Product Details

CSF’s 1 Row Plastic Tank Aluminum Core line focuses on OE-style replacement radiators built to match factory fitment and cooling layout. Part Number 3130 follows that approach for the Mitsubishi Outlander radiator replacement market, combining a lightweight aluminum core with molded plastic tanks for a factory-type configuration. CSF states its radiators are engineered to high performance standards and validated through wind tunnel testing, with manufacturing experience across a broad range of vehicle applications.

This radiator is a direct-fit option for 2004-2006 Mitsubishi Outlander cooling system service when the original unit is cracked, clogged, or showing signs of age. It also cross-references Anchor 2617 and DENSO Auto Parts 221-3301 for the same application.

Common Problems This Radiator Addresses

• Coolant leaks from aging plastic tanks or seams
• Restricted coolant flow from internal corrosion or buildup
• Overheating caused by reduced heat transfer efficiency
• Damaged radiator core from road debris or vibration wear
• Cooling system service needs on a 2004-2006 Mitsubishi Outlander

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this unit uses a center inlet and left outlet layout. Confirm the vehicle’s radiator cap requirement separately, since a cap is not included. Inspect hoses, clamps, and surrounding cooling components during replacement to help prevent repeat leaks or flow issues.
