Detailed Description

OSC part number 13019 is a replacement radiator engineered for the Lexus RX350 cooling system. It uses premium-grade aluminum construction with plastic tanks and is built to match original equipment fit and function. The radiator includes a plated transmission oil cooler and is designed with factory-style dimensions, including 20 in. inlet and outlet header lengths and 13 3/4 in. cooler fitting spacing. For buyers searching for a 2007 Lexus RX350 radiator, 2008 Lexus RX350 radiator, or 2009 Lexus RX350 radiator, this unit provides a direct-fit solution with OE-style packaging and cooling layout.

OSC builds this radiator with enhanced internal components to improve durability and cooling consistency. The core is pressure tested before and after assembly, and the completed unit is tested again during production. This helps verify sealing and cooler integrity before installation. Part number 13019 also cross-references Spectra Premium CU13019 for the same application.

Common Cooling Issues It Can Address

• Coolant leaks from a damaged or aging radiator tank or core
• Overheating caused by reduced heat transfer efficiency
• Transmission fluid temperature concerns tied to a failing integrated cooler
• Cracked or weakened radiator components from long-term heat cycling
• Poor fitment or sealing from a non-OE-style replacement radiator

Installation Notes and Tips

Verify hose size, cooler line routing, and mounting points against the original radiator before installation. This radiator is designed for drop-in fitment on the listed Lexus RX350 applications, and the OE-style dimensions help simplify replacement. Inspect related cooling system parts such as hoses, clamps, and the radiator cap condition during service, since the cap is not included.

Quality Assurance

OSC uses factory-style engineering, pressure testing, and cooler verification during production to help maintain consistent quality. The radiator is built to OE form and function standards for the 2007-2009 Lexus RX350 platform and is assembled with components selected for durability and leak resistance.
