Four Seasons 46064 Thermal Engine Cooling Fan Clutch

The Four Seasons 46064 is a thermal engine cooling fan clutch engineered as a direct OE replacement for vehicles requiring a reliable, factory-equivalent fan drive solution. As part of Four Seasons' comprehensive cooling system line — a division of Standard Motor Products — this fan clutch is precision-manufactured to restore proper engine temperature management and prevent overheating.

A thermal fan clutch works by using a bimetal spring to sense air temperature passing through the radiator. At lower temperatures, the clutch allows the fan to freewheel, reducing parasitic drag and engine noise. As temperatures rise, the clutch engages more fully, increasing fan speed to draw additional airflow through the radiator and maintain safe operating temperatures.

Key Features:

• Precision-engineered to meet or exceed original equipment (OE) specifications
• Thermally activated for automatic, temperature-responsive fan engagement
• Manufactured to strict quality standards for consistent fit and performance
• Designed for straightforward installation with exact OE dimensions
• Backed by Four Seasons' limited 12-month / 12,000-mile warranty on fan clutches
• Produced by Four Seasons, a division of Standard Motor Products — the largest aftermarket mobile climate control parts supplier in the industry

Replacing a worn or failed fan clutch promptly is critical to engine health. A failing fan clutch can cause overheating, reduced A/C performance, and increased engine wear. The Four Seasons 46064 provides a dependable, cost-effective replacement that restores your cooling system to proper operating condition.
