boiling noise

[L36Camaro]

I drove my car last night for only about 20 miles and when I got home I heard a bubbling sound so I opened the hood and it was coming from the radiator and the radiator hose. Could this mean there is air in the system or low coolant?
By the way, I saw NO coolant leaking around the hose or under the car.

.. its just the coolant running through the system after the car is turned off, its like that for everyone

It never made any bubbling noises before, just that night.

Its more likely to be making noise if there's an excess amount of air in the cooling system. Try bleeding your system.

My car makes that exact same noise...only when I've been running A/C though. I've noticed that if I dont have my A/C on and I shut the car off that noise is never there.

Thats a good point FirebirdHatesRice. It could be the sound of Freon equalizing in your A/C system.

Listen for the coolant to drain out of the engine into the radiator.. if you listen you can hear it flowing through the tubes.

Unless you have a 160 degree thermo. then the coolant is probably pretty hot..
