How to Fill Windshield Wiper Fluid

If your Ram, Jeep, Dodge, Chrysler vehicle’s windshield fluid dash light is on—or if there’s not enough fluid jetting onto your windshield to clean it properly—you need to know how to refill windshield wiper fluid. Fortunately, it’s a simple process that should take just a few minutes! In the guide below, we’ll go over where to put windshield wiper fluid, how to use windshield wiper fluid to maximize visibility on the road in San Luis Obispo, and more.

What is Windshield Wiper Fluid?

Windshield wiper fluid is a cleaning fluid specifically formulated to clean car windshield glass. It’s typically composed of ethanol or methanol, which takes care of the cleaning, and a small amount of ethylene glycol (an alcohol used in automotive antifreeze) to prevent freezing at temperatures as low as -20 degrees.

If you’ve ever purchased wiper fluid, you may have wondered why there are so many different types. Does it matter what windshield wiper fluid you use? If you live in an area where the weather fluctuates dramatically between seasons, like Fresno, it’s a good idea to purchase special summer, winter, and all-season formulations. These wiper fluids come with additives like antifreeze or rain repellant designed to handle changing temperatures and conditions.

How to Use Windshield Wiper Fluid

Most vehicles have a button on the windshield wiper lever that releases wiper fluid. Anytime you notice streaks or buildup on your windshield, press it—and windshield wiper fluid will jet out from the nozzles on your windshield. The wiper blades will swipe automatically, cleaning the glass.

For proper visibility, your windshield must be clean both inside and out. However, we don’t recommend using windshield wiper fluid to clean the inside of your windshield. Regular glass cleaner and rubbing alcohol should work just fine!

Where to Put Windshield Wiper Fluid

Refilling the wiper fluid when it runs out may be the most important part of learning how to use windshield wiper fluid properly! Your vehicle will flash a dashboard warning when wiper fluid is low. If you’re wondering how to refill windshield wiper fluid, you can follow these steps as soon as you see the dash light:

. 

1. Find where to put windshield wiper fluid in your vehicle. The front/rear washer fluid reservoir is a translucent container with a windshield/water symbol, usually located near the engine.
2. Remove the reservoir cap to assess the fluid levels.
3. Carefully pour fluid into the reservoir, making sure not to go past the fill line marked on the container. A funnel may make it easier to get the fluid into the reservoir without splashing.
4. Pop the reservoir cap back into place.
