Detailed Description

CSF 3306 is designed for drivers and repair shops looking for a radiator replacement that matches factory-style fitment and cooling layout. This radiator serves the 2005-2010 Chevrolet Cobalt, 2007-2009 Pontiac G5, and 2003-2007 Saturn Ion, with a cross-flow configuration and a single-row aluminum core for efficient heat transfer. The plastic tank design follows OE-style construction, while the integrated plate-type oil cooler adds application-specific cooling support.

CSF’s radiator manufacturing is backed by ISO/TSO-certified factories and long-term global production experience. The brand states that its radiators are engineered and tested for cooling performance validation, and this CSF 3306 unit reflects that approach with a direct-fit layout for GM3010222, GM3010473, GM3010489, 52407483, and related applications.

What This Radiator Helps Address

  • Overheating caused by a leaking or clogged radiator
  • Coolant loss from cracked plastic tanks or aged seams
  • Reduced heat rejection from a restricted core
  • Transmission or fluid temperature concerns on equipped applications
  • Fitment issues from an incorrect replacement radiator

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this unit uses a right-side inlet and center outlet. Confirm hose routing, mounting points, and oil cooler line style against the original radiator before removal. The multifit oil cooler design uses adaptors for push-on oil cooler lines and quick-connect oil cooler fittings, so matching the vehicle’s original connection style is important for a proper install.

Compatible With 2005-2010 Chevrolet Cobalt, 2007-2009 Pontiac G5, and 2003-2007 Saturn Ion. This part cross-references Spectra Premium CU2608 and APDI 8012608 for the same application.
