Product Details

CSF manufactures radiators to high-performance standards and validates cooling performance through laboratory wind-tunnel testing. The brand supplies a wide range of radiator applications across many vehicle platforms, and this CSF 3300 follows that OE-style approach for the Lexus SC430. It uses a single-row aluminum core with plastic tanks to match the factory-style layout while maintaining the dimensions and hose connections needed for proper cooling-system service.

Compatible with Lexus SC430 models, this radiator is listed for 2010 Lexus SC430 and 2002-2009 Lexus SC430 with OE style design notes. The CSF 3300 is a practical choice when replacing a worn or leaking radiator on a Lexus SC430 and when maintaining the original down-flow configuration is important.

This part cross-references APDI 8012575 and AP Exhaust 2575 for the same application.

Common Cooling Issues It Can Address

  • Coolant leaks from cracked or aged radiator tanks
  • Reduced cooling efficiency from a restricted or damaged core
  • Overheating caused by radiator deterioration
  • Fitment problems when replacing a factory-style Lexus SC430 radiator
  • Cooling-system service needs on a 2002-2010 Lexus SC430

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this radiator uses a 1 1/2 in. left inlet and 1 1/2 in. right outlet. The listing notes no cap is included, and the CSF cap number referenced for this application is 4513. For 2002-2009 Lexus SC430 applications, the fitment notes specify use of a Micro, 16 psi cap. Confirm hose routing, mounting points, and transmission or oil-cooler connections against the vehicle before final assembly.

Quality Assurance

CSF radiators are manufactured in ISO/TSO certified facilities and built to validated cooling-performance standards. Part number 3300 reflects CSF’s OE-style radiator construction for Lexus SC430 applications, with the brand’s long-running radiator manufacturing experience supporting product consistency.
