How to remove windshield washer tank from a chevy cobalt lt

SOURCE: windshield washer reservoir tank is leaking how do I replace?

You must remove from it's mount and empty out any fluids that is in tank.fill the tank with water and locate where the leak is coming from. wash tank a few times and the let dry upside down. Get some sand paper (80  grit course) and sand area where leak is, clean area with a vacume or clean rag.you can buy a 2 stage epoxy that comes in an injection form and squeeze it out on a pc of paper and then get a q-tip and mix the 2 components together, fill the crack or hole generously with the q-tip, if you have to,let dry for 24 hours and mix more and put more on. let dry another 24 hours, replace tank back in it's place and you've solved your leak. (epoxy does wonders if its used properly.

Rear washer may have it's own reservoir . Can you hear a pump humming when you activate the washer? Look in the under flooor compartment

SOURCE: windshield washer pump is not working

not likely that fuse blew but check fuse box for wiper fuse and see if blown, when u fill fluid, turn ignition on but not running hit squirter and listen for pump noise if noise is present then hit repeatedly and look if there is any leakage dripping and trace leak, if no noise check resivor for debrie floating (posisible blockage) last thing is check for power at pump with wire probs

I had a similar problem. My first thought was that the reservoir was leaking but there were no holes in it. Then I noticed that the fluid hose had come off the hose junction fitting (above the passenger side fender -- hard to reach without taking off the panels) and fluid was siphoning out. Later on the hose came off again, and so when I had it in the shop for some other maintenance I asked the guys to look at it. They told me there was a pressure problem with the reservoir pump which was causing the hose to disconnect. They changed out the pump and it's been working fine now.

Remove the small tube that's attached to the fluid tank and press the wash button.
1 - If fluid isn't gushing out take out the connector to the pump and connect a light bulb to it. If the bulb lights up when you press the button the pump either is busted (replace it) or its connectors are corroded (clean them).
2 - if the fluid is gushing out then it's a blockage somewhere down the line; put the tube back in the tank, find and disconnect the other end, press the button. If it doesn't work then you have found the culprit - replace it. If it does flow then continue till you locate the blocked part.
