Detailed Product Description

This One Stop Solutions radiator (part number 2859) is engineered to meet the cooling demands of Mini Cooper vehicles. Featuring a crossflow core with a height of 22 5/8 inches, width of 15 11/16 inches, and a thickness of 1 inch, it provides effective heat exchange to maintain optimal engine temperature. The core is constructed from PA material, paired with plastic tanks, offering a balance of lightweight design and resistance to corrosion. Both inlet and outlet headers measure 16 9/16 inches in length and 1 13/16 inches in width, with 1 1/4 inch diameter connections, ensuring compatibility with Mini Cooper coolant lines. This radiator does not include transmission or engine oil coolers, focusing solely on engine coolant management. The single core row design supports efficient coolant flow and heat dissipation, tailored for the Mini Cooper's engine bay layout.

Common Applications and Issues Addressed

  • Replacement for leaking or damaged radiators in Mini Cooper models
  • Resolves overheating issues caused by inefficient or clogged radiators
  • Addresses coolant loss due to cracked or corroded radiator tanks
  • Improves engine cooling performance after original radiator failure
  • Suitable for restoring factory cooling system specifications in Mini Cooper vehicles

Installation Notes and Tips

Installation of the One Stop Solutions radiator 2859 is designed to be hassle-free with a drop-in fit for Mini Cooper models. Ensure all coolant lines and connections match the 1 1/4 inch inlet and outlet diameters. Verify that the radiator mounts align with factory points and torque fittings to manufacturer specifications. Since this radiator does not include a cap or transmission oil cooler, reuse existing components or source separately as needed. Proper bleeding of the cooling system after installation is recommended to avoid air pockets and ensure optimal performance.

Quality Assurance and Warranty

Each radiator undergoes up to three quality tests during production to verify performance and durability. The product is engineered with premium grade tubes, fins, headers, and tanks to meet or exceed original equipment standards. While specific warranty details are not provided, One Stop Solutions products are manufactured to comply with factory specifications and quality benchmarks for Mini Cooper cooling components.
