OEM Aisin Fan Clutch
Fits Toyota 1KZ-T & 1KZ-TE Diesel Engines
Genuine Aisin • Made in Japan • OEM Toyota Quality
Keep your Toyota diesel running at the correct operating temperature with this Genuine OEM Aisin Fan Clutch, manufactured in Japan to Toyota’s exact specifications. As Toyota’s original equipment supplier, Aisin fan clutches are engineered for dependable cooling performance, long service life, and factory-correct operation.
Designed specifically for Toyota vehicles equipped with the 1KZ-T and 1KZ-TE diesel engines, this fan clutch provides reliable airflow through the radiator whenever additional cooling is required.
A viscous fan clutch is a thermostatically controlled silicone fluid coupling that automatically regulates cooling fan speed based on engine temperature. When the engine is cool, the clutch allows the fan to freewheel, reducing engine load, fan noise, and unnecessary power loss. As temperatures increase, the clutch progressively engages the mechanical fan, delivering increased airflow through the radiator to maintain proper engine operating temperatures.
Replacing a worn or faulty fan clutch helps restore factory cooling performance and can prevent overheating caused by insufficient fan engagement.
For maximum cooling performance, pair it with our HiYota 10-Blade High-Flow Cooling Fan.
