I have a 2004 Gmc envoy with 4.2 liter engine. 156,000 miles. I have a noise on the front of the motor that is getting louder and more anoying. I have a noise that sounds like a whine or could be called a growl. I have replaced the both the idler and tensioner pullys. I just replaced the power steering pump because you could move the pully when the belt was off. You could make it woble in your hand. I have ran the engine with the belt off and all the noises are gone.
I am about ready to pull the fan cluch and shourd out and run to see if that removes the noise.
Here is my question. Has any one had noise come from the water pump? I have had pumps fail but they have always leaked.
Please give my your input.
I have spun the alternaor it seams fine. I can not tell about the air condtioner pump.
Please help.
