Subaru Legacy BN/BS (2015-2019) Owners Manual: Cleaning ventilator grille

1) Front ventilator inlet grille

Always keep the front ventilator inlet grille free of snow, leaves, or other obstructions to ensure efficient heating and defrosting.

Since the condenser is located in front of the radiator, this area should be kept clean because cooling performance is impaired by any accumulation of insects and leaves on the condenser.
