It is a 3-4" 90 degree tube on the firewall on the center-passenger side. Pull it off and see if ti is clogged. Oh, we’re talking about the A/C drain, I was still thinking heater core. I found it but I can’t get it off. It doesn’t seem clogged, at least not the opening, but I’ll have to try to get it off to be sure. I was thinking maybe air trapped in the heater core? :dunno: Is there anywhere to bleed the cooling system on these cars? The coolant level was full at the neck, but it was still warm, so I should probably check that when it’s cool too. --- _[View the full topic](https://forums.speedlife.net/t/water-sound-in-grand-prix/202378)._
