Lasinpesujärjestelmän

Lasinpesujärjestelmä, or windshield washer system, is a common automotive feature designed to improve driver visibility by cleaning the front windshield. It typically consists of a reservoir to hold washer fluid, an electric pump to draw fluid from the reservoir and push it through hoses, and nozzles mounted on the hood or wiper arms that spray the fluid onto the windshield. When the driver activates the system, usually via a stalk on the steering column, the pump operates, delivering washer fluid to the glass. Many systems also include a wiper function that activates automatically or is manually controlled to sweep the fluid and any debris away.

The washer fluid itself is a mixture of water and specialized cleaning agents, often containing antifreeze to prevent freezing in cold weather. This ensures the system remains operational even in sub-zero temperatures. The cleaning agents help to break down dirt, grime, insects, and road salt, which can significantly obstruct the driver's view. Regular topping up of the washer fluid reservoir is essential for maintaining the system's functionality. Some vehicles also have a similar system for the rear windshield and headlights. The proper functioning of the lasinpesujärjestelmä is crucial for safe driving, especially in adverse weather conditions.
