Although it’s often overlooked, the windshield wiper fluid is one of the most important liquids in your vehicle. Therefore, you should make sure you always have enough fluid in your car’s wiper fluid reservoir. Checking this is a quick and easy task, but the process may differ from one vehicle to another. Follow this detailed guide to properly check and refill the wiper fluid in your Lexus.
Why Is It Important to Regularly Check Your Windshield Wiper Fluid?

When you drive your Lexus or park it outside, many things can accumulate on your windshield, such as dirt, grime, mud, bug splatters, pollen, and bird droppings. These substances can make it difficult for you to see the road ahead, increasing your chances of getting into an accident. This not only jeopardizes you and your passengers’ safety, but it can also endanger the lives of the motorists and pedestrians around you.
If you have enough wiper fluid in your vehicle, you can easily get rid of the dirt, grime, and debris that gathers on your windshield, keeping it clean and clear. Besides improving your safety, a clean windshield also contributes to a more relaxing and pleasant driving experience. On the other hand, if you run out of wiper fluid, you run the risk of having a smeared or streaked windshield, which can make driving dangerous and stressful.
Another reason why you should check and top up your windshield wiper fluid on a regular basis is because it can help keep your windshield washer pump well-lubricated. When your wiper fluid reservoir is empty, the pump may dry up as well, making it more likely to leak, corrode, or stop working altogether. If you repeatedly turn on your windshield washer system without any fluid inside, it may completely destroy the pump, which is relatively expensive to replace.
When there isn’t enough fluid on the glass, the rubber blades of your wipers will be dragged across a dry surface. This not only results in streaks, but it can also permanently damage your windshield and wipers. Also, it’ll put additional strain on your windshield wiper motor, making it more likely to break down.
How Often Should You Check Your Wiper Fluid Level?
Your windshield wiper fluid is different from your engine oil in that it doesn’t become degraded over time, so you don’t need to replace it at a specific interval. However, you do have to refill your wiper fluid as it gets used. Its beneficial to top up the liquid before it runs out completely. You should check your wiper fluid level once every two months or every time you take your car to the service center for routine maintenance.
How to Check the Wiper Fluid Level in Your Lexus
Checking and topping up the windshield wiper fluid in your Lexus is an easy task that shouldn’t take more than a few minutes. Follow the steps below to get the job done right:
Open the Hood
The windshield washer fluid reservoir is located under the hood of your Lexus vehicle. As such, the first thing you need to do is to open the hood. To do this, pull the hood release lever, which is located under the dashboard to the left of the steering wheel. This unlocks the hood and pops it up a few inches. Then, slide your fingers under the hood and move the locking latch to open it fully. Use the prop rod to support the hood.
Find the Windshield Washer Fluid Reservoir
In most Lexus models, the windshield washer fluid reservoir is located on the left side of the engine bay. It’s usually white and translucent and has a cap with a wiper symbol similar to the one on your dashboard.
Check and Refill the Wiper Fluid
After you’ve located the reservoir, check to see if it has enough fluid in it. Ideally, the fluid level should be about two inches from the top of the cap. If it isn’t, go ahead and fill the reservoir to that level.
What Type of Wiper Fluid Should You Use?
When you’re refilling your windshield washer reservoir, it’s important to use the right type of fluid. The best wiper fluid for your Lexus depends on your location and personal preference. If the conditions in your area are relatively neutral, standard washer fluid should be sufficient. Also known as general-purpose or all-season fluid, it’s inexpensive and widely available in gas stations, convenience stores and supermarkets. However, if you routinely have to deal with sticky bugs and bird droppings, you can get a formula that’s specially designed for removing these stains. There’s also an anti-fog fluid that can help prevent mist formation.
Bear in mind that you should avoid using water as windshield wiper fluid. This is because water doesn’t have the chemicals that can wash away stubborn dirt and grime. Also, it can develop bacteria in extremely high temperatures, which can pose a health hazard for you and your family.
When Should You Replace Your Windshield Wipers?
Even if you always have enough fluid in your windshield washer reservoir, you may not be able to keep your windshield clean if your windshield wipers aren’t in good condition. Windshield wipers with nicked or torn blades may leave streaks and uncleared sections on your windshield because they allow water to pass through them. If one of your wipers is missing the rubber edge, it can even cause deep scratches on your windshield. Therefore, it’s essential that you regularly replace your windshield wipers, preferably once every six to 12 months or three to six windshield washer fill-ups.
