First, open the hood and take out the negative
Battery Cable from its post. Put an A-frame under the car, lift and slide a 2x4 between the fascia of the left side and the body to raise it. Remove the wire connectors from the reservoir pump, then carefully lift the pump out through the grommet spot, without hurting the reservoir. Take the rubber grommet from the top of the reservoir and throw it away. While installing, operate in reverse. Get a new rubber grommet for the new pump, put it in place and check if the pump is seated properly in the reservoir. Once you swap out the reservoir pump, don't forget to refill or replace the washer fluid.
