Detailed Description

The RA13630C is a replacement radiator from Universal Air’s Downflow Radiator line, engineered for the listed INFINITI Q50 and INFINITI Q60 applications.

What It Helps Address

  • Cooling-system leaks from a damaged radiator core or tank.
  • Overheating caused by restricted coolant flow through the radiator.
  • Fitment issues when replacing a radiator with the wrong configuration.
  • Service needs on vehicles that require a downflow radiator layout.
