The radiator is built with a die-cut gasket for leak resistance and is assembled to factory specifications for fit and torque. This unit also includes a concentric transmission oil cooler and is designed to meet original cooler design requirements where equipped.

For buyers searching for an Acura Legend radiator replacement, a 1991 Acura Legend cooling system repair, or a 1995 Acura Legend radiator with transmission cooler, this part number 1278 provides the correct OE-style layout and dimensions. It is also cross-referenced to APDI 8011278 and Spectra Premium CU1278 for the same application.

What It Helps Address

  • Overheating caused by a leaking or restricted radiator
  • Transmission fluid temperature concerns tied to a failing cooler circuit
  • Coolant loss from cracked tanks, worn seals, or core damage
  • Reduced cooling efficiency in high-mileage Acura Legend vehicles
  • Fitment issues from non-OE-style replacement radiators

Installation Notes and Tips

Verify inlet and outlet sizes, core dimensions, and cooler layout before installation. This radiator is designed for direct replacement in 1991-1995 Acura Legend applications, and all factory-style fittings should be matched to the vehicle’s original configuration. Flush the cooling system, inspect hoses and clamps, and confirm proper coolant fill and bleed procedures after installation.

Quality Assurance

OSC tests complete radiators during production, including cooler testing before tank installation, core testing before assembly, and a final test after assembly. The design also incorporates engineering updates aimed at improving durability and cooling performance in higher-mileage vehicles. Part number 1278 is built to OES form and function standards for the Acura Legend platform.
