AISIN Cooling Fan Clutch | Manual 20R / 22R / 22RE (1984 4Runner / 1979, 1984-92 Pickup)

AISIN Cooling Fan Clutch

For verified manual-transmission Toyota applications: 1984 4Runner with 22R, 1979 Pickup with 20R, and 1984–1992 Pickup with 22R / 22RE.

Overview

AISIN is the OE fan-clutch manufacturer associated with these Toyota cooling-system applications. This standard-duty thermal fan clutch regulates engine-driven fan speed as cooling demand changes, helping provide airflow at low vehicle speed without keeping the fan fully engaged at all times.

Toyota used different AISIN fan-clutch configurations for automatic-transmission, turbocharged, later 4Runner, and 1993–1995 Pickup applications. This unit is limited to the verified manual-transmission fitment below.

Key Features

• OE-manufacturer replacement for verified Toyota R-series applications
• Manual-transmission fitment for the applications below
• Standard thermal design that responds to cooling demand
• Clockwise rotation for the factory-style mechanical cooling fan system
• Direct-fit construction with no universal adapter or wiring
• New replacement component — not remanufactured
