Details on the 1 Row All Aluminum Product Line

The CSF 1 Row All Aluminum product line focuses on radiators constructed entirely from aluminum, including both the core and tanks. This design aligns with original equipment manufacturer (OEM) standards, providing reliable cooling performance and corrosion resistance. The single-row core design balances cooling efficiency with a compact size, making it suitable for the Toyota Sienna's engine bay requirements.

Technical Description of Radiator Part Number 3570

This radiator features a cross flow core layout, which allows coolant to flow horizontally through the core, improving heat exchange efficiency. The core thickness of 7/8 inch and dimensions of 19 5/16 inches wide by 26 5/16 inches long provide adequate surface area for heat dissipation. Both the core and tanks are made from aluminum, enhancing durability and reducing weight compared to traditional copper-brass radiators. The inlet and outlet diameters are sized at 1 3/8 inch (right) and 1 1/2 inch (left), respectively, ensuring compatibility with the Toyota Sienna's cooling system hoses. Additionally, the integrated high-efficiency plate type oil cooler (13 3/4 inches) supports engine oil temperature regulation.

Common Applications and Issues Addressed

  • Replacement for leaking or damaged Toyota Sienna radiators
  • Improves engine cooling efficiency in older or high-mileage vehicles
  • Resolves overheating issues caused by clogged or corroded radiator cores
  • Supports engine oil cooling to prevent overheating under heavy load
  • Restores proper coolant flow with OEM-style inlet and outlet fittings

Installation Notes and Tips

When installing the CSF radiator part number 3570 on a Toyota Sienna, ensure all hose connections match the specified inlet and outlet diameters. The cross flow design requires proper orientation for optimal coolant flow. It is recommended to inspect and replace radiator hoses and clamps during installation to prevent leaks. Since the radiator does not include a cap, reuse the existing radiator cap or source a compatible replacement. Verify coolant levels and bleed the cooling system after installation to avoid air pockets.
