Product Details

CSF’s 1 Row Plastic Tank Aluminum Core line focuses on OE-style radiator construction for direct replacement needs. Part number 3577 uses an aluminum core paired with plastic tanks, a layout commonly specified for factory cooling systems where packaging, hose routing, and heat transfer characteristics must align with the original design. The radiator also includes a high-efficiency plate-type oil cooler and quick-connect oil cooler fittings, making it a practical choice for vehicles equipped with integrated transmission cooling.

This CSF 3577 radiator cross-references APDI 8013146 and Spectra Premium CU13146 for the same application. It is a direct-fit cooling replacement for 2012-2020 Chevrolet Impala, 2011-2017 Buick Regal, 2010-2016 Buick LaCrosse, 2014-2016 Chevrolet Impala Limited, 2013-2014 Chevrolet Malibu, and 2010 Buick Allure.

What It Helps Address

  • Overheating caused by a restricted or aging radiator core
  • Coolant leaks from cracked or deteriorated plastic tanks
  • Reduced cooling efficiency from internal corrosion or blockage
  • Transmission temperature concerns on vehicles with an integrated oil cooler
  • Fitment issues when replacing an OE-style GM radiator

Installation Notes

Verify inlet and outlet orientation before installation: inlet is 1 3/8 in. on the right and outlet is 1 3/8 in. on the left. Confirm vehicle-specific fitment for your Chevrolet Impala, Buick Regal, Buick LaCrosse, Chevrolet Impala Limited, Chevrolet Malibu, or Buick Allure before ordering. This radiator is designed around OE-style dimensions and quick-connect oil cooler fittings, so matching the original configuration is important for proper installation.
