Details on the 1 Row Plastic Tank Aluminum Core Product Line

The CSF 1 Row Plastic Tank Aluminum Core product line combines OEM-style plastic tanks with a robust aluminum core to balance durability and weight. This design supports effective cooling while maintaining compatibility with factory mounting points and hose connections. The single-row core thickness of 5/8 inch and down flow configuration optimize coolant flow for Subaru vehicles requiring precise thermal management.

Technical Description and Specifications

This radiator features a 5/8 inch thick aluminum core measuring 27 inches wide by 13 3/8 inches long, providing a solid surface area for heat exchange. The plastic tanks reduce overall weight without compromising structural integrity. Both the inlet and outlet have a diameter of 1 9/16 inches located on the left side, facilitating straightforward installation. The down flow design promotes efficient coolant circulation through the single-row core. Additionally, the integrated 14 3/4 inch high-efficiency plate type oil cooler enhances engine oil temperature regulation, contributing to overall engine performance.

Common Applications and Problem Resolution

  • Replacement for leaking or damaged radiators in Subaru Legacy and Outback
  • Improves engine cooling efficiency to prevent overheating
  • Restores proper coolant flow with OEM-style plastic tanks and aluminum core
  • Addresses radiator core corrosion or clogging issues

Installation Notes and Tips

When installing the CSF 3500 radiator, ensure compatibility with your Subaru Legacy or Outback model year and engine configuration. The radiator’s OEM-style plastic tanks and aluminum core allow for direct replacement without modification. Verify inlet and outlet hose diameters (1 9/16 inches, left side) match your vehicle’s hoses. Since the radiator does not include a cap, reuse the existing cap or purchase separately (CSF cap number 4503). Properly bleed the cooling system after installation to avoid air pockets and ensure optimal performance.
