Take off the two screws that join the pump body to the washer reservoir for all models made from 1975 onwards. Next, disconnect the electrical leads and hoses. Follow where the motor and pump are set in the reservoir, then take off the nut and filter using a proper socket and wrench. Replacing and installing the pump motor needs the entire unit gasket, retaining nut, and filter installed at once. First reverse all steps you used to remove the pump.
