Windshield wiper fluid, also known as windshield washer fluid, helps you clean your windshield on command from the driver’s seat. Washer fluid contains water, ammonia to improve cleaning capacity, and alcohol to avoid streaks and frost formation. When mud or other substances cloud up your view forward, you may need to use your fluid and wipers to help wash the glass. Let’s cover all you’ll need to know about a Toyota’s windshield wipers and fluid.
How Do I Check My Wiper Fluid on my Toyota?
Windshield washer fluid isn’t normally something you check on a car, in the same sense as checking oil for when to replace it. However, it’s normal to check the volume in the reservoir and top it off to full. Here is the procedure to check and refill the wiper fluid in your Toyota:
- Leave the vehicle parked. Turn the engine off and disengage the parking brakes.
- Pull the release lever situated beneath the left side of the dashboard to open the hood.
- Proceed to the front of the car and depress the safety lever beneath the hood to open it.
- Look for the reservoir. You should see a windshield wiper symbol on the top of the cap.
- Remove the cover and put it somewhere secure if it isn’t looped into place.
- Place a clean funnel into the windshield washer fluid container.
- Fill to the line marked “Full” with windshield washer fluid. If there isn’t a mark, fill to about two inches below the cap.
- Squeeze the cap closed again.
- Start the automobile and test the windshield wipers by pressing the wiper stalk.
The windshield washer fluid may take a few seconds to spray on the glass. If there is no fluid spraying on the windshield, you may have a damaged fluid line, a malfunctioning windshield washer fluid pump, or a blown fuse. We recommend visiting a service center in Prosper to get these problems diagnosed and fixed before they become a bigger pain.
Why Checking Wiper Fluid Is Important
Windshield wiper fluid is handy for more than cleaning the glass. It’s a system that lets you regain visibility quickly, even while driving at higher speeds, so the fluid needs to work with the blades and rinse everything off as soon as possible. This is why windshield washer fluids with lubricants and other helpful additions work better than plain water.
There may be markings that show what volume is low, moderate, or full. If not, most reservoirs are clear and hold up to a gallon of fluid, so it’s rather obvious when they’re low or empty. If you let the wiper fluid in your Toyota go completely empty, not only will it not be available to help wash the windshield, but the plastic and other materials can overheat and degrade. Then, even when you do refill, it might leak out over time or fail to spray out.
When you can’t get a mess off your windshield, it can be stressful and may even force you to pull over. If you repeatedly have to refill your wiper fluid, it could be because of a leak, so we recommend contacting us to set up a service appointment and diagnose the exact cause.
Can I Just Use Water for my Toyota’s Windshield Wiper Fluid?
Designated windshield wiper fluid solutions are made to sit in the reservoir and do their job effectively. By comparison, you can use water to partially refill the reservoir, but it’s not recommended in the long run. It isn’t suited to remain in the reservoir as long and doesn’t have some of the beneficial features for cleaning. Regularly using water instead of windshield wiper fluid can result in issues like:
- Higher chance of windshield frost formation.
- Freezing and damage to washer components in cold weather.
- Bacteria and fungi growth.
- Premature wiper blade wear.
- Washer pump failure.
How to Keep Toyota Windshield Wiper Wash System in Top Shape
Apart from having enough windshield washer fluid, the nozzle and other components have to be working effectively. Let’s look at a few tips to keep your Toyota or other vehicle’s wiper washing system in top condition.
- Don’t use the washers if the fluid is low or empty to avoid stressing the system.
- Use proper windshield washing fluid instead of water to protect your system’s parts.
- Refill in between the season changes to prepare for them. Some fluids are designed for winter, others for summer.
- Don’t spill washer fluid on a hot engine. The alcohol can ignite, so try to refill when the engine is cold.
When Should the Fluid Be Replaced?
Apart from refilling when the fluid is low, there are no hard and fast rules about when to replace it. Still, one effective plan for the average car is to refill every six months. Many tasks available at our automotive service center can include us checking your reservoir and topping it up if necessary.
Keep in mind that you don’t always have to use wiper fluid to clean up your windshield. If you can see reasonably well and have the opportunity to wash or squeegee your car, that will work even better. Consider wiper fluid the quick option worth saving for when you need it.
When Should Toyota Wiper Blades Be Replaced?
Luckily enough, the average time to replace rubber windshield wiper blades is also once or twice a year. The common signs you need to replace your Toyota’s wiper blades are squeaking wipers, cracked or chipped rubber, or the wipers simply not cleaning like they used to.
