How to Drain Windshield Washer Fluid

8 Reasons Why You Should Drain Windshield Wiper Fluid

1. The most common reason for draining your windshield wiper fluid is to refill the reservoir with a preferred fluid.

2. If your fluid appears cloudy or discolored, or if it has a bad smell instead of the usual sugary scent, then it’s probably time to drain and replace your fluid.

3. A dirty reservoir can be another cause for concern. A dirty reservoir may restrict the fluid flowing through the wiper blades, causing them to streak or not clean properly. First, drain your reservoir, then refill it using one of the steps listed below for proper cleanup.

4. When changing winter wiper blades, you should change all external components of the wiper assembly, including the windshield washer fluid.

5. If you leak your windshield washer pump, it could be corroding other parts of the assembly as well as eating away at the sheet metal and rubber components of your vehicle’s underbody seal around the wheels and doors. Replacing these components early can help avoid costly future repairs since these areas are difficult and expensive to repair.

6. If it appears that your fluid is not draining properly, you may need to remove debris from your reservoir’s screen.     

7. If you notice that the pump motor seems to be making noise or overheating more than usual, try replacing the fluid in the reservoir and cleaning out the hose assembly for proper drainage.

8. If you do not know when your windshield washer fluid was last replaced, it is probably time to drain and replace the reservoir with fresh fluid.

Step by Step Guide: How to Drain Windshield Washer Fluid

Step 1: Open the Hood

The first step to draining windshield washer fluid is to open the hood of your car. Find the latch or handle that releases the hood and pull upwards, then set it aside.

Open the Hood

Step 2: Find the Washer Fluid Reservoir

Once you have opened your hood, locate your windshield washer fluid reservoir. Your car’s owner’s manual may have a diagram of the location of the washer fluid reservoir, or it may be located underneath your hood. If you cannot find it right away, check around for anything that looks like it could contain fluid.

Step 3: Locate the Washer Fluid Reservoir Cap

Once you have located your windshield washer fluid reservoir, look inside and locate the cap or lid of the tank. The reservoir cap will be attached to a tube that feeds directly into your car’s windshield washer fluid system.

Step 4: Unscrew Washer Fluid Cap

Now look for a silver screw on top of where the washer fluid tank used to be. This screw is connected to a tube that leads from the tank into the engine compartment, where it connects to your car’s washer fluid system. The valve on top of this tube is what allows you to control the flow of windshield washer fluid from your reservoir to your windshield washers. Unscrew this part using an adjustable wrench so you can get to the tank underneath it.

Step 5: Remove Fluid Reservoir

After you have loosened the washer fluid reservoir cap, there should be an opening where you can pour out or siphon off any remaining windshield washer fluid in your reservoir. If you wish to save this fluid for later use, be sure not to spill any on the floor of your car.

Step 6: Drain The Reservoir and Reconnect the Hose

Once you have completely drained the contents of your reservoir, it is time to reconnect the cap and reattach the tube leading from your reservoir into your car’s washer fluid system. If there was previously a gasket sealing the tank in place, replace that.

Step 7: Refill Washer Fluid Reservoir

Once you have reconnected the hose to your reservoir, you can begin refilling it with windshield washer fluid. The manufacturer recommends filling the tank with a 50/50 mixture of water and washer fluid concentrate for most cars. If you use prepackaged windshield washer fluid, use the same proportions listed on the label for best results.

Filling the Tank

Step 8: Test the System

After you have refilled your reservoir, it is time to test the washer fluid system to make sure everything has been reconnected properly. Start by turning on your windshield wipers and placing them in the middle of your windshield. Next, turn your car on and turn on the windshield wipers to their fastest setting. If your windshield wipers perform correctly without streaks or spots, then your system is functioning properly.

Step 9: Close Up Hood and Clean Up

Once you have refilled your reservoir and tested everything to make sure it is working again, close the hood of your car. Then wipe up any excess fluid that may have spilled on the floor of your car with a clean rag.

Step 10: Dispose of the Drained Washer Fluid

Now that you have drained the washer fluid from your windshield washer fluid tank, you can properly dispose of it by taking it to your local auto parts store or automotive waste disposal facility. Most auto parts stores will accept old windshield washer fluid for recycling at no cost, so bring yours in when you are able.

Note: There are several different techniques for draining windshield washer fluid. However, the process of draining your car’s washer fluid is relatively straightforward. All you need to do is locate your reservoir and follow the simple steps listed above. If you have any problems with your system or if anything seems out of place, make sure to take your car to a mechanic for servicing before attempting to drive it.

Some Tips and Suggestions

Here are some tips and suggestions on how to drain windshield washer fluid.

1. Always be careful when working with windshield washer fluid, as it can be very dangerous.

2. Acetone and similar chemicals are extremely flammable and should only be used outdoors in a well-ventilated area away from ignition sources such as open flames or sparks. Do not use acetone if you feel 100% comfortable using acetone to clean your windshield washer nozzles.

3. If your windshield washer nozzles are not clogged, you can use a rubber hose to siphon out the fluid. Just stick one end of the hose deep into the reservoir and place the other end in a container.

5. If you cannot find the windshield washer fluid reservoir, be sure to check your owner’s manual for instructions on where it is located.

7. Always dispose of windshield washer fluid safely and responsibly.

When to Drain Windshield Washer Fluid?

Windshield washer fluid is meant to be used and replaced, not saved for later use. There are two good reasons for this. First, the solution is corrosive and will eat away at various parts of your car’s windshield washer system over time. Second, fluids like windshield washer fluid only last about a month before oxidizing and becoming less effective.

Your windshield washer fluid reservoir is usually located inside your car’s engine compartment on the driver’s side of the vehicle. First, open up the reservoir cap to check how much fluid is in there. If it’s low, you can top it off with a fresh supply of windshield washer fluid. If your windshield washer fluid reservoir is empty, it’s possible to top off what little fluid you have in the tank with a new supply of cleaner, or you can drain the whole thing and replace it with new fluid.

How Can I Prevent My Car From Getting Drenched in Windshield Washer Fluid?

When it’s cold outside, there is a good chance that you will get drenched in windshield washer fluid when trying to clean your car. If you don’t want to get drenched, all you have to do is turn your windshield wipers on.

This will cause the washer fluid in the reservoir to be used up more quickly than usual. If you live in an area where it gets cold during the winter months, you should be prepared to get drenched in windshield washer fluid when the weather drops below freezing.

Conclusion

It is important to know how to drain windshield washer fluid to prevent leaks and overflow. Follow these steps mentioned in this blog post on how to do this task. There are many dangers associated with driving without sufficient water in your wipers, so make sure you have an emergency kit of sorts that includes a container for holding used wiper fluid as well as some paper towels or rags for cleaning up any spilled fluids before they drip onto anything else inside your car.
