Thread: Percolating Pontiac w/ Video of sound

Okay, I have an obnoxious problem.

Inside the cabin, whenever I slowly accelerate from a stop, I hear a percolating sound in the dash. It sounds like my car is taking a hit from a bong (I can't think of a better way to describe it).

I had the radiator replaced, upper and lower radiator hoses replaced and the entire coolant system flushed. The bleeder valve was opened to let the air escape and I believe it was "Burped," as we ran it and topped off the reservoir with coolant.

I'm PRAYING it's not the heater core. It's just the most obnoxious sound and it used to be pretty infrequent - now it's at almost every acceleration. My heat and a/c work fine.

Can anyone help me figure out what this could be?

Thank you!

Here is the video I took of my car in park. Turn up your speakers to hear the bubbling sound.

I think I'll try that. I don't even know where to go to find a hill!

How long should I sit and idle for? Should I do anything else? Rev the engine? I'm gonna take a video of the sound later today and post it to update this thread.

Thanks!

You may just need to have it flushed on a machine Mine had air in the system when i did a at home flush

Flushed it at school with the machine and had much better results still had to bleed the air off but that only took 2 times

Buy one of these. RADKITPLUSA, Vacuum/Filler, Cooling System

gurgling noise? just put up with it, as long as you get heat you're okay.

i may have to get one of those nice little setup

They work great, when I remember we have one at work lol.

Here is the video of the sound I am hearing. As you can see/hear, it's now happening with every acceleration.

Turn up your speakers to hear it.

Can anyone tell me what's causing this? How do I get rid of it.

My heat and A/C work fine, but this sound is REALLY loud and obnoxious.
