My Max produces a weird burbling sound when the heater is on and the engine is at idle. Has this happened to anyone else?

Yea.....there is some air in the system. It should be bled out. I don't know how to do it but its just a quick adjustment....not a repair.

I think my car makes that sound too, only when the air conditioner is on.

Bleed your radiator
there are two bleeder screws on the engine water jacket you need to open and air should bubble out from it
That helps mine.
