ACDelco GM Original Equipment 12637204 V-Ribbed Serpentine Belt

As advertised, correct length, super quiet when running, couldn't ask for a better product. Exactly what they said it was, OEM GM belt.

Fits perfectly

This serpentine belt replaced the one that came stock on my 2004 Chevy Suburban, and it was a direct fit / match. It was identical down to the printed numbers on the belt, and installed without issues. The stock one had 90K miles on it, and although I could have got a little more life out of it, it was time for replacement. Be sure to check the AC belt while replacing this - while my serpentine belt had some life left in it, the AC belt of the same age / miles had a lot of cracking and was definitely ready to be replaced. Thanks for reading.

Fit great. Good OEM quality belt.

Perfect fit would purchase again. Arrived on time.

Seems like the original one, I Just have the chance to install it today.

Product came as described. It replaced the original belt that came with the vehicle (10 years @ 120K mi). Installation was simple and since I have a K&N air intake setup on my vehicle, I had a enough space to see and work, I didn't need to remove any other parts to remove and replace the belts. Important to note that this is the larger serpentine belt, I had to buy a separate, smaller belt, for my 2006 Yukon Xl Denali that run the AC compressor ACDelco 4K378 Professional V-Ribbed Serpentine Belt . Both belts are quiet, no noise. I will be replacing the pulleys in the near future as well.

Decided to change the main serpentine drive belt (ACDelco 12637204) and A/C belt (ACDelco 12576447) on a 2002 Tahoe LT, 5.3L with 143000 miles. The main tensioner was at the end of the indexing marks indicating the belt was stretched. I have an aftermarket K&N Performance air cleaner so I did not have to remove the stock air cleaner to access the drive belt from above. There is a large cover underneath the engine behind the radiator, that when removed gives you clear access to the A/C belt and Main Serpentine belt. I was able to remove the old belts and install the new belts without any great difficulty. There are cheaper Serpentine Belts but I decided to stick with OEM ACDelco quality since it has not let me down in the past. Highly recommend these belts.

Tengo una Chevrolet Silverado 2003 1500 (2500 en Mexico) Cuando he necesitado remplazar alguna pieza solo ha sido con partes originales

Was used on a 2008 GMC savana 2500

Appears to be same as original. Shipping was slow even with the 2 day shipping

Same as the original for a fraction of the cost
