Hayden Automotive 2587 Thermal Fan Clutch for 5-6 Inch Import Applications

The Hayden Automotive 2587 is a thermal standard duty fan clutch designed specifically for 5-inch and 6-inch import vehicle applications. This precision-engineered cooling system component automatically regulates engine fan speed based on underhood temperature, providing optimal cooling performance while maximizing fuel efficiency and reducing noise.

Key Features:

• Thermal standard duty design with bi-metal thermal spring temperature sensing
• Type A clutch configuration for 5-inch and 6-inch import fans
• Fan bolt circle diameter: 5.47 inches (138.9mm)
• Distance from clutch to mounting flange: 2.38 inches
• Standard rotation, non-electronic operation
• Smooth steel faceplate with thermal spring assembly on front side
• Engages fan at 70-90% shaft speed when cooling is needed
• Disengages to 25-35% shaft speed when engine is cool for improved fuel economy

This replacement fan clutch is manufactured to meet strict OE specifications for fit, performance, and durability. The thermal spring automatically senses underhood temperature and engages the fan clutch accordingly—keeping the engine cool when needed while reducing parasitic power loss and fan noise during normal operation.
