After finishing the valve cover gasket, put everything back together and added coolant to both reservoirs. I noticed some noise after 10 minutes of running, turned out the intercooler coolant reservoir was empty so i added water and the noise went away, let it run again and there is noise from underneath it which I believe is the turbocharger auxiliary pump which pumps coolant to the intercoolers. Is it possible it went bad because it was empty for a few minutes? Below is a video.
Oh, and i did do the bleeding procedure only after i heard the noise as i forgot to do so, and i have heat coming out if the vents now.

I removed it and ordered one, it's a common issue on these cars, hopefully that is the issue.

Hi,

It sounds like you found the issue. Also, it isn't uncommon for these to fail. When you get it back together, let me know if the issue is resolved.

Take care,

Joe
