• Built to meet ISO 7637, ISO 16750, and EMC requirements

Product Details

Nissens 850554 is a dual radiator and condenser fan assembly engineered for vehicles that require coordinated cooling across the radiator and A/C condenser. The assembly uses two clockwise-rotating fans, a plug-in connection style, and a shroud to support consistent airflow through the cooling stack. For Lexus RX350 and Toyota Sienna applications, this configuration helps restore proper thermal management when the original fan assembly is worn, noisy, or no longer operating correctly.

Nissens cooling fan assemblies are built with OE-level control electronics and compliance-focused electrical design. The 850554 part number is also referenced by OE-style interchange numbers including 163630P100 and 1636331330, making it easier to verify the correct replacement during parts lookup.

What It Helps Fix

• Overheating caused by a failed cooling fan assembly
• Weak airflow through the radiator and condenser
• Intermittent fan operation from electrical control issues
• Noisy or unbalanced fan performance
• Cooling-system service needs on vehicles without the towing package

Installation Notes

Verify connector style, fan rotation, and vehicle configuration before installation. This assembly uses plug-in connectors and does not include a wiring harness, control unit, or resistor. Confirm fitment for the correct Lexus RX350 or Toyota Sienna application, including the note for vehicles without the towing package.

Quality Assurance

Nissens designs its fan assemblies to meet OE requirements and electrical compatibility standards, including ISO 7637, ISO 16750, and EMC compliance. The 850554 is engineered for stable, long-life cooling performance in normal service conditions.
