Product Description

The CSF 2607 is a direct OEM replacement radiator engineered for the 1995-2000 Lexus LS400 equipped with the 4.0L V8 1UZ-FE engine. This 1-row plastic tank and aluminum core radiator is built to match the factory radiator's exact dimensions, mounting points, and hose connections for a true drop-in installation with no modifications required. CSF manufactures this radiator in ISO/TSO-certified facilities using the same materials and construction methods as the original equipment unit, ensuring seamless integration with the LS400's cooling system and all associated OEM components including the fan shroud, hose connections, and mounting brackets.

The aluminum core features CSF's high-performance multi-louvered fin design - carefully measured and calculated for this specific application and validated in CSF's wind tunnel laboratory for optimal heat rejection efficiency. The plastic tanks are manufactured from virgin-grade engineered resins that are glass-filled for superior strength and resistance to cracking over time - a common failure point on aging OEM and low-quality aftermarket radiators. Special-grade EPDM rubber gaskets rated to -120°F provide a reliable seal between the tanks and core. A high-performance transmission cooler with a built-in turbulator is integrated into the tank for enhanced automatic transmission fluid cooling, maintaining proper ATF temperatures under all driving conditions.

Every CSF 2607 radiator is individually leak tested at the factory at 150% of operating pressure before it leaves the production line, and undergoes additional vibration-cycle, thermal-cycle, burst pressure, impulse-cycle, and salt spray testing during the development process. CSF has manufactured radiators for over 50 years with more than 30 million units sold worldwide, and their rigorous 30-point fitment inspection process ensures that every radiator meets the exact specifications required for a trouble-free installation. Whether you are replacing a leaking or clogged factory radiator or performing preventive maintenance on your LS400, the CSF 2607 delivers OEM-quality cooling performance, fit, and reliability backed by CSF's reputation as the industry leader in aftermarket radiator manufacturing.
