1. Open the engine cover and enter the cab to watch: remove the screws that fix the engine and the water tank frame, then remove the plastic plate above the fan, see the position of the blower clearly, and remove the fixing screws.
2. Remove the old fan with a wrench or sleeve, and then install the new fan: pay attention to the positive and negative sequence when installing, so as not to affect the heat dissipation effect and cause danger.
