The process of removing the liquid used to clean a vehicle’s windscreen from its reservoir is a maintenance procedure. This task involves accessing the reservoir, typically located under the hood, and employing a method to evacuate the existing fluid. For example, one might disconnect a hose leading to the washer nozzles and use gravity or suction to empty the tank.
Regular execution of this task can prevent the buildup of sediment or the mixing of incompatible fluid types. It also allows for the replacement of the cleaning agent with one more suitable for prevailing weather conditions, such as a formulation with enhanced de-icing capabilities during winter. Historically, simple water was used, but modern formulations offer better cleaning and freeze protection.
