Hello,

I have 08 G35s. It is been hot in Vegas so AC is on most of the time. The other day I started to hear for what I can describe a fan gurgling noise audible when AC is on with brake depressed. If I cut the AC it goes away. AC is nice and cold though.

Any suggestions as to where to start looking at??

Thanks

 

Is it air bubble in coolant system? Sometimes if air gets in, sounds like water running down a pipe if theres a bubble of air in cooling system.
