I was looking for a larger size cooler than the stock one description said 16x12. The one I received is only 5x13 that is the dimensions of the actual cooler with out the brackets. I have not mounted it yet not sure if I am going to .it is same size as the stock cooler.

I have to say I love Dorman's stuff! They produce, and reproduce, quality replacements for many expensive factory pieces. This cooler is a great example. The factory piece is extremely pricey and often hard to get. This Dorman replacement fit perfectly, looks indistinguishable from, and functions just like the factory piece at a much lower cost.

Fit a 2002 Duramax perfectly. The nuts were a different size so use the ones from your old cooler, no biggie.
