Details on the 1 Row Plastic Tank Aluminum Core Product Line

The CSF 1 Row Plastic Tank Aluminum Core product line combines lightweight plastic tanks with a robust aluminum core to balance durability and heat transfer efficiency. This design is tailored for vehicles like the Honda Fit that require dependable cooling with a compact, single-row core. The plastic tanks reduce weight and resist corrosion, while the aluminum core ensures effective heat dissipation under normal driving conditions.

Product Description and Specifications

The CSF 3370 radiator features a 5/8 inch thick aluminum core measuring 25 11/16 inches wide and 12 3/4 inches long, providing a solid surface area for heat exchange. The radiator is configured as a down flow type, which directs coolant downward through the core for consistent temperature regulation. The inlet and outlet diameters are both 1 1/8 inches, positioned on the left and right sides respectively, matching OEM specifications for the Honda Fit. Additionally, this radiator includes a 7 7/8 inch high-efficiency plate type oil cooler integrated into the design, enhancing engine cooling performance.

Common Applications and Problem Solving

  • Replacement for leaking or damaged Honda Fit radiators
  • Resolves overheating issues caused by inefficient cooling
  • Addresses coolant leaks from cracked plastic tanks
  • Improves engine temperature stability during extended driving
  • Restores OEM cooling system performance after radiator failure

Installation Notes and Tips

When installing the CSF 3370 radiator, ensure compatibility with the Honda Fit model year and engine configuration. Properly drain the cooling system before removal and inspect hoses and clamps for wear. Align the inlet and outlet connections carefully to avoid leaks. Since the radiator does not include a cap, reuse the existing OEM cap or source a compatible replacement. Bleed the cooling system thoroughly after installation to prevent air pockets.
