How to change the windshield wiper fluid bottle on 2001 chevy silverado or how to stop leaking of fluid without changing the bottle. Is there a product to plug up a leak?

Hello, I know of no product capable of a long lasting repair. You might be able to seal it on the outside with some sort of epoxy but a better fix would be to replace it with a new reservoir bottle. To remove it you need to unbolt that skinny brace above the battery and remove the battery and unbolt the top bolts of the washer reservoir. CAUTION, if you have the THEFTLOCK radio be sure to disable it before removing the battery cables. Set the parking brake and chock the rear wheels. Loosen the lug nuts on the driver's side wheel just enough to break them loose and jack up the driver's side and place a jack stand on a solid part of the frame, remove the driver's side wheel. Remove the inner wheel liner to give you access to the bottom reservoir bolts and pump, disconnect the electrical connector and unbolt the pump motor and washer reservoir, then slide it down and out, being careful of the small tube that carries the fluid to the wipers. Installation is the reverse, good luck and if you have any other questions don't hesitate to send a comment.
