Hey guys, ever since I did my LT install I've noticed a boiling sound coming from the passenger side after I shut the car off. I'm pretty sure it did this before I even used the AC and now that I'm using AC I notice water dripping from the passenger header. Is the water just from the AC? What would cause the boiling sound from the header? I read one thread saying it could be the thermostat being stuck, but my temps are fine and it seems to come from the header and not the thermostat area. Thanks

It sounds like condensation from the ac. When it leeks see if its water or if it smells like coolant. Does it happen even if you dont use the ac?

Well the boiling sound seems to happen either way. I'm pretty sure the water is purely water and condensation but the boiling is the main thing I'm wondering about. The car seems to run fine so I don't know what it could be or if it's normal or anything.

If the ac is dripping on the header that would be the boiling sound you would hear

Well, I'm pretty sure that's not the boiling noise because it did this before I ran my AC at all. I probably just won't worry about it lol

The boiling sound could be the antifreeze in the radiator or overflow tank (It's on the pass. side... I've never had any of my cars boil from there). I know my Monte Carlo boils in the radiator after it's off. Not sure about the T/A... never listened to it. The water dripping from the AC is just distilled water, I wouldn't worry about that.
