If you have a leaking windshield wiper fluid, it’s important to take care of it as soon as possible. Not only is the fluid irritating and potentially dangerous if it gets in your eyes, but it can also damage your car. In this post, we’ll tell you what to do if your windshield wiper fluid starts leaking and how to prevent it from happening in the first place. Stay safe on the road!
Symptoms for leaking windshield wiper fluid
If you notice any of the following warning signs, it might be time to replace your windshield washer reservoir:
Fluid is leaking from below your car
If you notice fluid leaking from below your car, it could be windshield wiper fluid. Symptoms of this include streaking or smearing on your windshield, as well as a potential decrease in the level of fluid in your reservoir.
If you think this is the problem, it’s important to act quickly. Windshield wiper fluid is essential for keeping your windshield clean and clear, and if it runs out completely, you could be at risk for an accident. To top it off, a leaking reservoir can also cause damage to your car’s paint. If you notice any of these symptoms, be sure to take your car to a mechanic right away so they can diagnose and fix the problem.
Washer fluid is not spraying onto the windscreen
If your windshield wiper fluid isn’t spraying onto the windscreen, it could be because the reservoir is leaking. This is typically caused by a cracked or damaged reservoir, which can be caused by age, heat, or impact.
First, check the pump to see if it’s working. If the pump is working but the fluid isn’t coming out, then the nozzle is probably blocked. Try cleaning it with a paperclip or similar object. If that doesn’t work, you may need to replace the nozzle.

Washer fluid is often low or empty
If you find that you are constantly having to refill your windshield wiper fluid, there may be a leak in the reservoir. Inspect the reservoir for any cracks or holes. If you find a crack, you will need to replace the reservoir. If there is a hole, you can try to seal it with epoxy or another type of sealant. If the leak is severe, you may need to replace the entire reservoir.
Cracks in the tank
If you notice cracks in the windshield wiper fluid reservoir, it’s important to replace it as soon as possible. Cracks can cause leaking, which can lead to all of the problems we’ve already mentioned. In addition, cracks can also lead to dirt and other contaminants getting into the reservoir, which can clog the pump or damage other parts of the system.
To prevent leaking windshield wiper fluid, it’s important to check your reservoir regularly for any signs of damage. If you notice a crack or hole, be sure to take your car to a mechanic right away so they can fix the problem. You should also avoid overfilling the reservoir, as this can put stress on the tank and cause it to crack. Keep your windshield wiper fluid at the proper level, and be sure to check it regularly to keep your windshield clean and clear.
How to Replace the Windshield wiper fluid
Replacing the windshield wiper reservoir is a pretty easy task that you can do at home. You’ll need a few tools and supplies, but otherwise, it’s a fairly straightforward process.
Step1: Prepare the car
First, you’ll need to prepare your car for the repair. Park the car on a level surface and turn off the engine. Then, open the hood and locate the windshield wiper fluid reservoir. It’s usually located near the front of the car, so it should be easy to find.
Step 2: Disconnect the negative battery cable
Next, you’ll need to disconnect the negative battery cable. This will prevent any electrical shocks while you’re working on the car. To do this, simply loosen the nut on the negative battery terminal and pull the cable off.

Step 3: Remove the old reservoir
Once you’ve disconnected the negative battery cable, you can remove the old reservoir. There are usually two bolts holding the reservoir in place. Remove these bolts and carefully lift the reservoir out of the car.
Step 4: Install the new reservoir
To install the new reservoir, simply reverse the process. Place the new reservoir in the car and bolt it into place. Then, reconnect the negative battery cable.
Step 5: Fill the reservoir with fluid
Once the new reservoir is in place, you’ll need to fill it with windshield wiper fluid. Pour the fluid into the reservoir until it’s full. Then, close the hood and test the wipers to make sure they’re working properly.
