Product Details
OSC part 2412 is designed for Acura RSX radiator replacement applications where OE-style fit, cooling efficiency, and leak resistance matter. The radiator uses cadmium-plated tubes inside and out to help reduce premature failure, and the die-cut gasket is used to support a secure seal. This unit also includes the transmission oil cooler and follows the original cooler design where equipped, making it a practical choice for Acura RSX cooling system service.
This part cross-references Spectra Premium CU2412 and Koyorad A2412 for the same application.
Common Reasons for Replacement
- Coolant leaks from the radiator tank, core, or seams
- Transmission cooler seepage or reduced cooler performance
- Overheating caused by restricted or aging radiator passages
- Physical damage to the core, fins, or mounting areas
- Cooling system wear on higher-mileage Acura RSX vehicles
Installation Notes and Tips
Verify inlet and outlet sizes, cooler layout, and overall dimensions before installation. Inspect hoses, clamps, and surrounding cooling system components for wear, and flush the system if contamination is present. Part number 2412 is built for drop-in fitment, but final installation should follow factory service procedures for the 2002-2006 Acura RSX.
Quality Assurance
OSC tests the transmission and engine oil coolers before assembly, tests the radiator core before assembly, and tests the completed unit again after assembly. The design is engineered to meet original equipment cooler requirements where originally equipped and to support consistent fit and function.
