Sat morning and it's raining outside as predicted, so time to go attack the belt on the 128. As it turns out, I did find a video on how to replace the belt. Now, that said, this video is for the e9x cars, but since they rock the same motor and configuration, this should work just fine. What I do like is they give the torque values for the replacement aluminum bolt, which is 25n/m, or in my world, 18.4ft/lb.
He initially talks about removing the pins for the front intakes. I didn't find those pins, but the screws holding the intake in are there, so that is a valid part of the video. About to put this to the test, so back in a bit. Below is the best video I could find...
Many thanks to "AskTheCarExperts" for producing this video...
