Detailed Description

OSC part number 1776 is a replacement radiator designed for 1997-1999 Acura CL and 1995-1997 Honda Accord applications. It uses a premium aluminum core with plastic tanks and a concentric transmission oil cooler, matching the original cooling layout where equipped. The radiator is built for direct installation and is designed to maintain OE performance characteristics while addressing durability concerns found in higher-mileage vehicles.

For Acura CL and Honda Accord owners searching for a radiator replacement with OE-style dimensions and cooling layout, this unit provides the correct downflow configuration, header sizing, and cooler integration. OSC also uses engineering updates such as increased fin density and thicker core construction to improve heat rejection and service life.

This part cross-references Spectra Premium CU1776 for the same application.

Common Problems This Radiator Can Address

  • Coolant leaks from a cracked or aging radiator tank
  • Overheating caused by reduced heat transfer efficiency
  • Transmission fluid temperature issues related to a failing cooler circuit
  • Corrosion or internal wear in the original radiator core
  • Poor fitment or sealing from a previous replacement unit

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet sizes, and cooler routing before installation. This radiator is a downflow design and does not include a cap. Confirm that the vehicle uses the listed 1-row equivalent configuration and that the transmission oil cooler connections match the original setup on your Acura CL or Honda Accord.

For best results, inspect hoses, clamps, and coolant condition during replacement. Flush the cooling system if contamination or debris is present, and pressure test the system after installation to confirm sealing and proper operation.

Quality Assurance

OSC tests the radiator core before assembly, then tests the completed unit again after assembly. Transmission and engine oil cooler circuits are also tested prior to installation into the tank, helping verify sealing and cooling integrity before the part leaves production.
