Bubbling Noise Coming from my Engine Bay on 2021 Supra

[Acehub]

I just started noticing this bubbling noise coming from my supra and i’m not sure what it is. I just bleed my coolant lines and am still hearing the noise. If anyone knows what it might be it would help me out a lot. Thanks

Did you vacuum bleed and/or use the factory bleed procedures? If yes, the electric water pump often sounds like it's bubbling a bit. Most pumps do.

Which coolant lines did you bleed, theres two different systems with two different procedures.
