CSF 3631 Radiator

OE-Style Cooling for Chrysler and Dodge Vans

CSF 3631 is a cross flow radiator built with a 1-row aluminum core and plastic tanks for OE-style fitment and cooling performance. It is engineered for 2005-2008 Chrysler Voyager, 2005-2007 Chrysler Town & Country, 2005-2007 Dodge Caravan, and 2005-2007 Dodge Grand Caravan applications.

The CSF 3631 radiator uses an aluminum core with plastic end tanks and steel crimps to reinforce the assembly. Its cross flow layout, 1 1/4-inch core thickness, and left/right 1 9/16-inch inlet and outlet sizing support direct replacement needs for Chrysler and Dodge minivan cooling systems.

Detailed Description

CSF 3631 is designed for drivers replacing a worn radiator in Chrysler Voyager, Town & Country, Dodge Caravan, or Dodge Grand Caravan models from the 2005-2008 and 2005-2007 model years listed above. The OE-style plastic tank and aluminum core construction follows the factory layout while the cross flow configuration helps maintain proper coolant routing through the cooling system. CSF manufactures radiators to high-performance standards and validates designs through laboratory wind tunnel testing, with production backed by ISO/TSO-certified factories and decades of radiator manufacturing experience. This part cross-references Spectra Premium CU2795 and Anchor 2795 for the same application.

Common Problems This Radiator Addresses

• Coolant leaks from cracked or aged radiator tanks
• Restricted cooling performance from a clogged or corroded core
• Overheating caused by a failing factory radiator
• Heat-related drivability issues in Chrysler and Dodge minivans
• Replacement needs after impact damage or seam failure

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this radiator uses a left inlet and right outlet layout. Confirm the vehicle’s existing radiator matches the OE-style cross flow design and the listed dimensions before installation. Transfer and inspect related cooling components, and refill the system with the correct coolant mixture after installation. This radiator is listed for 2005-2008 Chrysler Voyager, 2005-2007 Chrysler Town & Country, 2005-2007 Dodge Caravan, and 2005-2007 Dodge Grand Caravan.

Quality Assurance

CSF builds radiators in ISO/TSO-certified factories and validates cooling performance through laboratory testing. The brand supplies a wide range of radiator models for major vehicle applications worldwide, and the steel crimp construction on CSF 3631 is used to improve assembly strength over standard OE-style construction.
