About the 1 Row Plastic Tank Aluminum Core Brand Line

The CSF 1 Row Plastic Tank Aluminum Core product line combines OEM-style plastic tanks with a robust aluminum core to deliver dependable cooling performance. This line is engineered to meet factory specifications, ensuring compatibility and durability for vehicles like the Mitsubishi Outlander. The single-row core design balances cooling efficiency with a compact form factor suitable for various engine compartments.

Detailed Product Description

The CSF 3129 radiator features a 7/8 inch thick aluminum core that measures 27 1/16 inches wide and 16 3/4 inches long, providing a solid surface area for heat exchange. The plastic tanks are designed to withstand typical operating conditions while reducing weight. The radiator uses a down flow design, directing coolant from the top to the bottom, which is common in many Mitsubishi Outlander cooling systems. Both the inlet and outlet have a diameter of 1 3/8 inches, positioned center and left respectively, to match OEM hose connections. Additionally, the integrated high-efficiency concentric oil cooler enhances engine oil temperature regulation.

Common Applications and Issues Addressed

  • Replacement for leaking or cracked radiators in Mitsubishi Outlander vehicles
  • Restores proper engine cooling to prevent overheating
  • Addresses reduced cooling efficiency due to clogged or damaged cores
  • Suitable for vehicles requiring a down flow radiator configuration
  • Compatible with Mitsubishi Outlander models needing a 1-row aluminum core radiator

Installation Notes and Tips

Ensure the radiator core dimensions and inlet/outlet positions match your Mitsubishi Outlander’s specifications before installation. This radiator does not include a cap, so reuse the existing cap or purchase a compatible CSF cap number 4503 separately. Properly bleed the cooling system after installation to avoid air pockets and ensure optimal performance.
