Detailed Product Description

This One Stop Solutions radiator (part number 13425) is built with a 13 3/8 inch core height, 27 1/16 inch core width, and a core thickness of 5/8 inch, providing efficient heat dissipation. The radiator features a single core row constructed from PA material, combined with plastic tanks for a balance of weight and durability. Both the inlet and outlet headers measure 28 3/16 inches in length and 1 9/16 inches in width, with matching inlet and outlet diameters of 1 9/16 inches, ensuring proper coolant flow. The downflow design supports effective coolant circulation, optimized for Subaru Forester engine cooling requirements. This radiator does not include transmission or engine oil coolers, focusing solely on engine coolant management.

Compatible Applications and Common Issues Addressed

  • Replacement for leaking or cracked radiators in Subaru Forester models
  • Solves overheating problems caused by clogged or inefficient cooling cores
  • Addresses coolant flow restrictions due to damaged inlet or outlet headers
  • Resolves radiator core corrosion or physical damage from road debris
  • Improves cooling system reliability after original radiator failure

Installation Notes and Tips

Installation of the One Stop Solutions radiator 13425 is straightforward with a drop-in fit for Subaru Forester vehicles. Ensure all factory mounting points are aligned and torqued to manufacturer specifications. Verify that the inlet and outlet hoses match the 1 9/16 inch diameter connections. Since the radiator does not include a cap, reuse the existing cap or source a compatible replacement. Bleed the cooling system properly after installation to avoid air pockets and ensure optimal performance.

Quality Assurance and Testing

Each radiator undergoes rigorous testing up to three times during production to verify leak-free operation and structural integrity. Components such as tubes, fins, headers, and tanks are manufactured from premium materials and assembled to meet factory specifications. Engineering enhancements incorporated into this radiator address known design weaknesses, contributing to improved cooling efficiency and longer service life. While no specific warranty information is provided, the product is built to meet or exceed OEM standards for Subaru Forester cooling systems.
