Lexus NX300h Dual Radiator and Condenser Fan Assemblies
Lexus Nx300H Dual radiator and condenser fan assemblys
Starting at $228.95, AutoBuffy stocks 2 dual radiator and condenser fan assemblies from APDI and TYC. This combined electric fan unit pulls air through both the radiator and AC condenser when the vehicle is stationary or moving slowly. When it fails, coolant temperatures spike, AC performance drops, and the engine risks serious heat damage.
Signs your Lexus Nx300H needs a new dual radiator and condenser fan assembly
- Engine temperature gauge climbs into the red during stop-and-go traffic or idling but returns to normal at highway speeds
- AC blows warm or noticeably weaker air when the vehicle is stopped, even with the compressor clutch engaged
- Cooling fan motor runs constantly at full speed or does not spin at all when the engine reaches operating temperature
- Audible grinding, rattling, or buzzing from behind the grille caused by worn fan motor bearings or a cracked/unbalanced blade
- Radiator fan error code or electric fan circuit fault stored in the ECM (common codes include P0480, P0481, P0483)
- Coolant overflow reservoir boils over or steam rises from under the hood while idling with the AC on
Which dual radiator and condenser fan assembly should you buy for your Lexus Nx300H?
The most important decision is matching the assembly to your vehicle's exact cooling system configuration — motor speed, shroud dimensions, connector type, and whether your Lexus Nx300H uses a single-speed or variable-speed fan circuit all affect fitment and function. OE-replacement assemblies that include the shroud, motor, and blades as a complete unit are strongly preferred over sourcing components separately, since blade pitch and shroud geometry are calibrated together from the factory.
OE-Replacement (complete assembly)
Best for
Drivers who want a direct, no-modification swap with factory-level cooling performance
What you get
Pre-assembled shroud, motor, blades, and wiring pigtail engineered to factory specs — plug-and-play installation
Economy / Value-Line Assembly
Best for
High-mileage vehicles or budget-conscious repairs where longevity is a secondary concern
What you get
Functional replacement at a lower price point; shorter warranty, may use lower-grade motor windings — acceptable for older Nx300Hs
Heavy-Duty / Performance Assembly
Best for
Towing, performance builds, or Lexus Nx300Hs in hot climates with upgraded cooling needs
What you get
Higher CFM output, reinforced motor, and sometimes dual independent motors for more aggressive heat rejection
Condenser Fan Only (separate motor)
Best for
Cases where only one motor in a dual-motor setup has failed and the shroud is undamaged
What you get
Replacement motor and blade for the AC-side fan; saves cost if the radiator fan motor and shroud are confirmed good

Replacing a dual radiator and condenser fan assembly on a Lexus Nx300H
Moderate⏱ 1–2 hoursSocket set with extensions (metric and SAE)Flathead and Phillips screwdriversPlastic trim clip remover / pry toolNeedle-nose pliers (for wiring harness clips)Drain pan (if partial coolant drainage is required for access)
Begin by disconnecting the negative battery terminal and allowing the engine to cool completely, then unplug the fan motor electrical connectors and release any wiring harness clips securing the loom to the shroud. Remove the mounting bolts or tabs anchoring the assembly to the radiator support, slide the unit up and out of its lower retaining slots, and transfer any remaining brackets or grounding straps to the new assembly before reversing the steps. Reconnect the battery, start the engine, and confirm the fan engages at the correct coolant temperature and again when the AC is switched on.
Frequently asked questions
How much does it cost to replace dual radiator and condenser fan assemblies on a Lexus Nx300H?
Parts start at $228.95 for a complete assembly on a Lexus Nx300H. Add $80–$200 for shop labor if you're not doing it yourself — most independent mechanics can complete the job in one to two hours. Total out-of-pocket cost varies based on the assembly grade you choose and your local labor rate.
Can I drive my Lexus Nx300H with a failed radiator and condenser fan assembly?
Short highway trips at speed may be possible because ram airflow cools the radiator without the fan, but stop-and-go driving or idling with a failed assembly risks rapid overheating. Sustained high coolant temperatures can warp cylinder heads or cause gasket failure. Avoid driving the Lexus Nx300H until the assembly is replaced.
Will a bad dual fan assembly affect my Lexus Nx300H's AC performance?
Yes. The condenser relies on the fan assembly to dissipate heat from refrigerant when the vehicle is not moving. A failed fan causes high-side pressure to spike, which either trips the AC pressure cutoff switch — shutting the compressor off — or results in warm, low-flow air from the vents even when the system is fully charged.
How do I know if the fan motor is bad or if it's a relay, fuse, or wiring issue on my Lexus Nx300H?
Apply 12V directly to the fan motor connector with jumper wires. If the fan spins normally, the motor is good and the fault lies in the relay, fuse, cooling fan control module, or wiring harness. If the motor hums without spinning, spins slowly, or does nothing, the motor itself has failed and the assembly needs replacement.
Does the dual fan assembly on a Lexus Nx300H come with the shroud, or do I need to buy that separately?
Most complete assemblies sold for the Lexus Nx300H include the shroud, motor, blades, and wiring pigtail as a single unit. Verify the product listing confirms 'complete assembly' before ordering. Buying a motor-only replacement is only practical if your existing shroud and blade are physically undamaged and confirmed to be the correct part.
How long does a dual radiator and condenser fan assembly typically last on a Lexus Nx300H?
Most assemblies last somewhere between 100,000 and 150,000 miles under normal conditions, though motor bearings can wear sooner in extreme heat climates or on vehicles that spend significant time idling. Coolant leaks that splash onto the motor can also accelerate failure. Replacement intervals vary widely by driving environment and assembly quality.
