Product Details

CSF 3173 is a radiator built to match the original equipment layout used in the Chrysler Pacifica cooling system. The 1-row aluminum core and plastic tank construction follow an OE-style format, while the cross-flow layout and measured inlet and outlet sizing support proper coolant routing. CSF manufactures a wide range of radiator models and validates cooling performance through laboratory wind tunnel testing, with production backed by ISO/TSO-certified factories. This radiator is a direct replacement choice for 2004, 2005, and 2006 Chrysler Pacifica vehicles, and the CSF 3173 part number is commonly referenced in radiator replacement searches for this application.

CSF’s 1 Row Plastic Tank Aluminum Core product line focuses on OE-style radiator construction for vehicles that require a factory-type fit and cooling layout. For shoppers comparing Chrysler Pacifica radiator replacement options, CSF 3173 provides the same general tank-and-core architecture used in the original system.

Common Cooling Issues Addressed

• Leaking or cracked radiator tanks
• Restricted coolant flow from an aging core
• Overheating caused by reduced heat transfer
• Corrosion or wear in the original radiator assembly
• Fitment problems from non-OE replacement parts

Installation Notes

Verify inlet and outlet orientation before installation: this unit uses a left inlet and right outlet layout. Confirm core dimensions and mounting points against the original radiator before removal. Cap is not included, so reuse or replace the existing cap as needed based on the vehicle’s cooling system specification. For Chrysler Pacifica radiator replacement work, matching the OE-style configuration helps ensure proper routing and fit.
