I have a 1999 540i and I'm wondering if anyone has step by step instructions for removing and installing a new water cooled alternator. This past weekend my wife and I were returning home from a week long vacation when I saw the red battery light come on in the dash. Being that we were between 135 and 145 miles from home I couldn't just have it towed. After a thorough inspection and a battery and alternator test I decided to have my battery recharged to full capacity, buy a fully charged back up and hit the road again this time with no AC or radio. We drove till it started getting dark, crashed at a hotel for one more night then got up in the morning to finish the trip. Now that we are home we have her 2002 325i and my 1986 944 to get around in and I've started talking to people about having it changed. I am having a hard time paying $450.00 for a reman alt, then another $400.00 to install it when I know that I can do it myself with the proper instructions. I don't have a "Bentley Brick" yet and so I'm reaching out to all of you. Thanks in advance as this is one of the first posts to a forum that I have ever made.
