Detailed Description

OSC part number 2058 is a direct-fit radiator for Lexus LS400 models from 1995 through 2000. It is engineered around OE-style dimensions and cooling layout, with a downflow configuration, integrated concentric transmission oil cooler, and factory-style header and tank construction. The radiator is designed to maintain proper coolant flow and heat transfer while preserving fitment in the engine bay.

OSC uses premium materials and production checks to help reduce premature failure. The radiator core is pressure tested before assembly, the cooler circuits are tested before installation into the tank, and the completed unit is tested again. This makes 2058 a practical replacement for a worn or leaking Lexus LS400 radiator when restoring cooling system performance.

This part cross-references Spectra Premium CU2058 and Koyorad A2058 for the same application.

What It Helps Fix

• Coolant leaks from a cracked or aging radiator
• Overheating caused by restricted heat transfer
• Transmission fluid temperature issues related to the built-in cooler
• Fitment problems from a damaged or incorrect replacement radiator
• Cooling system wear on high-mileage Lexus LS400 vehicles

Installation Notes and Tips

Verify inlet and outlet hose sizes, cooler line routing, and overall core dimensions before installation. Replace worn hoses, clamps, and coolant as needed, and inspect the fan, thermostat, and water pump if the vehicle has a history of overheating. This radiator is a direct replacement for Lexus LS400 applications listed above, and part number 2058 should be matched to the vehicle’s original cooling configuration.

Quality Assurance

OSC builds this radiator to OE-style form and function using premium-grade materials and factory-spec assembly practices. Each unit is pressure tested during production, and the design includes enhancements aimed at improving durability and cooling performance in higher-mileage vehicles.
