CSF 3579 Radiator

CSF 3579 Radiator Overview

The CSF 3579 radiator is an OE-style replacement built with a 1-row aluminum core and plastic tanks for the 2012-2017 Buick Verano. It uses a cross-flow design with quick-connect oil cooler fittings and is engineered to match factory cooling system layout for direct-service replacement.

CSF manufactures radiators to high-performance standards and validates cooling performance through lab testing, including wind tunnel evaluation. The CSF 3579 is part of the brand’s extensive radiator line for late-model vehicles, including Buick Verano applications.

Detailed Description

Built for 2012-2017 Buick Verano models, the CSF 3579 radiator follows an OE-style layout with plastic tanks and an aluminum core to maintain factory-style fitment and cooling system routing. The cross-flow configuration and 1-row core support efficient heat transfer, while the integrated plate-type oil cooler adds a factory-matched solution for vehicles equipped with this setup. If you are replacing a worn or leaking radiator on a Buick Verano, CSF 3579 provides the correct dimensions and connection points for a direct replacement.

This part cross-references Spectra Premium CU13246 for the same application.

Common Cooling System Issues

• Coolant leaks from cracked or aged radiator tanks
• Overheating caused by restricted or inefficient heat exchange
• Transmission or oil cooler connection concerns at the radiator
• Corrosion or internal wear in the original radiator core
• Fitment problems from non-OE-style replacement parts

Installation Notes and Tips

Verify inlet and outlet orientation before installation: inlet is on the right and outlet is on the left. Confirm the vehicle’s cooling system uses the matching oil cooler connection style and compare core dimensions, hose sizes, and mounting points against the original radiator before removal. Flush the cooling system and inspect hoses, clamps, and related components during replacement.

Quality Assurance

CSF radiators are manufactured in ISO/TSO-certified facilities and are tested for cooling performance validation. The brand has supplied radiators worldwide for decades and offers a broad catalog of OE-style applications, including the CSF 3579 for Buick Verano fitment.
