E46 Windshield Washer Fluid Pump and Grommet Replacement DIY doityourself
This DIY is for replacement of the windshield washer fluid pump. It will also be useful if you need to replace either the headlight washer pump, fluid level sensor, or the washer reservoir itself.
I know that this is a very simple DIY for most, but I also like to post up easy DIYs for those who normally don't feel comfortable working on cars so they can 1)see how easy it is, and 2) save themselves some $$$.
Symptoms: I kept finding a puddle of windshield washer fluid on the garage floor after driving the car far enough to get her nice and hot. I would top off the reservoir and find that it didn't leak... until I drove the car a long enough distance to get her hot.
Tools/Parts:
10mm socket
Pliers
Washer pump (part# 67128362154)
Rubber grommet (part# 89606011001)-- there are two different types of grommets: one with a filter basket, and one without. Verify which one you have.
1. Remove the 10mm bolt that secures the reservoir.

2. Now it's time to start disconnecting all of the stuff connected to the reservoir.
Disconnect the windshield washer pump electrical connection by pressing down the tab and pulling up on the connector. It is located on the backside of the reservoir.

3. Next, disconnect the electrical connector for the headlight washer pump located at the front of the reservoir (if so equipped-- if you don't have headlight washers, you won't have this).

4. Find the black "L" shaped plastic bracket that surrounds the windshield pump and lift up on the tab (arrow in picture) to remove it from the reservoir.

8. Now that everything is disconnected, remove the reservoir from the engine bay. Pull the windshield pump straight up. It will come out easily. Now use a pair of pliers to grab the rubber grommet and pull straight up to remove it.

9. Make sure that you have the correct grommet on hand. Some have the grommet with the filter basket, while some just have a rubber grommet with no basket. My car had the basket grommet. Press the grommet down into the hole until it seats fully.

11. Bring the reservoir back to the engine bay. Reconnect the fluid level sensor and headlight washer hose. Make sure the headlight washer hose is fully seated by giving it a few good pulls.
12. Reconnect the windshield washer pump hose.
13. Reconnect the plastic "L" bracket by sliding it from right to left and pressing the tab back into place.
14. Reconnect the windshield washer and headlight washer pump electrical harnesses. Make sure that they click into place.
15. Secure the reservoir with the 10mm bolt.
