Built Around Factory Specifications

Part number 13333 is engineered as a direct-fit radiator replacement for Hyundai Elantra, Hyundai Elantra GT, Hyundai Elantra Coupe, Kia Forte, Kia Forte5, Kia Forte Koup, and Kia Soul applications listed above. OSC-style construction focuses on factory-style mounting, correct header sizing, and cooling performance that matches the original layout. This part cross-references Spectra Premium CU13333 for the same application.

Common Problems This Radiator Addresses

• Coolant leaks from aging tanks, seams, or core connections
• Overheating caused by restricted or weakened radiator flow
• Transmission temperature concerns when the cooler circuit is worn
• Reduced cooling efficiency in higher-mileage vehicles
• Fitment issues from non-OE-style replacement radiators

Installation Notes

Verify inlet and outlet hose sizes, cooler line routing, and mounting points before installation. The radiator is individually pressure tested and all necessary fittings or hardware are included in each unit. For best results, flush the cooling system, inspect hoses and clamps, and confirm the transmission cooler connections are clean before assembly.

Quality Assurance

OSC tests the radiator core before assembly and retests the completed unit during production, including transmission and engine oil cooler checks prior to installation into the tank. The design also incorporates engineering updates such as improved fin density and enhanced cooling capacity to address common failure points in higher-mileage vehicles. Part number 13333 is built to OE-style standards for fit and cooling performance.
