    Q:
    How to replace the windshield washer reservoir on Cadillac Escalade EXT? Posted by Customer
    A:
    To replace the windshield washer solvent container you need to raise and support the vehicle to work safely. Disconnect both parts from the left front wheel area to work on the windshield repair. Use the wrench tool to disconnect hoses (1, 2) at the Washer Pump and the left side fender flange to drain washer solvent into a proper vessel. You need to disconnect power wires to reach the Hood Latch while the vehicle drops down. Take out the windshield washer solvent cap and the auxiliary battery tray if needed. Extract the windshield washer bolt from underneath the auxiliary battery tray when present and pull the washer container out through the wheelhouse opening to take out the upper windshield washer solvent bolts. Proceed to take out the windshield washer solvent unit. Move washer pumps and level indicator parts from old washer solvent container into new one before placing the windshield washer container assembly. Put the upper windshield washer container bolt onto the auxiliary battery tray if present and connect it securely. Afterwards, screw in the upper windshield washer solvent container bolts and tighten them to 9 n.m (80 lb in). Reattach the windshield washer solvent cap while you also install the auxiliary battery tray when it exists and then properly link both electrical connectors and Washer Pump hoses (1, 2). Replace the left front wheel components by returning the wheelhouse liner and wheel assembly. Also refill the washer solvent tank with designed windshield solvent.

    Q:
    How to replace the windshield washer reservoir on GMC Sierra 1500? Posted by Customer
    A:
    When replacing the windshield washer solvent container start by jacking up the vehicle and removing both the left front wheel assembly and wheelhouse liner before you can lower it down. Before working on the vehicle you should remove the lower outer bolt from the washer container. Unplug the pump lines (1, 2) from the left side fender flange and let the washer solvent collect in a proper container. First disconnect electrical wires then lower the vehicle to the hood area and unlock the hood. Take off the windshield washer solvent cap and the auxiliary battery tray if present before removing the bolt that holds the upper windshield washer container below the battery tray. First separate the washer container from the bottom of the vehicle through the wheelhouse before taking out all the upper windshield washer solvent container bolts and its complete assembly. Put washer pumps and level indicator parts on new washer solvent container before attaching the windshield washer system components. Secure the washer bolt to the auxiliary battery tray if present and make sure to fasten the upper windshield solvent container bolts to 9 n.m tension. Attach the Washer Pump hoses (1, 2) after joining the electrical plugs and placing on the windshield solvent cap. Put the lower outer washer bolt in place and install both wheelhouse pieces and wheel components before adding windshield solvent to the washer container.
