How This Radiator Works

The radiator removes heat from engine coolant as it passes through the core, then releases that heat to the air stream. On the Lexus RX400h and Toyota Highlander, a properly functioning radiator helps maintain stable operating temperatures, supports consistent engine performance, and reduces the risk of overheating during daily driving or stop-and-go use. Global Parts 2929C is built around the listed core dimensions and hose connections to match the cooling system layout of the confirmed applications.

Common Problems It Can Address

• Coolant leaks from a damaged or corroded radiator
• Overheating caused by restricted heat transfer
• Cracked plastic tanks or weakened seams
• Reduced cooling efficiency from internal blockage
• Temperature instability in hybrid SUV cooling systems

Installation Notes

Verify core size, inlet and outlet diameters, and hose routing before installation. Inspect the cooling system, radiator cap, hoses, and clamps for wear before replacing the radiator. Flush the system if contamination or debris is present, and refill with the correct coolant specification for the vehicle. After installation, bleed air from the system and confirm there are no leaks.

Quality Assurance

Global Parts supplies replacement cooling components for service applications, and this radiator is built to the listed dimensions and material specifications for the confirmed fitments. Part number 2929C is intended for direct replacement use on the listed Lexus RX400h and Toyota Highlander models.
