Detailed Description

CSF 3792 is designed for drivers needing a direct replacement radiator that matches the original cooling layout. The aluminum core helps transfer heat efficiently, while the plastic tanks follow the OE-style construction used on many factory radiators. With a cross-flow configuration, 27 1/2 in. core length, and 16 5/8 in. core width, this radiator is built around the dimensions needed for proper fitment in the Lexus NX platform. This part cross-references Bosch 13514 for the same application.

Compatible With 2018-2021 Lexus NX300 and 2015-2017 Lexus NX200t, CSF 3792 supports routine radiator replacement when the original unit is leaking, restricted, or no longer maintaining stable coolant temperatures. The part number 3792 is also useful when searching for an OE-style Lexus NX300 radiator or Lexus NX200t radiator replacement.

Common Cooling System Issues

• Coolant leaks from a cracked or aging radiator tank
• Overheating caused by reduced heat transfer through the core
• Restricted coolant flow from internal buildup or corrosion
• Temperature instability during stop-and-go or highway driving
• Replacement needs after impact damage to the radiator assembly

Installation Notes and Tips

Verify inlet and outlet orientation before installation: this radiator uses a left-side inlet and right-side outlet. Confirm core dimensions, hose routing, and mounting points against the original unit before removal. Transfer any vehicle-specific components required by the application and inspect hoses, clamps, and coolant condition during service.
