Serpentine belt

[Guest]

What is the size of my serpentine belt in my 2005 Yukon Denali

there are two possibilities depending on your alternator output. there is a 105A and a 145A alternator option. one uses a little bit longer belt. If you can read the numbers on your old belt that would make it easier to match up. Or if you can find the information on your alternator.
