How to unfreeze windshield wiper fluid is a must-learn procedure in order to keep your car safe to drive while keeping your visibility good. However, it happens frequently during the colder months when the wiper fluid freezes, rendering it useless.
We’ll provide you with the knowledge you need in this step-by-step guide to defrost windshield washer fluid and keep your windshield clean over the winter.
How Do You Unfreeze Windshield Wiper Fluid?
To unfreeze windshield wiper fluid, you need to check the system first and check the reservoir for damage, heat up some water, open the bonnet and pour hot water, suck out the old fluid, and finally finish the process by pouring new fluid.
1. Check the System
It’s crucial to make sure the system is functioning properly before making an effort to defrost the windshield washer fluid. Turn on the wipers and attempt to utilize the fluid as soon as possible. The fluid is probably frozen if nothing leaks out. A blown fuse or a damaged motor may be to blame for the wipers not functioning at all.
For assistance in troubleshooting these problems, go to the owner’s handbook or speak with a professional. The fluid may be frozen if the wipers are functioning normally but the fluid is not dispensing. Avoid trying to push the system in this situation by repeatedly pressing the wiper fluid button as this might harm the system.
In colder climates, it’s crucial to keep in mind that using plain water instead of windshield wiper fluid might also result in freezing. Using specialized wiper fluid is better because it won’t freeze as often, as windshield washer fluid contains chemicals that reduce its freezing point.
It is vital to check the system since attempting to defrost the fluid without first making sure that it is functioning properly might cause more harm to the system. Adding hot water, for instance, can cause the reservoir to shatter if the fluid is frozen yet the system is leaking.
2. Check the Reservoir for Damage
The fluid reservoir should next be inspected for any damage once the windshield wiper system has been confirmed to be functioning properly. The reservoir, which typically houses the windshield wiper fluid under the hood of the automobile, is where it is placed. The reservoir should first be carefully inspected for any obvious fractures or corrosion.
Replace the reservoir as soon as you can if you discover any damage. Operating the system with a broken reservoir might result in fluid leaks, which further harm the car. It’s also crucial to make sure the reservoir is safely fastened to the vehicle. It can leak or harm the system if it is loose or removed. It is advised to take the vehicle to a technician or dealership for a complete check if you discover any obvious damage to the reservoir or if it is loose.
To guarantee that the system is operating properly, they can offer advice on the repairs or replacements that are required. The reservoir’s fluid level is another item to check. If the level is low, there may be a leak or the fluid may have run out. In this instance, topping out the reservoir with the windshield washer fluid is important before making an effort to defrost it.
3. Heat up Some Water
In order to guarantee that the fluid thaws fast, hot water should be used rather than cold or lukewarm water. From the faucet, pour hot water into a big pitcher. The water should be warm but not boiling. The plastic reservoir and other parts of the windshield wiper system may become damaged by boiling water.
It’s best to cover the pitcher with a lid or wrap it in a towel to guarantee that the water stays hot for a longer period of time. This will aid in maintaining the heat and stop the water from rapidly cooling. It makes sense to monitor the weather outdoors while the water is heating. It might be advisable to postpone trying to defrost the fluid until the weather improves if it’s too cold outside or the temperature is predicted to dip any lower.
This is so that the fluid won’t immediately freeze again and render the procedure of unfreezing worthless. It’s also crucial to refrain from defrosting the fluid with other heating techniques, including a hairdryer or heat gun. These techniques may harm the windshield wiper mechanism or perhaps provide a fire risk.
4. Open the Bonnet and Pour Hot Water
It is essential to guarantee that the hot water can reach the frozen fluid within the reservoir and thaw it out by opening the car’s bonnet and pouring hot water into the windshield wiper fluid reservoir. Find the hood release lever inside the car, which is often found under the dashboard or steering wheel, and pull it to lift the bonnet.
Go to the front of the car and pull the lever to release the hood latch after. Most automobiles have a clasp in the middle of the hood that must be opened in order to raise the hood. Open the hood and look for the reservoir holding the windshield washer fluid.
Typically, it comes in a transparent plastic bottle with a cover on top and is marked with the symbol for a windshield wiper. The hot water should be cautiously poured into the reservoir after removing the top. Avoid spilling the hot water to avoid burns or damage to the car’s components.
The reservoir must be filled to the recommended level listed in the owner’s handbook of the vehicle. Leaks or damage to the windshield wiper system may result from overfilling the reservoir. Replacing the reservoir cap and closing the hood is required once the hot water has been poured. It is best to wait a short while so that the hot water may defrost the frozen wiper fluid in the reservoir.
5. Suck Out the Old Fluid
You must drain the system’s old, frozen fluid after adding hot water to the reservoir for the windshield wiper fluid. This is required to avoid having any leftover ice or debris block the windshield wiper mechanism and impair its functionality. You can use a fluid removal instrument, such as a turkey baster or a fluid pump, to get rid of the old fluid.
Sucking out the old, frozen fluid requires inserting the instrument into the reservoir. Make sure you dispose of the old fluid appropriately and in accordance with any applicable municipal hazardous waste disposal laws. Use a fresh cloth or gentle sponge to remove the old fluid from the reservoir if you don’t have a fluid removal tool.
In addition, wring out the sponge or towel to get rid of as much liquid as you can. Before adding fresh fluid, it is crucial to completely drain the old fluid from the system since any ice or debris left behind might cause the new fluid to freeze and clog the system.
After removing the old fluid, you may clean the reservoir and the parts of the windshield wiper system using a solution of rubbing alcohol and water. By doing so, you can make sure the system is operating correctly and assist in clearing it of any dirt or residue.
6. Pour New Fluid
It’s time to replace the old, frozen windshield washer fluid in the windshield wiper system with fresh, unfrozen fluid. By doing this, you can be certain that the system is prepared to safely clean your windshield and keep you safe while you’re driving in bad weather. The correct kind of windshield washer fluid for your car must first be selected.
There are several alternatives available at most auto supply stores, including winter formulas that are made to withstand freezing in colder climates. To avoid future freezing, it’s crucial to select a fluid that is rated for the lowest anticipated temperature in your location. Next, find the reservoir for the windshield wiper fluid by lifting the hood of your car.
Remove the reservoir’s top, then pour the fresh, non-frozen liquids into it using a funnel. When you can see the fluid level directly below the fill neck, fill the windshield washer reservoir to the “full” line. Avoid overfilling the reservoir because doing so might result in fluid leakage and possible engine component damage.
As the fluid may be corrosive and damage other components if left on for too long, it’s also crucial to prevent pouring it on them. Replace the reservoir’s cap after adding fresh fluid, then turn the engine on. To make sure the windshield wiper system is operating correctly and that the fresh fluid is cleaning your windshield efficiently, test it out.
7. Finish the Process
The last stage is to make sure everything is in working order and that your car is prepared for safe driving in all weather. Check the windshield wiper system’s functionality first by testing it at various speeds and angles. It’s critical to fix any problems or discrepancies before starting out on the road.
Next, confirm that the reservoir for the windshield wiper fluid is correctly filled with fresh, unfrozen fluid and tightly closed. You can make sure you have adequate fluid by doing this to make your windshield stay clear and stop any more freezing problems.
Finally, check the engine block and other fluid reservoirs beneath your hood one last time to make sure everything is in order and operating as it should. You can stop any possible issues from occurring while driving if you do this.
