Product Q&A

How is the core measured?  If I measure my current radiator (2013 GMC Sierra 2500 HD WT 6.0) it’s 40 inches from side to side (from outside edge of plastic side).  Will this one fit?David H.Feb 21, 2022
Best Answer:Hi David, I'm pleased to assist you. The core is the part of the radiator between the tanks. This radiator fits the 2013 GMC Sierra 2500 HD WT 8 Cyl 6.0L. The measurement of 40 inches side to side sounds about right. Click on the link below to order at 58% off the regular price today while supplies last. I hope this is helpful.
