car makes strange noises while parked.

when the car is in the garage, a few hours after being driven, it makes these strange "burping" noises every few minutes. erk. erk. erk.

I've listened, and I can't pinpoint where it's coming from, other than the front end. is it the coolant system losing pressure as it cools off, or something like that?

its the oil and coolant cooling off if im not mistaken

i figured it might be something like that, but it had me wondering.
