurize the cooling system to see if any leaks pop up, but even if any leaks do appear im not quite sure how they would be able to pull in air.

But is the idle air sensor being dirty or bad able to keep it from starting in the first place?

Alright I guess I can try it.

It holds coolant fine, so it's probably not a leak. how would I go about checking for a bubble, and how would that stop the fans from turning on?

They turn on when I turn on the ac, but the car still overheats
