I just did mine today. I just wanted to share some things :
- I didn't have to remove the reservoir. Just removing the bolt gave me access to the pump and I was able to remove it without any problem.
- In my case, even if I changed the pump and the washer, just changing the washer would have fix my problem. My pump was still working perfectly but the problem was it was always leaking and I didn't know where was the leak.
Took me 5 minutes because I didn't remove the reservoir.
English is not my first language. Sorry for the mistakes.
