Flex-A-Lite Extruded Core Radiator and Electric Fan 1999-2012 Full Size 1/2-ton GM truck and SUV with 28-inch Radiator Core

Quick Overview

Direct-fit Flex-A-Lite® Extruded Core performance aluminum radiator and dual electric fan system for 1999 1/2- 20012 full-size 1/2-ton Chevrolet or GMC truck and SUV with 28-inch radiator core.


Flex-A-Lite® Extruded Core Technology is the future of performance aluminum radiators, replacing multi-core radiators with a new advanced design. Flex-A-Lite® Extruded Core Radiators provide significantly better cooling with a stronger, more durable and lighter design.

This direct-fit radiator is engineered to bolt into a 1999 1/2 - 2012 full-size 1/2-ton Chevrolet or GMC truck or SUV. No cutting or drilling is required for installation, and the radiator will mount using the factory location and equipment. Includes a fully-shrouded dual-fan system that moves 4,600 cfm of airflow and a Variable Speed Controller.

Note that there were 2 different sized radiators used in this series of trucks. This part number is for use in trucks that originally came with a radiator that measured 28-inches across the width of the core. If your radiator measured 34 inches, please use part number 316200.

Key features and benefits of the Flex-A-Lite® Extruded Tube Core Radiators include:

  • Increased contact area between the coolant and aluminum tubes for better heat rejection and cooling
  • A flat surface on which to braze the cooling fins, maximizing the contact between the tubes and fins for increased heat rejection and better cooling
  • The cooling fins have been designed with louver patterns cut into them to direct airflow, improving heat rejection and cooling
  • Wind-tunnel testing has shown that this Extruded Tube Core technology is significantly more efficient for cooling than standard tube radiators
  • The Flex-A-Lite® Extruded Tube Core Radiators are significantly stronger and have a 100-psi burst rating
  • The Flex-A-Lite® Extruded Tube Core Radiators include a corner subhead, reinforcing the cooling tube to header connection, an area prone to cracking and leaking in other brands of aluminum radiators
  • Covered by an exclusive Flex-A-Lite® transferable 2-year warranty

Note: Flex-A-Lite® radiators do not have built-in transmission coolers. This is done to provide optimum cooling for the engine, and we offer advanced-technology transmission coolers for optimum cooling of the transmission. Please see the transmission coolers available on our website.
