Before you start servicing the windshield washer reservoir, first disconnect and isolate the battery's negative cable. Subsequently, take out the front fascia, applying the proper methods for dismantling the front bumper cover. Remove the connectors from the electrical harness that attach to the reservoir and take out the hose to drain the fluid into an empty container. First, unscrew the rear mounting fastener, then remove all the other fasteners and finally, take out the reservoir from the vehicle.
