Detailed Description

This radiator is built to match OE form and function for the Lexus LS430 cooling system. OSC uses premium-grade aluminum tubes and cadmium-plated internal and external tube surfaces to help resist premature failure, while the factory-style plastic tanks and fitted components support a clean installation and proper sealing. Part Number 2419 is also cross-referenced with Spectra Premium CU2419 for the same application.

The radiator includes a concentric transmission oil cooler and is engineered for multi-fit use without changing the appearance or fit of the original cooling assembly. The core measures 16 3/4 inches high by 29 13/16 inches wide, with a 1-inch core thickness and 1-row construction. This makes it a direct replacement choice for 2001-2006 Lexus LS430 cooling system service where OE-style dimensions and cooler integration matter.

Common Problems This Radiator Can Address

• Coolant leaks from a worn or damaged radiator tank or seal
• Overheating caused by reduced cooling efficiency
• Transmission fluid temperature issues related to a failing cooler circuit
• Corrosion or fatigue in aging radiator tubes and headers
• Poor fitment from non-OE-style replacement parts

Installation Notes and Tips

Verify the radiator dimensions, inlet and outlet sizes, and transmission cooler layout before installation. This unit is designed for the 2001-2006 Lexus LS430, N/A, and should be matched to the vehicle’s original cooling configuration. Inspect hoses, clamps, and related cooling components during replacement to help ensure proper sealing and system performance.

Quality Assurance

OSC tests the transmission and engine oil coolers before tank installation, checks the radiator core prior to assembly, and tests the completed unit again after assembly. Each radiator is individually pressure tested, and the design includes factory-style fitted components and a die-cut gasket to support leak resistance and consistent OE-style performance.
