OE-Style Radiator for Colorado and Canyon

CSF Radiator 3800 is an OE-style replacement radiator built with a plastic tank and aluminum core for direct-fit cooling performance. It is engineered for the 2015-2021 Chevrolet Colorado and GMC Canyon, with an upgraded heavy-duty core design for 2022 models.

The CSF 1 Row Plastic Tank Aluminum Core line focuses on factory-style fitment with performance validation. For drivers searching for a radiator for 2015-2021 Chevrolet Colorado, a radiator for 2015-2021 GMC Canyon, or a heavy-duty radiator upgrade for 2022 Colorado and Canyon applications, CSF 3800 is built around the original equipment layout.

Detailed Description

CSF 3800 is designed for cooling-system service on the Chevrolet Colorado and GMC Canyon platform. The radiator uses a 1-row aluminum core with plastic tanks in a down-flow layout, matching the OE-style architecture for straightforward replacement and proper hose alignment. The 2022 Colorado and Canyon applications use an upgraded heavy-duty core that is 11% thicker than the OEM 14 mm design, while 2015-2021 models follow the OE-style fitment profile.

CSF manufactures radiators for a wide range of vehicle applications and validates cooling performance through laboratory wind-tunnel testing. Part number 3800 is built to support factory-style cooling system restoration on the Colorado and Canyon platform without changing the original radiator layout.

This part cross-references OSC 13501 for the same application.

What This Radiator Helps Address

  • Overheating caused by a worn or restricted radiator core
  • Coolant leaks from aging plastic tank and core assemblies
  • Reduced cooling efficiency from internal blockage or corrosion
  • Fitment issues when replacing an OE-style Colorado or Canyon radiator
  • Cooling-system service needs on 2015-2021 Chevrolet Colorado and GMC Canyon, plus 2022 heavy-duty applications

Installation Notes and Tips

Verify inlet and outlet orientation before installation: inlet is on the right and outlet is on the left. Confirm radiator dimensions and hose routing against the original unit before removal. Inspect related cooling components such as hoses, clamps, and the thermostat during radiator replacement to help ensure proper system operation.
