Product Details
CSF 3129 is a radiator built to OE-style specifications for the 2003 Mitsubishi Outlander. The design uses a plastic tank and aluminum core layout, with a single-row core and down-flow construction to match the original cooling system architecture. CSF manufactures a wide range of radiator models and validates cooling performance through lab testing, including wind tunnel evaluation, to support consistent thermal management.
This part cross-references DENSO Auto Parts 221-3301 for the same application. The CSF 3129 also aligns with common replacement references such as Anchor 2617 and Spectra Premium CU2617.
Common Cooling System Issues
- Cracked or leaking radiator tanks
- Corrosion or clogging inside the core
- Overheating caused by reduced coolant flow
- Damaged inlet or outlet connections
- Cooling performance loss from an aging factory radiator
Installation Notes and Tips
Verify inlet and outlet placement before installation, since this radiator uses a center inlet and left-side outlet. Confirm the OE-style fitment for the 2003 Mitsubishi Outlander and inspect hoses, clamps, and coolant condition during replacement. The radiator cap is not included; CSF cap number 4503 is listed for reference.
