Detailed Product Description

The CSF 3459 radiator belongs to the 1 Row Plastic Tank Aluminum Core product line, which combines lightweight aluminum cores with durable plastic tanks to provide effective heat dissipation and corrosion resistance. This radiator features a cross flow design that enhances coolant flow across the core, improving heat exchange efficiency. The 1 1/4 inch thick aluminum core measures 16 7/8 inches wide and 25 11/16 inches long, providing a compact yet effective cooling surface. The plastic tanks are designed to match OEM specifications and include quick-connect inlet fittings for easier installation. The inlet is positioned on the left side with a 1 1/4 inch diameter, while the outlet is on the right side with the same diameter, ensuring compatibility with factory coolant lines.

Compatible Vehicles and Applications

This radiator is compatible with a range of Audi and Volkswagen vehicles, including the Audi A3, A3 Quattro, and TT, as well as Volkswagen Beetle, Eos, Golf, Golf City, Jetta, Jetta City, and Passat models. It is designed to replace original equipment radiators in these vehicles, maintaining proper engine cooling and performance.

  • Overheating issues due to radiator core damage or clogging
  • Coolant leaks from cracked or worn plastic tanks
  • Reduced cooling efficiency from corrosion or core blockage
  • Replacement of damaged or faulty OEM radiators
  • Maintaining engine temperature stability in Audi A3 and Volkswagen Golf models

Installation Notes and Tips

When installing the CSF 3459 radiator, ensure the vehicle is fully cooled and the cooling system is depressurized. Verify that the inlet and outlet hose diameters match the radiator connections (1 1/4 inch). The quick-connect inlet fittings simplify hose attachment but confirm secure connections to prevent leaks. It is recommended to flush the cooling system before installation to remove debris and contaminants. Properly torque mounting hardware and refill the system with the correct coolant mixture to OEM specifications.
