How to Replace the Windshield Washer Reservoir

1. Open up your hood and locate the windshield washer reservoir. This is typically located along the edge of the compartment.
2. Try to identify visually whether or not there is a crack in the reservoir. You may have to pour some more washer fluid into the tank to see where it is leaking from.
3. Remove the windshield washer reservoir if you can't find the crack while it is still installed. Consult your manual to determine the best way to remove the reservoir. On some cars you can unscrew the tank from above, but others require you to access the assembly from beneath the car.
4. Order a new reservoir to replace the old one from the parts supplier for your car. Some dealerships have parts available for purchase. They may have a replacement reservoir in stock, or they can order one for you.
5. Reinstall the new reservoir. This involves screwing the tank into the assembly, attaching the hose between the tank and the motor and reattaching any other leads such as those to the electrical system. You will also have to replace the seals.
