Review on 🚙 ACDelco Serpentine Belt 12576447 - Original Equipment by Aaron Webb

Decided to replace the serpentine main drive belt (ACDelco 12637204) and A/C belt (ACDelco 12576447) on a 2002 Tahoe LT 5.3L with 143,000 miles. The main tensioner was at the end of the marks showing belt tension. I have an aftermarket K&N Performance air filter so I didn't have to remove the stock air filter to access the drive belt from above. Under the engine, behind the radiator, is a large cover which, when removed, gives you easy access to the A/C belt and main spool belt. I was able to remove the old straps and install the new straps with little effort. There are cheaper serpentine belts out there, but I've decided to stick with the ACDelco OEM quality as it hasn't failed me in the past. I highly recommend these belts.
