Product Line Details

Detailed Description

CSF 3127 is a radiator for 2003-2006 Mitsubishi Lancer models, including Series 7, 8, and 9 notes listed in the fitment data. It uses a single-row aluminum core with plastic tanks and a down-flow configuration, making it a direct replacement for vehicles that call for this OE-style design. CSF states that its radiators are manufactured to high-performance standards, validated through wind-tunnel testing, and produced in ISO/TSO-certified facilities. This part cross-references Anchor 2676 and APDI 8012676 for the same application.

What This Radiator Helps Address

• Overheating caused by a leaking or restricted radiator
• Coolant loss from cracked plastic tanks or aged core joints
• Poor heat transfer from a worn factory radiator
• Fitment issues when replacing the original down-flow radiator
• Cooling system service needs on 2003-2006 Mitsubishi Lancer models

Installation Notes and Tips

Verify the inlet and outlet locations before installation: inlet is 1 3/8 in. center and outlet is 1 3/8 in. left. This radiator does not include a cap, and the listed CSF cap number is 4503. Confirm the vehicle uses the OE-style plastic tank and aluminum core layout before ordering. For best results, inspect hoses, clamps, and coolant condition during radiator replacement.
