perfect fit

The correct size belt, perfect fit for my 2001 Chevy Tahoe. Some other parts stores will sell you belts that are close, but when installed, the belt tensioner gauge shows in the worn-belt area. Thank you, A1 Auto.
Excellent!

Everything was excellent all the way from the ordering to the online videos of the installation. This guy who never works on cars anymore was able to do all of it with ease! Great all the way around!
