Product Details
The Four Seasons 36749 is engineered as a severe-duty engine cooling fan clutch for vehicles that rely on mechanical fan engagement to manage operating temperature. Its thermal operation responds to heat demand, helping the fan engage when cooling load increases and reduce drag when full airflow is not needed. The aluminum housing, 1.88-inch mount diameter, 1.18-inch pilot diameter, and 0.67-inch pilot depth support a precise fit where the application matches the published dimensions. If you are replacing a worn fan clutch on a Ford, Chevrolet, or Dodge truck cooling system, this part number 36749 provides a direct-fit style solution for the correct mounting and rotation setup.
This part cross-references CSF 2834 for the same application.
Common Problems This Part Can Address
- Engine temperature rising at idle or in slow traffic
- Fan engagement that feels inconsistent or delayed
- Excessive fan noise from a worn mechanical clutch
- Reduced cooling performance under towing or heavy-load use
- Cooling system strain caused by a failing truck fan drive
Installation Notes and Tips
Verify the fan bolt circle, mount diameter, pilot dimensions, and rotation before installation to confirm the replacement matches the original cooling fan clutch. Mounting hardware is not included, so reuse or source the correct hardware separately if needed. Because this is a severe-duty thermal fan clutch, proper alignment and secure mounting are important for stable fan operation and cooling performance.
Quality Assurance
Four Seasons lists this fan clutch as new, performance rated, and meeting or exceeding OEM requirements. The 36749 is built for severe-duty service and is intended for direct replacement use in applications that call for this specific thermal fan clutch design.
