These washer nozzle pair mount on the bonnet and sprays washer fluid onto the windshield. When these nozzles get old they can clog or spray uneven. That makes it hard to clean the glass, and can make visibility bad. Replacing the nozzle brings back a clean and correct spray pattern.

The purpose of the Washer Jet is to spray washer fluid evenly onto the windshield, helping to remove dirt, debris, and grime for clear visibility while driving. It works as part of the vehicle’s windshield washer system, directing the fluid from the washer reservoir through the nozzles onto the glass. This ensures safe driving conditions by keeping the windshield clean, especially during rain, dust, or muddy road conditions.

This is not a universal nozzle .It is a direct swap for the worn or broken nozzle on Toyota J90 models
