Good To Know

Q: Does this radiator include the transmission cooler lines? A: Check the product listing details for integrated cooler fittings, as some applications require internal transmission cooling provisions.

Q: Is this an original Chevrolet radiator? A: This is an aftermarket aluminum radiator and is not an original Chevrolet part, so confirm part number CU2423 matches your truck before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
