Detailed Radiator Specifications and Construction

This radiator features a downflow design with a single core row, measuring 28 1/4 inches in width, 16 3/4 inches in height, and 1 inch in thickness. The core is constructed from PA material, paired with durable plastic tanks to resist corrosion and wear. Both inlet and outlet headers measure 29 1/8 inches in length and 2 inches in width, with inlet and outlet diameters of 1 1/4 inches, ensuring proper coolant flow. The included concentric transmission oil cooler has a diameter of 3/4 inch and a fitting distance of 14 3/4 inches, supporting transmission fluid cooling without an engine oil cooler. This radiator is engineered to meet the specific cooling demands of the Acura RL, maintaining engine temperature stability and transmission efficiency.

Common Issues Addressed by This Radiator

  • Overheating due to radiator core damage or clogging
  • Coolant leaks from cracked or worn plastic tanks
  • Transmission fluid overheating without an integrated cooler
  • Reduced cooling efficiency from original radiator design limitations
  • Premature radiator failure caused by substandard materials

Installation Notes and Tips

Installation of the One Stop Solutions radiator 2838 is straightforward with a direct fit design for Acura RL models. Ensure all factory specifications for torque are followed when securing components. Verify that the transmission oil cooler fittings are properly connected to avoid leaks. Since the radiator does not include a cap, reuse the existing cap or replace it separately if needed. Inspect hoses and clamps during installation for wear or damage to maintain system integrity.

Quality Assurance and Testing

Each radiator undergoes rigorous testing up to three times during production to verify leak resistance and cooling performance. Components are assembled and torqued to factory specifications to ensure durability and reliability. The use of premium grade tubes, fins, headers, and tanks contributes to the radiator’s longevity. While no specific warranty information is provided, the product is manufactured to meet or exceed OEM standards for Acura RL cooling systems.
