This was a great purchase and other than being difficult to install, everything was perfect and for far less than having to pay at a NAPA auto store of Benson auto.

Line arrived in perfect shape with all genuine GM labels attached. Fit like a glove. Made replacement very easy. NOTE: This line is for auxiliary cooler to top of radiator on 2011 Silverado 1500. It does NOT run to the transmission.

You don't want to have to take your truck apart again anytime soon, I promise so do yourself a favor and do the other lines now too.
