  Q: How to replace the windshield washer reservoir on GMC Sierra 3500 Classic?

  A: Before you can replace the windshield washer solvent container you must raise and stabilize the vehicle. Disconnect and remove the left front wheel assembly plus its liner. At first remove the lower outer bolt from the washer container when lowering the vehicle. Take the Washer Pump hoses (1, 2) off their connections to the fender flange and collect windshield washer solvent into a safe receptacle. Disconnect the electric wires followed by lowering the vehicle until you can reach its Hood Latch and open the hood. Disconnect the windshield washer solvent cap and the auxiliary battery tray if present then pull the washer container bolt out from under the auxiliary battery tray. Take out the washer container from below the vehicle through the wheelhouse opening. Disconnect the upper windshield washer solvent container bolts first before taking out the washer solvent container unit. Move washer pumps and level indicator hardware to the fresh windshield washer container and connect the whole washer solvent assembly. Install the bolt that connects the upper windshield washer container to the auxiliary battery tray when present and torque the windshield washer container bolts to 80 lb in (9 N.m). Install the auxiliary battery tray back into place when necessary and secure the windshield washer solvent cap. Secure Washer Pump connections and hoses (1, 2) before installing the bolt on the lower outer container. Reattach the left wheelhouse and wheel parts before filling the solvent container with windshield cleaner.
