GM OEM radiator works great for past year
This worked great in my '06 2500 Silverado. OEM standard and great packaging.

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.

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.
