Restore stable engine cooling with this direct-fit replacement radiator for select Toyota Sienna and Lexus RX350 models. Designed for compatible 2.7L and 3.5L applications, it uses an aluminum-core construction and OE-style mounting points to replace a leaking, clogged, corroded, or damaged factory radiator. The radiator helps maintain proper engine operating temperature during daily driving, highway use, family travel, and warm-weather conditions. 

Vehicle Fitment & OE Reference Numbers

OE / Interchange Reference Numbers: CU13116, 13116, 13206, 13207, 16041-0P260, TO3010330, RAD13206.

Before ordering: Compare the OE number, overall dimensions, inlet and outlet positions, mounting points, drain location, and fan shroud mounting configuration with the original radiator.

Product Specifications & Package Includes

Package Includes: 1 × replacement radiator and 1 × instruction manual.

Signs Your Radiator Needs Replacement

• The engine temperature runs higher than normal or the vehicle overheats.
• Coolant leaks appear around the radiator, end tanks, hose connections, drain area, or lower corners.
• The coolant level drops repeatedly without an obvious hose leak.
• Plastic end tanks are cracked, swollen, discolored, or separating from the core.
• Cooling fins are bent, clogged, corroded, or damaged.
• The temperature gauge fluctuates during city driving, idling, or warm-weather use.

Replacing a worn or damaged radiator helps restore coolant flow and heat transfer, reducing the risk of repeated overheating and related engine damage.

Key Features & Benefits

Stable Daily Cooling: Helps maintain engine temperature during commuting, highway driving, family travel, idling, and warm-weather operation.

OE-Reference Fitment: Built to match compatible factory radiator locations and simplify installation when the correct configuration is selected.

Built for Replacement Service: Suitable for replacing radiators affected by leaks, internal blockage, damaged fins, corrosion, cracked tanks, or weakened seals.

Installation Notes & 4-Step Guide

Important: The cooling system may be pressurized and contain hot coolant. Allow the engine to cool completely before beginning. Professional installation is recommended if you are not experienced with cooling-system service.

1. Drain: Disconnect the battery if required, remove the radiator cap only after the engine has fully cooled, and drain the old coolant into a suitable container.
2. Remove: Disconnect the upper and lower radiator hoses, overflow hose, fan shroud or fan assembly, and factory mounting hardware. Remove the old radiator carefully.
3. Install: Compare both radiators before fitting. Transfer reusable brackets, cushions, drain plugs, sensors, fittings, or fan shroud hardware when required, then install the new radiator using the factory mounting points.
4. Refill & Bleed: Reconnect all hoses, refill with the vehicle manufacturer-recommended coolant mixture, bleed trapped air from the cooling system, and inspect all connections for leaks.

After installation: Inspect the radiator hoses, clamps, cap, thermostat, cooling fan, coolant reservoir, and water pump. Run the engine until operating temperature is reached, confirm fan operation, check all connections for leakage, and recheck the coolant level after the first drive and again after the engine cools.
