I have a winning noise that is coming from the engine. The noise comes from the engine, when you start the car the noise is there. And when the car gets warmed up the noise is not as loud, but when you apply gas the noise gets louder as you apply gas and when you let of the gas peddle the noise goes away. For example when I'm on the highway or driving the noise only comes when the car is accelerating and when I'm not stepping on the gas the noise goes away. I have replaced the power steering pump and the water pump. After that the winning noise is still there. I used a stethoscope to listen to where the noise is coming from, and the noise is coming from the water pump when I'm listening and applying gas. I have noticed that the manufacturing has changed the design on the water pump for the Buick Rendezvous 3.4L. I don't know if that has anything to do with it. Please help me find out what I am doing wrong? I think that maybe the new water pump is bad. Also another thing is after flushing my radiator and the new water pump in, I only put in maybe about almost a gallon of coolant in the car. I even bled out the air bubbles out of the coolant lines, and I have heat in the car.
Do you

Check coolant tank level for enough coolant it will automatically bleed air out to there especially after running it a bit. Check your alternator for the noise as well as the belt and tensioner. Recommended replacement for the belt and tensioner is 60k or one of the idler pulleys if you have one.

I have checked all the tensioners and all of them are good. I have put a new belt in about 4 months ago and it's still in good shape. As for the alternator there is no noise coming from there. The coolant level is rite where it's supposed to be. I can hear the noise coming from the water pump when I use the stethoscope to listen to it. While listing to the water pump I accelerated the car and I can clearly hear the noise from there when pushing giving it gas and letting the gas off. The sound, sounds like the power steering pump without power steering fluid in it. Could it be that I put the pump in the wrong way or not tighten the bolts for the water pump pulley too much or not enough?

Without hearing it I couldn't tell you and putting it on computer is not much help. One thing though any time you change a belt you should also replace the tensioner as well because they lose tension
