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.

The 1-row core configuration is suitable for vehicles like the Honda HR-V that require efficient cooling without added bulk.

Technical Description of the CSF 3854 Radiator

This radiator features a 5/8 inch thick aluminum core measuring 14 3/4 inches wide and 26 3/8 inches long, providing a solid surface area for heat exchange. The plastic tanks reduce weight and resist corrosion, while the down flow design ensures coolant flows from top to bottom, optimizing thermal management. Both the inlet and outlet have a 1 1/4 inch diameter and are located on the left side, matching the Honda HR-V’s factory specifications. The radiator does not include a cap, so the existing cap should be reused or replaced separately.

Common Applications and Problem Solving

  • Replacement for leaking or damaged Honda HR-V radiators
  • Restores proper engine cooling to prevent overheating
  • Addresses coolant flow issues related to core or tank failure
  • Suitable for vehicles requiring a down flow, single-row radiator
  • Compatible with Honda HR-V models needing OEM-style plastic tank radiators

Installation Notes and Tips

Ensure the radiator is compatible with your specific Honda HR-V model year before installation. Since the radiator does not include a cap, retain your existing radiator cap or purchase a compatible replacement. Verify hose connections match the 1 1/4 inch inlet and outlet diameters on the left side. Properly bleed the cooling system after installation to avoid air pockets and ensure optimal performance.
