How to Check The Windshield Washer Fluid Level
Most cars have apparatus that sprays a soapy liquid on the windshield when you push a button inside the car. This windshield washer fluid is stored in a reservoir or container under the hood of your car. Certainly it’s not as critical as the oil, but running out washer fluid can make it difficult to see through a dirty windshield.
Find the windshield washer fluid reservoir. It is typically a clear or white plastic container holding a pint to a quart of colored liquid. the reservoir may look like a milk jug or a jar.
Visually check the fluid level. Some reservoirs have a mark on the side indicating the full level. If there’s no mark, an inch or two below the top of the reservoir is the full level. Never fill reservoir to the top because the liquid may expand with weather change.
If the reservoir registers less than one half full (or one half empty, depending on your view of life), open the top of the reservoir, fill with windshield washer fluid, and replace the top. Some reservoir tops snap on and off; other are screwed on and off.
What should you fill the reservoir with? You can buy replacement windshield washer fluid at nearly any large store for a dollar or two a gallon. You can also make your own using water and a windshield washer concentrate such as 20/20, or you can use a drop or two of liquid dishwashing detergent.
