CSF 2601 Radiator Overview

The CSF 2601 is an OE-style radiator built with a plastic tank and aluminum core for vehicles that need a direct-fit cooling replacement. It is engineered as a down-flow radiator with a 1-row core and a high-efficiency concentric oil cooler section, making it a practical choice for 1992-2000 Honda Civic and 1993-1997 Honda Civic del Sol applications.

CSF manufactures radiators to controlled production standards and validates cooling performance through lab testing and wind tunnel evaluation. The CSF 2601 follows that approach with a compact core design, center inlet, right-side outlet, and multifit construction to work with various fan shrouds.

  • OE-style plastic tank and aluminum core construction
  • Down-flow design with 1-row radiator core
  • Core thickness: 5/8 in.
  • Center inlet and right-side outlet, both 1 1/8 in.
  • Integrated 7 7/8 in. high-efficiency concentric oil cooler
  • Cap not included; CSF cap number 4513
  • Multifit design to accommodate various fan shrouds

Product Details

Built for Honda Civic radiator replacement needs, the CSF 2601 uses a 13 11/16 in. core width and 13 3/4 in. core length to match the OE-style layout while maintaining efficient heat transfer. The plastic tank and aluminum core combination balances durability and thermal performance for daily driving and routine cooling-system service. This radiator is also listed for Honda Civic del Sol fitment, giving buyers a direct replacement option for the same application family. Cross-reference part numbers include Spectra Premium CU1290 and APDI 8011290.

Common Cooling Issues It Can Address

  • Cracked or leaking radiator tanks
  • Restricted coolant flow from an aging core
  • Overheating caused by reduced heat dissipation
  • Oil cooler wear in radiator-equipped applications
  • Fitment problems from a damaged or incorrect OE-style unit

Installation Notes

Verify inlet and outlet orientation before installation: center inlet and right-side outlet. This radiator is specified for use with a micro, 16 psi cap, and the OE-style design should be matched to the vehicle’s fan shroud and hose routing before final assembly. For 1992-2000 Honda Civic and 1993-1997 Honda Civic del Sol applications, confirm all mounting points and cooling connections against the original radiator.

Quality Assurance

CSF states that its radiators are manufactured to high-performance standards and tested for cooling validation. The brand also notes ISO/TSO-certified factories and more than 50 years of radiator production experience across a broad catalog of vehicle applications.
