hey guys, i tried to search around but i dont see any similar problem with this. hence this new thread.

i have a 04 auto 73k miles gt package. i can hear sloshing sound whenever i rev, even when the car is on the run. any idea?

 

It's just the coolant moving through. It's normal. Also, check the coolant level just to be safe. My coolant light would turn on when the car was first started, and then go away in a couple of minutes. I would also hear that noise. When I topped off with coolant, I don't hear the noise as much.

 

When your car is cool, open the radiator fill tank, pressurized air will come out. Ensure that the coolant level is sufficient. Close the tank. Turn on the car and turn the heat on full hot with A/C on and the fan on max, let it run for a while (15 mins). Noise should go away.

 

sad to tell you, my heater doesnt work although the thermo reads fine (holding radio button and scan up button). anyhow, i'll try this way later

but i just serviced my car 2 weeks ago. (change engine oil, flush coolant, etc)

 

I have that same thing happen to me sometimes !!! I never really thought of it to be a problem cause my mechanic said my cars in tip top shape . Guess its normal

thank you so much guys! appreciate your time very much

 

I have the exact same problem!!

 

Is this when the car is moving? I never noticed this before I took out my interior and all the sound dampening material but I can hear the gas sloshing around in the tank sometimes... nothing out of the ordinary though.
