Product Details
OSC part number 2565 is engineered as a direct replacement radiator for the Cadillac CTS 2003-2004 application. The radiator uses premium aluminum tubes and fins with plastic tanks, and the tubes are cadmium plated inside and out to help resist premature failure. The unit is built to factory-style fitment and includes the transmission oil cooler where originally equipped. This radiator cross-references Spectra Premium CU2565 for the same application.
Common Cooling System Issues
- Coolant leaks from a cracked tank, seam, or gasket area
- Overheating caused by restricted coolant flow or reduced heat transfer
- Transmission temperature concerns related to a failing cooler circuit
- Fitment problems after replacing a damaged original radiator
- Cooling performance loss on higher-mileage Cadillac CTS vehicles
Installation Notes
Verify inlet and outlet sizing, header dimensions, and cooler line spacing before installation. Transfer any required fittings or hardware from the original setup only if needed for your application. Confirm that the radiator matches the original downflow configuration and transmission cooler layout on your Cadillac CTS before final assembly.
Quality Assurance
Each OSC radiator is pressure tested during production, with cooler circuits checked before tank installation and the completed assembly tested again. 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 2565 is built to meet original-equipment-style cooling requirements for the listed Cadillac CTS fitment.
