I have a 1989 635 csi BMW and which needs the starter replaced. I was hoping to get some information on how to replace it. Two of my friends have been working on cars of there own for over 10 years. So I need to know how to get to it, where its located, and the best way to go about removing it. Any help would be appreciated

That all looks good on paper but from my experience you need to remove the intake manifold completely before attempting to remove the starter because it takes too much time and busted knuckles to try it without…. So do yourself a favor, remove before. Added bonus: you get to clean up the intake before you reinstall and this could be nice if you sell it down the line.
Most sockets won’t fit on the top bolt of the starter because of where it sits. So I took a 17mm socket and cut it with my Dremel so there was just enough left to grab the top of the bolt. Then I shaved down the sides of the socket so it would fit in to the top of the bolt to get a grip on it. Then I ran an extension past the oil filter and loosened the bolt. I told my friend who sold me my new starter, that I could remove and install the new one in under 30min. He said if I could do that, the starter would be free! Well, I don’t need to tell you who is driving around with a new, free starter!
