Product Details

This Universal Air radiator is built for the cooling system layout used in the 2006-2013 Lexus IS250 and 2006-2013 Lexus IS350. As a downflow radiator, it is specified for vehicles that use a vertical coolant flow path through the core, which is important when matching the replacement part to the original cooling system configuration. Search terms such as Lexus IS250 radiator replacement, Lexus IS350 downflow radiator, and RA2968C radiator fitment all point to this application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Cooling System Issues

• Coolant leaks from a damaged or corroded radiator
• Overheating caused by restricted coolant flow
• Temperature instability during stop-and-go driving
• Reduced cooling performance from an aging radiator core
• Replacement need after impact damage to the front cooling stack

Installation Notes

Verify the vehicle’s original radiator style and mounting layout before installation. Confirm fitment against the existing cooling system configuration on your Lexus IS250 or Lexus IS350, and inspect hoses, clamps, and related cooling components during replacement. Use the part number RA2968C to confirm the correct application before ordering.
