CSF 3763 radiator replacement is designed for drivers servicing Lexus ES300h, Lexus ES350, Toyota Avalon, and Toyota Camry cooling systems. The aluminum core helps transfer heat efficiently, while the plastic tank construction follows an OE-style layout for a familiar factory fit. This radiator is a practical choice when replacing a leaking, clogged, or damaged unit on 2012-2018 vehicles in the listed applications.

This part cross-references Spectra Premium CU13270 and Bosch 13338 for the same application.

Common Cooling System Issues It Can Address

• Coolant leaks from a cracked or aging radiator tank
• Restricted coolant flow caused by internal buildup
• Overheating from reduced heat dissipation
• Temperature instability during stop-and-go driving
• Replacement needs after collision or front-end damage

Installation Notes and Tips

Verify radiator dimensions, inlet and outlet location, and vehicle build details before installation. This unit uses a down-flow configuration with center inlet and right-side outlet, so matching hose routing is important. Inspect hoses, clamps, and coolant condition during replacement to help complete the repair correctly.
