The engine fan wheel is located between the engine and the radiator. The part can be of different design:

The plastic fan wheel is more whimsical to the operating conditions. An excessively low or high temperature has a negative effect on it: in severe frost, the element can crack, burst and even break off. The metal fan wheel allows you to expand the operating temperature range, but still does not last forever. If, by all indications, the fan wheel has become unusable, the best option would be to pick up a new spare part and replace it.
