Exact replacement O.E.M. fit
Great product exact replacement for my original radiator fit like a glove. Only dislike is the way it's packaged. The box was ripped on one end and some of the fins in the center were bent over completely flat but did not leak. Took a half hour to carefully bend them straight with a small screwdriver.

Exact replacement for 2013 Escalade ESV Platinum
Exact replacement for my 2013 Escalade ESV Platinum. Original one held up 12 years and 155,000 miles so I think this one will last long after I am done with this SUV

Oem fit and function
Radiator fit perfect (03 1500hd). No petcock but it's just as easy to pop off the bottom hose to drain the radiator if need be. Also, a petcock is one less place to leak. Radiator was double-boxed and packed securely. Price was way less (<$200) than local part stores for cheap aftermarket units.

Perfect swap on 2010 suburban 2500.
Fit perfectly. Pull the clips that secure the oil&trans cooler lines, pull out lines. No special fittings to buy or rigging to make it work. Simple swap out. Did come with a couple minor bent fins. Understandable when dealing with flimsy cooling fins on radiators.
