CSF 3145 Radiator

OE-Style Radiator for Toyota and Lexus

CSF Radiator 3145 is an OE-style replacement radiator built with a plastic tank and aluminum core for direct-fit cooling service. It is engineered for vehicles that need a down-flow design, a mini 16 psi cap, and factory-style hose and mounting dimensions.

Compatible With 2002-2008 Toyota Camry, Toyota Solara, Lexus ES300, and Lexus ES330 applications, this radiator supports everyday cooling system repair on the Toyota Camry and related Lexus models. CSF 3145 follows the brand’s 1 Row Plastic Tank Aluminum Core line for a factory-style fit and finish.

Product Details

CSF manufactures radiators to high-performance standards and validates cooling performance through wind-tunnel testing. The 1 Row Plastic Tank Aluminum Core line is built for OE-style replacement needs, using a plastic tank and aluminum core layout that matches the factory configuration on many Toyota and Lexus vehicles. CSF 3145 is designed for applications that call for a mini 16 psi cap and a down-flow radiator layout, making it a practical choice for restoring proper coolant flow and heat rejection in the cooling system.

This part cross-references DENSO Auto Parts (221-0503) and Spectra Premium (CU2434) for the same application.

What This Radiator Helps Address

• Overheating caused by a leaking or restricted radiator
• Coolant loss from cracked plastic tanks or aged seams
