Detailed Description

OSC Radiators are engineered as OE-style replacement radiators for vehicles that need dependable heat transfer and stable operating temperatures. Part number 13271 uses a crossflow layout with a PA core and plastic end tanks, along with 1 3/8-inch inlet and outlet connections for a direct-fit replacement in the cooling system. This radiator is listed for 2011-2015 Chevrolet Volt and 2014-2016 Cadillac ELR main radiator applications, making it a practical choice when replacing a worn or leaking unit on these platforms. This part cross-references Spectra Premium CU13271 for the same application.

What This Radiator Helps Address

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by restricted coolant flow or reduced heat dissipation
• Temperature instability from a damaged or inefficient core
• Cooling-system wear on higher-mileage Chevrolet Volt and Cadillac ELR vehicles
• Fitment issues when replacing the original main radiator

Installation Notes and Tips

Verify inlet and outlet sizing, core dimensions, and vehicle application before installation. For 2011-2015 Chevrolet Volt and 2014-2016 Cadillac ELR models, confirm the main radiator configuration matches the original unit. Inspect hoses, clamps, and surrounding cooling-system components during replacement to help ensure proper sealing and airflow.

Quality Assurance

OSC radiators are built with premium-grade materials and production checks that test the cooling components before and after assembly. The design also incorporates engineering updates aimed at addressing original design weaknesses and improving durability in high-mileage vehicles.
