OE Equivalent Radiator Design

Koyorad A2723 is an OE-equivalent radiator built for direct replacement service in compatible cooling systems. It is a fitment-based radiator for the Mitsubishi Galant and uses an aluminum core with plastic tanks for a practical factory-style construction.

  • Fits 2004-2008 Mitsubishi Galant, N/A.
  • Aluminum core with a single-row design for efficient heat transfer.
  • Internal transmission oil cooler included for integrated cooling support.
  • 1.375 inlet and outlet diameters for matched hose connections.
  • Plastic tank construction for OE-style fit and function.

Fitment and Application

This Koyorad radiator is listed for the Mitsubishi Galant across the 2004-2008 model years. The A2723 part number identifies the correct replacement when matching the radiator configuration, including the built-in transmission oil cooler and the specified core dimensions.

Koyorad focuses on replacement radiators engineered with the technical experience needed for consistent service results. The A2723 follows that approach with an aluminum core, one-row layout, and integrated transmission cooling passages to support proper heat management in the cooling system.

Common Issues It Can Address

  • Coolant leaks from a damaged radiator tank or core.
  • Overheating caused by reduced heat dissipation.
  • Transmission fluid temperature concerns when the cooler circuit is part of the radiator.
  • Fitment problems from an incorrect radiator configuration.

Installation Notes and Tips

Verify core dimensions, inlet and outlet sizes, and transmission cooler configuration before installation. Confirm that the replacement matches the existing radiator layout on the vehicle and inspect hoses, clamps, and coolant condition during service. The A2723 part number should be matched to the application before removal of the original unit.

Quality Assurance

Koyorad positions this radiator as an OE-equivalent replacement and applies its manufacturing experience to produce a consistent, application-specific part. A2723 is built for direct replacement use in the listed fitment.
