I don't want to scare you, but....
my car used to gurgle when started until I replaced the head gaskets. That problem is gone now.
A couple of questions for you. What does your coolant overflow bottle look/smell like? It should be nice and white inside. If you've got any dark, gooey, burnt smelling substance on the inside of the bottle, you may have a more serious problem. Has the car EVER overheated?
