Windshield washer fluid leak

A windshield washer fluid leak occurs when the windshield washer reservoir cracks or becomes damaged, and the fluid inside begins to leak. On most cars, the windshield washer fluid reservoir is located at the rear of the engine compartment, near the base of the windshield. The tank is translucent to allow you to see if there is liquid inside or not.

Often older vehicles have the washer reservoir located near the exhaust systems, due to the intense heat, over time the reservoir will begin to crack and leak. This will cause fluid to leak from the washer reservoir until it is empty.

The windshield washer fluid reservoir contains windshield washer fluid, which is used to spray and clean the windshield. Windshield washer fluid is a bright blue or green fluid. It is often made up of methanol and some toxic alcohols (ethylene glycol), which is poisonous.


Symptoms of a windshield washer fluid leak

  • Fluid leaking from under your car

You’ll be able to tell if your windshield washer fluid is leaking if you notice light blue or light green fluid coming out from under your car, typically near one of the front tires. Or more often if the windshield washer fluid was recently topped up, but it stopped dripping on the windshield soon after.

The leak can be caused by heat from the exhaust system on older cars. However, the most common cause of a cracked reservoir is due to owners putting water into the system, rather than direct washer fluid. This is usually because washer fluid can be expensive. When temperatures drop too low, the water inside the unit will freeze. This causes the plastic to harden and crack once it thaws!


  • Windshield washer fluid does not spray on the windshield

When the system is connected and you can hear the pump running but not spraying washer fluid, this may be due to a ruptured reservoir. If the reservoir is damaged, all the fluid will drain.

This is common when only water is used in the windshield washer unit. The reservoir can develop rust, especially near the outlet port where the pump connects or draws fluid.

Unfortunately, if mold is the problem, it cannot be eliminated. This will require a mechanic to replace the entire windshield washer reservoir and often replace the fluid lines as well.

  • Windshield washer fluid is often low or empty

If your windshield washer fluid is leaking, you’ll get a puddle of water or blue or green fluids under your car. Leaking or damage to the reservoir will cause your windshield washer fluid level to often be low or empty. So if you regularly fill your washing machine’s tank but find that it becomes low or empty very quickly, you probably have a damaged tank that is leaking.

If your washer tank is empty and you turn on the washer pump, it may cause the pump to burn out. If you burn out the pump, it will have to be replaced.

Keeping your windshield washer fluid topped up is a lot more important than people think. Keeping fluids topped up can prevent your washer tank from cracking or getting damaged. A great way to prevent a windshield washer fluid leak is to get serviced.

How can I tell if my windshield washer pump is faulty?


Common signs include washer fluid not being sprayed evenly, fluid not being sprayed on the windshield, and the pump not activating when you activate the system.

Believe it or not, one of the easiest parts to maintain on every car, truck, or SUV is the windshield washer pump. Although many car owners experience problems with their windshield washer system at some point in their car ownership, proper maintenance, using only windshield washer fluid and replacing washer nozzles when they wear out can keep the washer pump healthy. running flawlessly practically forever. Sometimes it’s hard to do all of this, which can cause the windshield washer pump to wear out or fail altogether.

There are a few warning signs that may indicate that there is a problem with the windshield washer pump and that it should be repaired or replaced by a certified mechanic in your area. Here are some of these symptoms to look out for that will indicate a potential problem with your washing machine’s pump.

1. Windshield washer fluid does not spray evenly

When you pull back on the windshield washer control arm or activate the windshield washer fluid by pressing a button, the windshield washer fluid is supposed to be sprayed evenly on the windshield. If this does not occur, it is most likely due to one of two things:

  • A blockage within the lines or nozzles.
  • A washer pump that is not fully functional

Although the pump is generally an all or nothing system, there are times when the pressure or volume of flushing fluid it can deliver will begin to drop as the pump begins to wear. If you notice this symptom, it is recommended that you have a mechanic inspect the windshield washer pump and nozzles to verify what the problem is and repair it quickly.

2. No fluid is sprayed on the windshield

If you’re having this problem, again, it’s one of two things. The first and most common is that the windshield washer fluid reservoir is empty or that the pump is broken. There are a few times when the problem can be with the washer nozzles, but if this occurs, you will see washer fluid flowing behind or to the side of the nozzle. Car manufacturers recommend checking your windshield washer fluid once a week. A good rule of thumb is to open the hood and check the washer fluid at every gas fill. If you’re low on fluid, most gas stations sell a gallon of windshield washer fluid that can easily fill the reservoir.

3. Pump does not turn on when you activate the system

The windshield washer pump makes a distinctive sound when it activates windshield washer fluid to spray onto the windshield. If you press the button and hear nothing, and no fluid is sprayed on the windshield, this indicates that the pump is broken or not receiving electrical power. If this is the case, check the fuse that operates the washer pump to see if it has blown and replace it if necessary. However, if the fuse is not the problem, you will need to contact a local ASE certified mechanic to have the windshield washer pump replaced.

Windshield washer fluid: Can you add dish soap to it?


You may have heard some people recommend adding dishwashing fluid to the windshield washer reservoir.


It sounds logical at first. If dish soap can cut through grease, it surely can help clean the grime off your windshield. But there are negative effects to doing this.


It is easy to clean the windshield during a heavy downpour.


However, there are those sunny mornings when you get in your car and have to look through a glass smeared with bird droppings. They usually stick like glue and even several wipes of your wiper with the washer spraying continuously won’t remove them.


The safest way to clean your windshield is to use a special car shampoo when washing it.


Otherwise, use a cloth and plenty of water. Most contaminants, including bird droppings, need to be soaked in water or windshield washer fluid before they start to come off. The latter is even more effective.


Good windshield washer additives are available at most gas stations and in the auto accessories sections of supermarkets. They all contain some percentage of alcohol, so read the instructions on how much to mix with your tank water.


Remember that when you use the water jets, a certain amount of liquid eventually flows into the body of the car. Therefore, too strong washing solutions can scratch the paint.


A windshield washer reservoir containing any amount of household detergent should never be used.


These fluids are formulated to remove grease and oil from ceramic, stainless steel, and glass. Therefore, most of these are harmful to the wax and even the clear coat that protects the paint.
