Windshield washer pumps wear out over time and tend to wear out quicker if you live in a four season climate. If you live somewhere where the weather gets below zero it is very important that you use the correct windshield washer fluid and do not just put water into the system. Proper windshield washing fluid not only has mild cleaning properties it also contains an ingredient to keep the fluid from freezing. If the fluid freezes in the system it will expand to the point that it can damage both the lines, pumps and reservoirs. Make sure you always have to correct fluid in your system.

Begin by suctioning out as much of the fluid as possible. Once you remove the pump whatever fluid that is remaining in the reservoir above the pump will flow out through the pump grommet.

Over the years your car may have been serviced by multiple people including previous owners and this can lead to parts replaced with different size fasteners and hardware. The sizes of the nuts and bolts we give may be different from what you have so be prepared with different size sockets and wrenches. If something is different on your vehicle please let us know and share your info to help other users. If you have any questions or comments or even a different procedure you would like to share please leave it below and please leave your vehicle information.

You will need to remove the front right wheel well liner to work on the pump.

Begin by removing the two locking Phillips head screws on each side at the rear of the splash shield.
Figure 1

Begin by removing the two locking Phillips head screws on each side at the rear of the splash shield. As you turn them, they eject from the sub-frame, releasing the rear of the shield. Remove the three 10mm bolts securing the front of the lower splash shield and also the lower edge of the front bumper cover. On cars with the aerodynamic package, the two outer bolts are hidden up under the bumper cover. Loosen the bolts and slide the splash shield out.

Now remove the right side wheel so you can access the wheelhouse liner.
Figure 2

Now remove the right side wheel so you can access the wheelhouse liner. Remove the two Philips head screws as shown here (green arrows).

Next, locate and remove the plastic expansion rivets securing the liner to the wheelhouse (green arrows).

Shown here is one of the plastic expansion rivets being removed.
Figure 4

Shown here is one of the plastic expansion rivets being removed. When the center screw part is pressed into the outer part, it drives the fingers outward, locking the rivet in place. Sometimes, the outer part will turn with the screw as you try to loosen it. If it does, hold the outer part stationary as you loosen the screw part.

With the right wheel well liner removed you can see the reservoir and pump (red arrow) located between the fender and chassis.

Squeeze in the tab on the top of the electrical connection and separate the connection by pulling it straight up (red arrow).

There is a stub on the pump that sits in a notch in the reservoir (red arrow).
Figure 7

There is a stub on the pump that sits in a notch in the reservoir (red arrow). Gently pry the pump out from the reservoir notch.

Now you can wiggle and lift the pump out from the reservoir (red arrow), remember that if you have fluid above this level it will drain out once you remove the pump so be prepared.

With the pump out you can carefully pull the two lines out from the pump (red arrows).

Installation of the new pump is the reverse of removal and don't forget to refill the reservoir and check for leaks.
