Okay, I'm not going to get too far into detail about my love for BMW's, it's a Love Hate relationship, but I may have a problem. Tonight-Christmas all over again, Batt Light, Then Blast off heat gauge then engine light, in 20 degree weather at 80, maDE IT HOME, about a 5 mile DRIVE, SHUT HER OFF, AND THE SMOKE STARTED TO ROLL. nOW, SEVERAL HOURS AND a FEW cold ones LATER, POP THE HOOD AND FIND THAT THE BELT IS GONE. sO Does the the belt affect the waterpump and can I pull it in the garage, or am i about to find out tomarrow that the belt is the least of my worries after i pay to tow it back to the place. Been having crank sensor problems so i assumed it was just that, which im picking up a new one after having it cleaned up and just plugged back in last week. How do i REPLACE THE BELT, OR CAN I CANK IT OVER NOW AND DRIVE IT TO THE SHOP?????
