Details on the 1 Row Plastic Tank Aluminum Core Product Line

The CSF 1 Row Plastic Tank Aluminum Core line combines lightweight plastic tanks with a robust aluminum core to balance durability and heat transfer efficiency. This product line is engineered to meet OEM specifications, ensuring compatibility and performance for vehicles like the Chevrolet Sonic. The single-row core design supports effective cooling while maintaining a compact profile suitable for tight engine compartments.

Product Description and Specifications

The CSF 3734 radiator features a 7/8 inch thick aluminum core measuring 15 5/8 inches wide and 24 7/16 inches long. Its cross flow configuration enhances coolant flow across the core, improving heat exchange. The plastic tanks reduce weight and resist corrosion, while the inlet and outlet diameters (1 3/8 inches left inlet and 1 1/2 inches right outlet) are designed for direct fitment on Chevrolet Sonic models. The radiator also includes a high-efficiency 11 1/2 inch plate-type oil cooler integrated into the assembly, supporting engine oil temperature regulation.

Common Applications and Issues Addressed

  • Replacement for leaking or damaged radiators on Chevrolet Sonic vehicles
  • Resolves overheating caused by clogged or inefficient cooling cores
  • Addresses coolant leaks from cracked plastic tanks
  • Improves engine oil cooling with integrated oil cooler
  • Restores proper coolant flow with OEM-style quick-connect fittings

Installation Notes and Tips

Installation of the CSF 3734 radiator requires draining the existing coolant and removing the old radiator assembly. Ensure all hose connections match the 1 3/8 inch inlet and 1 1/2 inch outlet diameters. The cross flow design requires proper orientation for optimal coolant circulation. Use OEM recommended coolant and verify no leaks after installation. The radiator does not include a cap, so reuse the existing cap or purchase separately if needed.

CSF radiators are manufactured to meet OEM standards for fit, form, and function. The 3734 radiator is constructed with corrosion-resistant aluminum core and durable plastic tanks to provide long service life.
