The electric engine fan that's mounted in your Subaru isn't going to perform efficiently in the absence of a high-quality Subaru fan motor controlling it. The fan is developed to keep the engine temp at the right stage, but the fan won't be effective in doing so in the absence of the fan motor, the device that controls the fan.
While your Subaru powerplant functions, it produces too much heat energy because of the excessive activity of numerous engine devices at work - the temperature of the engine might get to an extremely high level and overheating might happen if this is not competently managed. The electric radiator fan switches on and off to regulate the engine temp, and it's the fan motor that works behind the fan to ensure that its performance is efficient. Fan motors are electricity-operated components that determine the timing when the fan should engage and when it shouldn't, based on the temperature in the powerplant of your ride. The mentioned components can be considered as the brain driving the cooling fan, and each ought to be maintained in top shape for the radiator fan to execute its task with ease in all given circumstances and for the motor's temp to be at the proper degree. Otherwise, if the fan motor in your Subaru gets defective, the cooling fan would definitely give up while at work.
