Detailed Description of Radiator 2350

This radiator from One Stop Solutions is engineered with a crossflow core design that enhances cooling efficiency by allowing coolant to flow horizontally through the core. The core is constructed from PA material, which offers a balance of strength and heat transfer capability, while the plastic tanks reduce weight and resist corrosion. The integrated transmission oil cooler is plated and designed to fit Buick LeSabre and Park Avenue models, providing additional cooling for the transmission fluid to help maintain transmission performance and longevity. The radiator’s inlet and outlet headers measure 16 5/8" in length and 2 7/16" in width, ensuring compatibility with factory hoses and fittings. This radiator does not include an engine oil cooler or cap, focusing on essential cooling functions for the engine and transmission.

Common Issues Addressed by This Radiator

  • Overheating due to clogged or damaged radiator cores
  • Transmission fluid overheating affecting shifting performance
  • Leaks from cracked or worn plastic tanks
  • Reduced cooling efficiency from corrosion or core damage
  • Incompatibility or poor fit of aftermarket radiators causing installation issues

Installation Notes and Tips

Installation of the One Stop Solutions radiator 2350 is designed to be hassle-free with a drop-in fit for Buick LeSabre and Park Avenue vehicles. Ensure all factory fittings and hoses match the inlet and outlet diameters of 1 5/16" and 1 9/16" respectively. Verify the transmission oil cooler fittings align with the 11 1/2" spacing to avoid connection issues. While the radiator does not include a cap, reuse the original or source a compatible cap separately. Follow factory torque specifications when securing components to maintain proper sealing and function.
