Detailed Description

CSF 3138 is an OE-style radiator engineered for the 2005-2010 Scion tC. It uses a single-row aluminum core with plastic tanks to match factory-style cooling system architecture, while the cross-flow layout supports efficient coolant movement through the core. The inlet and outlet are sized at 1 5/16 in., with left-side inlet and right-side outlet placement for the listed application.

This radiator is part of CSF’s 1 Row Plastic Tank Aluminum Core line, a product line focused on factory-style replacement cooling components. For shoppers searching for a Scion tC radiator, Scion tC cooling system replacement, or CSF 3138 radiator, this unit provides the specified dimensions and OE-style configuration needed for the listed vehicle range. This part cross-references Hayden 2776 for the same application.

Common Cooling Issues Addressed

  • Leaking radiator tanks or core seams
  • Restricted coolant flow from an aging radiator
  • Overheating caused by reduced heat transfer
  • Corrosion or wear in the original cooling assembly
  • Cooling system performance loss in a high-mileage Scion tC

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet placement, and oil cooler configuration against the original unit before installation. This radiator does not include a cap, and the listed application notes specify use of a Micro, 13 psi cap. Inspect hoses, clamps, and coolant condition during replacement to help ensure proper sealing and system operation.

Quality Assurance

CSF manufactures radiators in ISO/TSO-certified facilities and validates cooling performance through laboratory testing, including wind tunnel evaluation. With more than 50 years in the market and a broad catalog of radiator applications, CSF 3138 is built to meet high-performance manufacturing standards for the listed Scion tC fitment.
