Product Details

Four Seasons Fan Clutch 36950 is engineered for Jeep cooling systems that rely on a thermal fan clutch to regulate airflow through the radiator. Its reverse-rotation design, 4-bolt flange mounting, and standard-duty thermal operation make it a practical replacement for select Jeep Wrangler, Cherokee, Comanche, Wagoneer, CJ7, and CJ5 models.

Installation Notes and Tips

Verify reverse-rotation fan clutch requirements before installation. Confirm the fan bolt circle, mount diameter, pilot depth, and overall height match the original unit on your Jeep application. Mounting hardware is not included, so reuse or source the correct hardware separately as needed. Always inspect the fan, water pump area, and surrounding cooling components during replacement.
