Reassemble your Toyota Corolla. Put the new windshield washer reservoir in your car by screwing it into place, replacing the mounting bolt and attaching the hose and any other leads. After that, reconnect the battery and electrical connector.
Put the inner fender liner back together, replace your tire and lower your Corolla to the ground.
Tips & Warnings
If the crack in your Corolla’s windshield washer reservoir is small, try patching it rather than replacing the whole reservoir.
To increase your chances of finding the leak, pour some washer fluid into the tank.
