Radiator Overview

This OSC Premium radiator is built for direct-fit cooling performance and OE-style form and function. It is engineered for the Mazda 3 and uses premium-grade aluminum construction with plastic tanks for a practical replacement solution. Part number 13404 is a fitment-specific choice for drivers replacing a worn or leaking radiator.

Key Features

  • Premium-grade aluminum core construction with plastic tanks
  • Downflow design with a single-row core
  • Cadmium-plated tubes inside and out for added corrosion resistance
  • Pressure tested during production for leak verification
  • Cap included
  • OE-style fit and function for the Mazda 3 application

Detailed Description

OSC designed part number 13404 to match original equipment form and function while improving durability in a service replacement radiator. The core measures 28 5/8 inches wide, 14 3/4 inches high, and 5/8 inch thick, with 1 5/16-inch inlet and outlet diameters. The radiator uses a downflow layout and does not include engine oil or transmission oil cooling circuits. For Mazda 3 applications, this radiator is intended to restore stable coolant flow and maintain proper operating temperature under daily driving conditions. Part number 13404 is also cross-referenced with A13404 for the same application.

OSC radiators are individually tested during production, and the design includes fitted components assembled to factory specifications. The brand also uses a die-cut gasket to help maintain a leak-resistant seal. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

  • Coolant leaks from a damaged or aging radiator
  • Overheating caused by restricted heat transfer
  • Reduced cooling efficiency from worn internal components
  • Fitment issues when replacing the original radiator on a Mazda 3
  • Temperature instability in high-mileage cooling systems

Installation Notes and Quality

Fits 2014-2018 Mazda 3, N/A. Confirm the vehicle is Japan-built before ordering, since the fitment listing is limited to Japan-built applications. Part number 13404 is engineered for multi-fit use without changing the look or fit of the original cooling system. OSC states that each unit is pressure tested during production and built to OE cooler design standards where originally equipped.

Quality assurance includes production testing of the radiator assembly and cooler circuits before final release. OSC also emphasizes OE form and function, premium materials, and factory-spec assembly for consistent replacement quality.
