Begin with a small screwdriver to loosen the connector's clips and remove the power connection to your washer's pump on models made after 2001. First, take out the two screws that hold the washer reservoir and pump motor assembly to the fender well. Remember that later models put the wiper fluid tank and coolant storage tank together. Take the washer reservoir and then remove its small hose from the bottom. Close the hose quickly to stop washer fluid from leaking out. If possible, put leftover washer fluid into a clean jar for later use. Use a small screwdriver to remove the retaining ring stopping the pump motor from leaving its space in the reservoir. Hold part of the wall near the electrical connection with pliers, then gently draw the entire motor unit with impeller, seal, and pump off the reservoir. Drain the tank and wash it with clean water, looking for anything that shouldn't be there. When adding an old motor into a new water tank, first test and clean the pump area if needed. Apply graphite powder on the outside of the seal to make putting it in place simpler. Carefully push the motor end cap's little ridge into the reservoir's hole until the rubber ring presses firmly against the bottom of the motor holder space. Press the retaining ring into place by twisting a large 12-point socket onto it tightly. Attach one end of the hose to the base of the tank and place the tank in the engine bay, then tighten it with two screws. Complete your installation by connecting the electrical wires, filling the fluid tank, and running the pump to look for leaks. Only run the pump when there's enough fluid - otherwise, you risk damaging the equipment.
