Chevrolet began manufacturing the Silverado, a full-size pickup truck, in 1998. Fortunately for all years of production and models, installing the windshield washer tank follows the same procedure. The windshield washer system, including the hoses, pump, motor and wiper blades, keeps the windshield clear of rain and debris. The windshield washer tank, or reservoir, holds the washer solvent that's pumped into the washer nozzles and sprayed on the windshield. Installing a windshield washer tank is a straightforward process; however, it does require a long extension for a socket wrench set, because the bolts holding the tank are deep inside the engine compartment. With this tool, you'll be able to install the tank in under an hour.

  1. 1

    Access the compartment where the windshield washer tank resides by removing the two bolts holding the passenger-side inner bumper well in place. This inner bumper well is in front of the tire. Remove the two bolts using your socket wrench and tuck the bumper out of the way.

  2. 2

    Pull the inner bump away from the vehicle slightly to reveal the location of the windshield washer tank. If there's already a tank there, remove it by using the long extension with the socket wrench to unscrew the two bolts holding the tank in place. Disconnect the power cable and the delivery hose from the washer pump, which is attached to the tank, and pull the tank and pump out of the Silverado.

  3. 3

    Look inside the area where the tank was and notice the position of the small orienting orifice or depression. Orient your new windshield washer tank so that the nipple is facing toward this orifice.

  4. 4

    Pull back the inner bumper and insert the new tank into the area where the old tank was, lining up the tank nipple with the orienting orifice. Brush the delivery hose and other cables out of the way, and work the tank into the area with a back and forth, or wiggling, motion, as there is not much room to move.

  5. 5

    Place one bolt on the long extension of your socket wrench set. Line up the windshield washer tank hole with the rivet, and insert the bolt into the rivet. Tighten the bolt in the rivet enough so that the bolt does not fall out. Repeat this step for the other bolt.

  6. 6

    Tighten both bolts in their rivets, turning once past snug. Connect the power cable and delivery hose to the tank pump, and push the inner bumper and bumper back into place. Reinstall the two inner bumper-well bolts you removed earlier.
