Replace Windshield Washer Reservoir

Is Your Windshield Washer Reservoir Cracked or Leaking? Here's How to Replace It

A functioning windshield washer system is crucial for safe driving, especially in inclement weather. Road grime, salt, and insect splatter can quickly reduce visibility, and a quick spray of washer fluid can make all the difference. However, if your windshield washer reservoir is damaged, cracked, or leaking, your washer system won't work properly. This article provides a comprehensive guide on how to replace your windshield washer reservoir, ensuring you have a clear view of the road ahead.

Why Replace Your Windshield Washer Reservoir?

Several reasons might necessitate replacing your windshield washer reservoir. The most common include:

Cracks: Over time, the plastic material of the reservoir can become brittle and develop cracks due to age, exposure to extreme temperatures, or impact from road debris.
Leaks: Cracks, loose connections, or damaged seals can lead to washer fluid leaks, resulting in an empty reservoir and a non-functional washer system.
Damage from Accidents: A minor fender bender or collision can directly damage the reservoir.
Pump Failure (in some cases): Although less common, sometimes replacing the entire reservoir is easier than just replacing the pump, especially if the pump is integrated into the reservoir design.

Ignoring a damaged windshield washer reservoir can lead to:

Reduced visibility: Driving with a dirty windshield is dangerous and can impair your ability to see clearly.
Safety hazard: Poor visibility increases the risk of accidents.
Costly repairs: Leaving a leak unaddressed can potentially damage other components in the engine bay.
Legal issues: In some jurisdictions, it's illegal to drive with a non-functioning windshield washer system.

Tools and Materials You'll Need

Before you begin, gather the necessary tools and materials:

New Windshield Washer Reservoir: Purchase a reservoir specifically designed for your vehicle's make, model, and year. Check the fitment details carefully to avoid compatibility issues.
Basic Hand Tools:
- Socket set with various sizes
- Wrench set
- Screwdrivers (Phillips head and flat head)
- Pliers
Drain Pan: To catch any spilled washer fluid.
New Washer Fluid: To refill the reservoir after replacement. Choose a fluid appropriate for your climate.
Gloves: To protect your hands.
Safety Glasses: To protect your eyes from debris and fluid.
Penetrating Oil (Optional): For loosening stubborn bolts.
Shop Rags: For cleaning up spills.
Flashlight or Work Light: For better visibility.

Step-by-Step Guide to Replacing Your Windshield Washer Reservoir

Follow these steps carefully to replace your windshield washer reservoir. Remember to consult your vehicle's repair manual for specific instructions related to your model.

Safety First: Disconnect the negative terminal of your car battery to prevent any electrical shorts during the process. This is a critical safety precaution.
Locate the Windshield Washer Reservoir: The reservoir is typically located in the engine bay, often near the fender or firewall. Consult your owner's manual if you're unsure of its location.
Drain the Existing Washer Fluid: Before removing the reservoir, drain the remaining washer fluid into a drain pan. You can disconnect the washer fluid hose at the pump (if accessible) or use a siphon to remove the fluid. Be careful not to spill any fluid.
Disconnect the Washer Fluid Hoses: Carefully disconnect the washer fluid hoses from the reservoir and/or pump. Use pliers if necessary, but be gentle to avoid damaging the hoses. Take note of the hose routing for reassembly. It's helpful to take a picture beforehand.
Disconnect the Electrical Connector (if applicable): If your washer pump has an electrical connector, disconnect it. Gently squeeze the connector's release tab before pulling it apart.
Remove the Reservoir: The reservoir is usually held in place by bolts, screws, or clips. Remove these fasteners to release the reservoir. Some reservoirs may require you to remove other components, such as the air intake or fender liner, to access them. Pay close attention to how the reservoir is mounted.
Transfer the Washer Pump (if necessary): If your new reservoir doesn't come with a pump, you'll need to transfer the pump from the old reservoir to the new one. Gently remove the pump from the old reservoir, being careful not to damage it. Install the pump into the new reservoir, ensuring it's securely in place. Some pumps have a rubber grommet seal; make sure this is correctly installed.
Install the New Reservoir: Position the new reservoir in the same location as the old one. Secure it with the bolts, screws, or clips you removed earlier. Ensure it's firmly attached.
Reconnect the Washer Fluid Hoses: Reconnect the washer fluid hoses to the reservoir and/or pump, following the routing you noted earlier. Ensure the hoses are securely attached to prevent leaks.
Reconnect the Electrical Connector (if applicable): Reconnect the electrical connector to the washer pump. Make sure it clicks into place.
Refill the Reservoir: Fill the new reservoir with fresh washer fluid.
Reconnect the Battery: Reconnect the negative terminal of your car battery.
Test the System: Start your engine and test the windshield washer system. Ensure the washer fluid sprays properly onto the windshield. Check for any leaks around the reservoir and hoses.
Clean Up: Dispose of the old reservoir and any spilled washer fluid properly.

Troubleshooting Tips

If you encounter any problems during the replacement process, consider these troubleshooting tips:

Hoses are difficult to disconnect: Use pliers to gently loosen the hoses. If they're stuck, try applying some penetrating oil.
Bolts are seized: Apply penetrating oil and let it soak for a few minutes before attempting to loosen the bolts.
New reservoir doesn't fit properly: Double-check that you purchased the correct reservoir for your vehicle's make, model, and year.
Washer fluid isn't spraying: Check the washer fluid level, hoses for kinks or blockages, and the pump's electrical connection. The pump itself may be faulty.
Leaking Reservoir: Ensure all connections are tight and the reservoir is properly seated. If the reservoir still leaks, it may be defective and need to be replaced again.

When to Seek Professional Help

While replacing a windshield washer reservoir is a relatively straightforward task, there are times when it's best to seek professional help from a qualified mechanic. Consider professional assistance if:

You're not comfortable working on your car.
You lack the necessary tools.
You encounter significant difficulties during the replacement process.
You suspect there may be other underlying issues with your vehicle's washer system.

Maintaining Your Windshield Washer System

To ensure your windshield washer system remains in good working order, follow these maintenance tips:

Use High-Quality Washer Fluid: Choose a washer fluid that's appropriate for your climate and contains additives to help clean your windshield effectively.
Check the Fluid Level Regularly: Keep the reservoir topped up with washer fluid.
Inspect the Hoses: Check the hoses for cracks, leaks, or damage. Replace them if necessary.
Clean the Washer Nozzles: Use a small needle or pin to clean any clogged washer nozzles.
Use a Winter Washer Fluid: During winter, use a washer fluid with antifreeze properties to prevent the fluid from freezing in the reservoir and hoses. This is crucial to prevent damage.

Finding the Right Replacement Windshield Washer Reservoir

There are several places where you can purchase a replacement windshield washer reservoir:

Auto Parts Stores: Local auto parts stores typically carry a wide selection of reservoirs for various vehicles.
Online Retailers: Online retailers offer a convenient way to shop for reservoirs, often with competitive prices. Make sure to check the seller's reviews before purchasing.
Dealerships: Your local car dealership can provide genuine OEM reservoirs that are specifically designed for your vehicle.
Junkyards: You may be able to find a used reservoir in good condition at a junkyard, but ensure to check the reservoir for leaks or cracks.

Conclusion

Replacing your windshield washer reservoir is a manageable DIY project that can save you money and ensure your safety on the road. By following these steps and taking the necessary precautions, you can restore your windshield washer system to proper working order and maintain clear visibility while driving.
