CSF 3210 Radiator

CSF 3210 Radiator Overview

The CSF 3210 is an OE-style radiator built with a plastic tank and aluminum core for vehicles that use a down-flow cooling layout. It features a 1-row core, a sensor port on the top tank, and a high-efficiency plate-type oil cooler to support stable coolant and transmission fluid temperature control.

Designed for applications such as Toyota and Lexus models that use this radiator configuration, CSF 3210 combines factory-style fitment with CSF’s long-running radiator manufacturing experience. If you are searching for a radiator replacement for Toyota Camry, Toyota Avalon, or Lexus ES applications, this part number is built to match the original layout closely.

Detailed Description

CSF 3210 is engineered as a direct-fit radiator replacement for vehicles that require a down-flow, left-side inlet and outlet layout with a plastic tank and aluminum core. The radiator core measures 23 1/4 inches long by 21 9/16 inches wide, with a 1 1/4-inch thickness and a single-row design for factory-style cooling performance. The integrated sensor port on the top tank supports applications that rely on that OE feature, while the built-in plate-type oil cooler adds another layer of thermal management.

CSF manufactures a wide range of radiator designs for major vehicle brands, and this part reflects that OE-style approach for Toyota Camry, Toyota Avalon, and Lexus ES fitments where the original radiator configuration matches these specifications. The CSF 3210 is a practical choice when replacing a leaking, clogged, or damaged radiator and restoring proper cooling system operation.

This part cross-references Spectra Premium 2001-0701 for the same application.

What This Radiator Helps Address

• Coolant leaks from cracked or aging plastic tanks
• Overheating caused by restricted or inefficient radiator flow
• Transmission fluid temperature issues in oil-cooler-equipped applications
• Cooling system failures after impact damage or corrosion
• Loss of factory-style fitment on Toyota and Lexus radiator replacements

Installation Notes and Tips

Verify the inlet and outlet orientation, sensor port location, and core dimensions before installation. This radiator uses a down-flow layout with left-side inlet and outlet connections, so matching the original configuration is important for proper fitment. Inspect hoses, clamps, and the cooling fan system during replacement, and confirm the correct cap specification if the vehicle requires one.

Quality Assurance

CSF radiators are manufactured to high-performance standards in ISO/TSO-certified facilities and are validated through laboratory wind-tunnel testing for cooling performance. CSF has supplied radiators worldwide for more than 50 years and has produced over 30 million units across its radiator lineup.
