Detailed Description

The Gates FCM143 cooling fan control module is used in vehicles equipped with electric cooling fans that require precise speed management. By varying fan output instead of running the fan at full speed all the time, the module helps the cooling system respond more accurately to engine temperature demands. This makes it a practical replacement for select Lexus and Toyota platforms, including Lexus IS300, Lexus RX450h, Lexus NX200t, and Toyota Highlander applications.
