Four Seasons 36994 Reverse Rotation Thermal Standard Duty Fan Clutch

The Four Seasons 36994 is a reverse rotation thermal standard duty engine cooling fan clutch designed as a direct OEM replacement. As part of the SMP Temperature Control Division, Four Seasons engineers each fan clutch to meet or exceed original equipment specifications, ensuring reliable engine cooling performance you can count on.

This thermally activated fan clutch engages the cooling fan automatically when engine temperatures rise, and disengages at lower temperatures to reduce parasitic drag and improve fuel efficiency. The reverse rotation design is engineered specifically for applications requiring counter-clockwise fan operation.

Key Features:

• Reverse rotation design for correct counter-clockwise fan operation
• Thermal actuation — automatically engages and disengages based on engine temperature
• Standard duty construction suitable for normal-duty engine cooling demands
• Tested, validated, and inspected to meet or exceed OEM standards
• Direct-fit replacement for straightforward installation
• Cross-references: Hayden 2619

Four Seasons fan clutches are backed by decades of thermal management expertise and are manufactured to deliver consistent, dependable cooling system performance across a wide range of applications.
