Gurgling Sound From Under the Hood

[the4starish]

Ive said this before, but recently Ive had the strangest luck with my car, heres the new problem:

Whenever I start my car, I hear a gurgling sound from under the hood. As soon as I start driving and give it some gas, I hear the flow of gurgling increase, when i take my foot off the gas, the noise drops. This goes on for a few minutes of driving then it fades/goes away. It sounds kinda like when you live in a two-story home and someone upstair flushes the toilet and you hear the water running though the pipes. I just added radiator fluid to the car recently and it started up after that.

Sounds like air in it..

Interesting...how do I fix that? Do I need to fix that?

Just try flushing you radiator. While flushing make sure your heater is on in the car and have the fan on high. Hope this helps!
