It sounds like you have air in your cooling system, Check your coolant level and add if your low. Fill the radiator if your low on coolant and the over flow tank with GM Dex cool with 50/50 mix of water. open the radiator cap to the first click to allow the air to work it's way through out the system and out through the radiator cap and in to the over flow. Once the engine cools down, the coolant in the over flow tank will flow into the radiator, so keep an eye on the over flow tank and refill to the full mark as needed. If you have not flushed out the coolant system, you may want to. The GM Dex cool has a life expectancy of 5 years or 150.000 miles, and should be replaced. The capacity of your cooling system is 11.5 liters, good luck.

I have Chevy epica 2009 running 60 k km While accelerating a gurgle sound comes out from the beside a high engine noise over the speed of 80 and I sense low acceleration in general


That noise is associated with coolant. Check your level. Low? look for leaks. Some times it is just a water/coolant trail, because it is a small leak. It evaporates.

Clicking sound


There are obviously many different potential sources for this noise!

It would be helpful if we could know exactly where you hear it coming from, but, alas, I will give sometips.

If it happens during acceleration, then it could be from "pinging" from bad gasoline, you could change to a higher grade (87 to 91).

A rotating part such as a pulley, water pump, etc could be making these noises from under the hood. If you hear it, try to open the hood and listen to isolate the sound!

It could be coming from the transmission. Your torque converter may be slightly tapping the housing (not likely, but have seen on another vehicle that had a tranny job done recently).

Again, if you can further narrow down the location, it would be helpful.

Are any check engine lights or ABS lights on, or any other abnormal lights on in the dash?

2005'Towncar. 40k miles. Started making an odd sound on acceleration; hard to describe but sounds like it is coming from passenger dash side. Maybe an air noise?? No sound on very soft acceleration


Turn off heater/air conditioner and accelerate briskly. If noise does not occur problem is probably a regulator in the heater/air conditioning system located under the dash.

Why would the sound of water flowing through a tube happen when we start to accelorate?


The sloshing noise may be caused from air in the cooling system.

If there's air in the system, it ends up in the heater core because it's the highest point in the cooling system. When you accelerate, the water pump spins faster pushing coolant into the heater core forcing the air out causing the sloshing noise.

To remove any air from the cooling system, get the engine up to operating temperature. With the engine idling loosen the upper radiator hose clamp. take a small flat bladed screwdriver and slip it between the upper radiator hose and the radiator hose neck. Allow the engine to idle until all that comes out from the radiator hose is coolant. Retighten the hose clamp.

What noise are you referring to. Is it engine noise, or wind noise, or road noise? Is the noise there at cruising speed or just when you are accelerating? Please clarify.

My 2003 Jeep Liberty heater is blowing cold air when idling. Warms up when you hit the accelerator. I also hear a water rolling sound upon take off after idling. Water pump? Heater Core?


Water level perhaps. When you hit the accelerator the water volume increases. Check your water level and make sure that your thermostat is opening and closing properly. Water level I'm thinking

2005 Kia Sorento gurgling noise behind dash


Check the water coolant level because some of the hot water goes into the heater radiator behind the dash. Seems you have air in the system.

Liquid noises coming from the dash board


heated water goes to your heater core under your dash..though you shouldnt be hearing it usually..be sure water level is up at radiator overflow reservoir and pay attention in cabin of any sweet smell of coolant indicating a failing /leaking heater core....look for damp carpet on passenger front area if suspicious
