Tahoe: belt..weve replaced parts trying to fix it, it..squeal

Customer Question

I have an 01 Tahoe in which the belt is squealing something awful. It wasn't so bad in the beginning, but as we've replaced parts trying to fix it, it's only gotten worse. The squeal is coming from the front in the middle and possibly lower than higher. When we take the belt/s off, it goes away (so I'm quite sure it's the belt). Already replaced both belts (twice), the alternator, water pump, idler pulley, tensioner/s, clutch fan...and I think that's it. Also, the A/C does not seem to be the problem. I have heard a few other Tahoe's squealing down the road as well so I'm hoping you know what else may have gone bad and or should be checked. I'm am thinking something one of these pulleys is riding on is just a little off, making the belt ride a little off & causing the noise. PLEASE HELP!!!!

Hello, you may want to take a look at this bulletin from GM concerning belt noise and see if it helps you. Thanks

Document ID# XXXXX
2001 Chevrolet Tahoe - 4WD

Subject:Accessory Drive Belt Whine (Reposition Power Steering Pump Pulley) #01-02-32-007 - (08/20/2001)


Models:2001-02 Chevrolet and GMC C/K 1500 Series Utility Models (Tahoe, Suburban, Yukon, Yukon XL, Denali, Denali XL)
Built at Janesville Assembly Plant (Plant Code J) from December, 2000 through July, 2001


Some customers may comment on a whining-type noise that is audible in the vehicle's passenger compartment. This noise can typically be heard when the vehicle is idling and may vary in pitch as engine RPM is increased.


The power steering (PS) pump pulley may be positioned too far inboard on the PS pump.


Inspect the PS pump pulley for proper positioning on the PS pump shaft. If it is determined that the pulley is not even/flush with the end of the shaft (+/- 0.25 mm (0.010 in) following the applicable Service Manual procedure and using J 25034-C, reposition the PS pump pulley.
