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.

Nice Radiator, Perfect Fit
An exact fit for my 2005 Escalade ESV. Really nice build quality, had everything to hook the factory trans and oil cooler lines including the clips. Simple job when the part is an exact replacement part from GM.

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.

So much for genuine GM replacement parts
It leaks. Does anyone know what the warranty is on this radiator? The design changes are not for the better. No petcock and the trans cooler and oil cooler fitting are different on how they mount through the tanks. During installation the first leak was at the top oil cooler fitting. It appears the conical washer on the fitting was the problem. The fitting bottoms out in the oil cooler bung and the washer is supposed to hold things tight. I was able to reshape the curve of the washer a bit and that leak seemed to stop. But then as I filled the system with more coolant another leak appeared near the top of the drivers side tank right below the top hose neck. I am past the Amazon return window at this point and I'm very disappointed to say the least. I can't rate zero stars for what at this point is a useless part.

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.
