Gm Original Equipment Series Radiator 8, 6.0
Part Great, Shipping not so great
OEM radiator for 2016 Silverado , perfect fit, worked great, glad I went with genuine GM part. Shipping not so great. Said I would get it in 2 days, paid over $60 for shipping. should have been expedited shipping for that price. Took 5 days, they should be honest on the true shipping time.
