ACDelco Gold 38103 (88909593) Drive Belt Tensioner Assembly with Pulley

Work just like OEM.

Seems well made, perfect fit for 97 GMC 7.4

Fit great on the engine 5.7 of a 2000 Tahoe z71 "OBS", the screeching sound that occurred when the truck started has stopped (Take the opportunity to change the Serpentine Drive Belt with Gates K060966 Micro-V)

Best price I could find. Took about 30 minutes to replace. I had a squeal when I first started the vehicle up each morning. So I sprayed WD-40 around the old pulley bearings and the squeal went away for about two weeks. Then I sprayed the pulley again to make sure it was the tensioner pulley. It was, so I replaced the tensioner assembly and it cured the squeal.

Good part

Fit perfect in my 1999 Chevy Tahoe OBS 4x4

Half the price of parts store...lots of tension in that spring...install is a breeze

Works great, eliminated the squeaky from the old one

Fit great and quite

Se adapto bien a mi Chevrolet astro 02 motor 4.3 Vortec

Heavy, solid and seemingly quality. Fixed my squeeling noise. My only critique was it came in a big box with no packaging so it was probably bouncing around in transit, but i doubt it sustained any damage.
