CSF 3553 Radiator - Center

CSF 3553 Aluminum Radiator for Porsche Center Applications

The CSF 3553 is a 2-row all-aluminum radiator built for center-mounted cooling applications in select Porsche models. With aluminum core and tanks, a cross-flow design, and quick-connect inlet and outlet pipes, it is engineered for direct replacement use where consistent coolant flow and efficient heat transfer matter.

Key Features

• 2-row all-aluminum construction for the core and tanks
• Cross-flow radiator design
• Core thickness: 1 5/8 in.
• Core length: 24 in.
• Core width: 4 5/8 in.
• Inlet diameter: 1 3/8 in., right side
• Outlet diameter: 1 3/8 in., right side
• Quick-connect inlet and outlet pipe design
• No radiator cap included

Product Details

CSF manufactures radiators to high-performance standards and validates cooling performance through laboratory wind tunnel testing. The CSF 3553 reflects that engineering approach with an all-aluminum core and tank construction designed for durability and thermal efficiency. This radiator is a direct-fit cooling component for Porsche Boxster, Porsche 911, and Porsche Cayman center applications, and it cross-references Global Parts Distributors LLC 13163 and Spectra Premium CU13163 for the same application. The CSF 3553 is a practical choice when replacing a worn or leaking radiator in 2005-2012 Porsche Boxster, 2005-2011 Porsche 911, or 2006-2011 Porsche Cayman center cooling setups.

Common Problems This Radiator Can Address

• Coolant leaks from a damaged or corroded radiator
• Restricted heat dissipation from an aging core
• Overheating caused by reduced cooling efficiency
• Cracked or deteriorated plastic-tank style replacement concerns
• Fitment issues when replacing the original center radiator assembly

Installation Notes and Tips

Verify the inlet and outlet orientation before installation, since this unit uses right-side inlet and outlet connections. Confirm center-position fitment and compare core dimensions, hose connection style, and mounting points against the original radiator before removal. Because the radiator cap is not included, reuse or replace the cap separately if your application requires one.

Quality Assurance

CSF radiators are produced in ISO/TSO-certified factories and built for global OE and performance applications. The brand has supplied radiators worldwide for decades and uses engineering validation methods to support cooling performance consistency.
