How to Remove a BMW 3 Series Windshield Reservoir


Instructions
1. Crouch next to the front-passenger wheel well and notice the bolts holding the front inner-fender well to the BMW. Remove these bolts with the socket wrench and tuck the fender well out of the way.
2. Pull back the inner bumper slightly and notice the large white tank with a black cylinder attached to it. These are the windshield-washer reservoir and washer pump, respectively.
3. Detach the power cable from the pump by depressing the tabs on either end of the plug and pulling it off the socket. Pull the delivery hose off the pump nipple opposite the power socket.
4. Shine the light of a flashlight into the cavity housing the reservoir and note the two hard-to-reach bolts securing the reservoir.
5. Remove the two bolts securing the reservoir using the socket wrench with an extension, turning left to loosen.
6. Gently pull the reservoir out of the cavity by pulling it toward yourself and rocking it to the left and right to work it out of the cavity and past the inner bumper.
