Features:

• 100% factory tested for leakage and dimensional precision.
• Bearing noise and durability-tested.
• Designed to match OE coolant flow rate and pressure.
• All required hardware included for easy installation.
• Engineered to respond precisely to under-hood temperature changes, the clutch automatically adjusts fan engagement to maintain ideal operating conditions in a wide range of driving environments.
• During colder starts, reduced fan engagement allows the engine to reach optimal temperature faster, supporting better fuel efficiency and improved heater performance.
• When higher temperatures are detected, the clutch smoothly increases fan speed to provide enhanced airflow across the radiator, helping prevent overheating during towing, stop-and-go traffic, or extreme weather conditions.
