Hey was just wondering if anyone has encountered this kind of bubbling after getting the air out of the system and the heater core working again. Kinda looked like boiling coolant but also exhaust gasses?



I also ended up getting a block test and tried to get that to work through the rad but the rad kept overflowing too fast when heating up for me to get an accurate reading. I was maybe able to get 1 min of pumping at operating temp before it overflowed. Result was negative.

 

Not sure if that's normal, but it looks pretty foamy.

Like green beer on Saint Pat's day.

 

It does look pretty foamy, but you will get some activity in the funnel as the engine heats up and the fluid expands. Especially when you rev the engine, you're going to get some movement/action. Normally you won't get bubbles or foam once the system has been fully purged.

Did you use any kind of flush product in the coolant system before refilling?
Cheers!
