How To Replace Windshield Washer Pump

Replacing your windshield washer pump is a repair that many car owners can tackle themselves, saving time and money compared to a professional mechanic. This article provides a comprehensive guide to help you understand the process, choose the right replacement part, and successfully complete the job.

Why Replacing Your Windshield Washer Pump Matters

A functioning windshield washer system is crucial for safe driving. It allows you to clear debris, dirt, and grime from your windshield, ensuring optimal visibility in various weather conditions. A malfunctioning washer pump can significantly impair your ability to see clearly, especially during rain, snow, or when driving on dusty roads. Ignoring a broken washer pump can lead to dangerous driving conditions.

Furthermore, having a working washer system is often a requirement for vehicle inspections. Failing to address this issue could result in your vehicle failing inspection, preventing you from legally operating it on public roads.

Finally, replacing the windshield washer pump yourself is a relatively inexpensive repair. A new pump typically costs between $20 and $100, depending on the vehicle make and model. Labor costs at a mechanic can easily double or triple that amount, making a DIY replacement a financially smart choice.

How to Choose the Right Windshield Washer Pump

Selecting the correct replacement pump is essential for a successful repair. Here's what to consider:

1. Vehicle Make, Model, and Year

The most critical factor is compatibility. Washer pumps are vehicle-specific, so you need to find one designed for your exact make, model, and year. Using the wrong pump can lead to poor performance or even damage to your vehicle's electrical system.

You can typically find this information in your vehicle's owner's manual, on your vehicle registration, or by using an online parts lookup tool. Most auto parts stores have websites where you can enter your vehicle information to identify compatible parts.

2. OEM vs. Aftermarket

OEM (Original Equipment Manufacturer) pumps are made by the same manufacturer that supplied the original pump for your vehicle. They are typically the most reliable and best-performing option, but they can also be more expensive.

Aftermarket pumps are made by third-party manufacturers. They can be a more affordable alternative, but the quality can vary significantly. When choosing an aftermarket pump, look for reputable brands with positive customer reviews. Research the manufacturer's warranty and return policy.

3. Number of Outlets

Some vehicles have separate pumps for the front and rear windshields, or for the headlights. Check the original pump to determine the number of outlets it has. Ensure the replacement pump has the correct number of outlets to match your vehicle's system.

4. Voltage and Flow Rate

The voltage of the replacement pump must match your vehicle's electrical system (typically 12V). The flow rate, measured in gallons per minute (GPM) or liters per minute (LPM), indicates the pump's ability to deliver washer fluid. Choose a pump with a flow rate similar to the original for optimal performance.

5. Reviews and Ratings

Before purchasing a pump, read online reviews from other vehicle owners. Pay attention to comments about the pump's performance, durability, and ease of installation. A pump with consistently positive reviews is more likely to be a good choice.

Steps to Replace Your Windshield Washer Pump

Here's a step-by-step guide to replacing your windshield washer pump. Always consult your vehicle's service manual for specific instructions.

1. Gather Your Tools and Materials

• New windshield washer pump
• Socket set
• Screwdrivers (Phillips and flathead)
• Pliers
• Jack and jack stands (if needed)
• Drain pan
• Safety glasses
• Gloves
• Shop towels

2. Disconnect the Battery

Safety First! Disconnect the negative terminal of your vehicle's battery to prevent electrical shocks or damage during the repair.

3. Locate the Washer Fluid Reservoir

The washer fluid reservoir is typically located in the engine compartment, often near the fender or firewall. Consult your vehicle's owner's manual if you're unsure of its location.

4. Drain the Washer Fluid

Place a drain pan under the reservoir and disconnect the washer fluid hose from the pump. Allow the fluid to drain completely.

5. Access the Washer Pump

The location of the washer pump varies depending on the vehicle. In some cases, you can access it directly from the engine compartment. In other cases, you may need to remove the wheel and inner fender liner for access.

If you need to remove the wheel, use a jack and jack stands to safely lift and support the vehicle.

6. Disconnect the Electrical Connector

Carefully disconnect the electrical connector from the washer pump. Press the release tab on the connector to unlock it, and then pull it straight off.

7. Remove the Old Washer Pump

The pump is typically held in place by a rubber grommet or a retaining clip. Gently pull or pry the pump out of the reservoir. Be careful not to damage the reservoir.

8. Install the New Washer Pump

Insert the new washer pump into the reservoir, ensuring it is securely seated in the grommet or clip. Reconnect the electrical connector.

9. Reconnect the Washer Fluid Hose

Reconnect the washer fluid hose to the new pump, ensuring a tight seal.

10. Test the System

Reconnect the negative terminal of the battery. Fill the washer fluid reservoir with washer fluid. Test the system by activating the windshield washers. Check for leaks around the pump and hose connections.

11. Reinstall Components

If you removed the wheel and inner fender liner, reinstall them. Lower the vehicle from the jack stands.
