As I posted before I thought my belts were squeeking and it sounded like crap.dressed the belt(noticed the crank pulley belt jumped one track so I fixed that, I sprayed the guide wheels and the tensoner which was tight as he!! when I move the belt in the right spot,but I STILL have the squeek.what is the pump on the bottom right of motor?? sounds like its coming from down there. today I turned on truck and never heard it all day.Yesterday I couldn't drown it out with the radio all the way up.I DON'T KNOW WHAT IT COULD BE..........Any suggestions......I'm totally stumped on this one.

 

Maybe you got a vette or SS Camaro stuck up in your intake or something. They squeel like little bitches when ya suck 'em up! LOL!

Could possibly be your power steering pump?

 

Now I haven't heard it in 2 days so I don't know what the heck!!!
