How to Repair Windshield Washer Reservoirs
- 1). Look in your owner's manual for the location of the windshield washer reservoir. It is either on the driver or passenger side of the engine compartment.
- 2). Kneel down by the wheel well that is on the same side as the windshield washer reservoir. Remove the bolts or pins holding the inner fender, or spray shield, to the inner bumper. Peel the inner fender back and tuck it behind the tire to reveal the cavity that houses the windshield washer reservoir.
- 3). Unplug the power cable and delivery hose connecting the windshield washer pump. Aim the flashlight deep into the cavity housing the reservoir and note the bolts connecting the reservoir to the vehicle. Remove these bolts using the socket wrench with the long extension. Pull the reservoir out of the vehicle.
- 4). If the reservoir is dented but not cracked, use a coat hanger to push out the dented wall from inside the plastic reservoir. Unwind the coat hanger and insert the hooked end in through the reservoir's grommet. Press the blunt side of the hook against the dented wall until the dent has been pushed out. If the tank is cracked, continue to the next steps. Otherwise, skip to Step 7.
- 5). Pull the pump off the side of the reservoir and place it aside. Empty any solution left in the reservoir and clean it using soap and water. Dry it using the paper towels.
- 6). Open the plastic tank repair kit and sand down the surface that is cracked. Spread some rubbing alcohol from the kit onto the surface. Mix the two-part epoxy from the kit, and brush the epoxy onto the fiberglass cloth that comes with the kit. Lay this cloth, or sheet, over the crack in the reservoir and let it cure for an hour.
- 7). Reattach the washer pump to the side of the reservoir. Insert the reservoir into the cavity of the vehicle, and remount the bolts. Reattach the power cable and delivery hose to the washer pump, and unfold the inner fender well, replacing the bolts that hold it to the inner bumper.
