Cooling Fan for GY6 50cc and 139QMB Engines
This cooling fan is built for GY6 50cc and 139QMB engines. Compared with a standard fan, it moves more air, which helps keep engine temperatures in check. It is one of the simpler GY6 50cc scooter parts to swap yourself at home. Its light weight allows it to sit exactly where the original fan does, so it suits riders who want a boost in performance.
Airflow and Efficiency
Relative to stock units, this fan uses an upgraded airflow design. That makes it a good match for demanding use, especially off-road riding and racing. Because it is lightweight, it adds no unnecessary bulk to the scooter, which helps performance stay where it should be.
Direct Replacement Fit
This fan is meant as a drop-in replacement for QMB139 and GY6 engines. The dimensions and bolt spacing match the original part, so installation is straightforward. If your engine has been running hot, swapping in this fan is a practical step toward keeping it running smoothly.
