I have a 71 Bavaria 3.3 5 speed I had it for 12 years and still trying to get it back up to speed. This past weekend a friend came over who was a BMW tech and used to work on these cars. We changed the thermostat and had to do a lot of bleeding to get all the air out. We finally had to jack the car up in the front and let it run for a while and leaving the bleed screw open. At first the bottom hose was cold but after a couple of tries it heated up. He also checked my battery cables. The negative cable was old so I replaced it with a new braided cable. He took a knife and scraped the surface before he attached it to cable connection point. He also redid the positive cable which joins 5 wires into the one connection. He separated all the connections with new ends that he soldered to each wire. He removed the bolt on the positive cable which has the hole for the other wires and put in a new more conventional battery bolt because the original bolt was starting to crack in the middle from age. After all this now my car starts right up on the first turn and idles pretty well. Next is tackling the brakes of a car that has been sitting for 12 years. That was the last time the fluid was changed. After that the drive around the block, hopefully in September !!!
