Four Seasons 5034N New Thermal Fan Clutch

The Four Seasons 5034N is a new (not remanufactured) thermal fan clutch designed as a direct OE replacement for vehicles equipped with an engine-driven cooling fan. As a critical component of the engine cooling system, the thermal fan clutch modulates fan speed based on engine temperature — disengaging at lower temperatures to reduce parasitic drag and fuel consumption, and engaging fully under high-heat conditions to maximize airflow through the radiator.

Key Features:

• New construction — not remanufactured; built to OE fit, form, and function
• Thermostatic bimetal spring responds to underhood temperatures for precise fan speed control
• Helps prevent engine overheating by ensuring proper airflow when needed most
• Reduces unnecessary load on the engine when the cooling fan is not required
• Precision-engineered to meet or exceed original equipment specifications
• Tested, validated, and inspected before leaving the factory

Four Seasons is a flagship brand of Standard Motor Products (SMP) and the largest aftermarket automotive temperature control parts supplier in the industry. Every Four Seasons thermal fan clutch undergoes rigorous quality control to ensure reliable, long-lasting performance as a direct replacement for the original cooling fan clutch.
