Detailed Description

CSF 3243 is a replacement radiator designed for cooling systems that require an all-metal construction and a down-flow configuration. The copper-and-brass build supports heat dissipation and long-term service in demanding driving conditions. With 1 1/2 in. inlet and outlet connections, this radiator is built around OE-style dimensions and routing for select Toyota and Lexus fitments.

This part cross-references Spectra Premium 2001-0702 for the same application. If you are replacing a worn or leaking radiator on a Toyota or Lexus vehicle, CSF Part Number 3243 provides a direct-fit cooling solution with the correct tank layout, sensor port, and heater pipe provision noted in the technical description.

What This Radiator Helps Address

• Coolant leaks from a cracked or corroded radiator
• Overheating caused by restricted coolant flow
• Reduced cooling performance from an aging core
• Oil temperature management needs in radiator-equipped systems
• Fitment issues when replacing an OE-style down-flow radiator

Installation Notes and Tips

Verify core dimensions, inlet and outlet orientation, and the top-tank heater pipe and sensor port before installation. Confirm that the vehicle uses a down-flow radiator with 1 1/2 in. left inlet and 1 1/2 in. right outlet connections. Inspect hoses, clamps, and mounting points during replacement to help prevent repeat cooling-system issues. Fits select Toyota and Lexus applications that match the OE-style configuration for CSF 3243.

Quality Assurance

CSF states that its factories are ISO/TSO certified and that its radiators are engineered to high-performance standards. The brand also notes wind-tunnel testing for cooling validation and more than 50 years of radiator manufacturing experience across a large vehicle catalog. Part Number 3243 reflects that manufacturing approach with an all-metal construction built for cooling-system service.
