Respuesta a "How to replace the starter on a 1989 635 csi BMW?"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!
