The alternator belt, which is the fan belt as well.. and the powersteering belt.. if you think you can make it easily there by stoping every now and then.. then go for it.. that is if you dont have AAA or something.. otherwise just take the bullet and call them up.. its what they are there for.. i just had to call them to tow my car.. my alternator belt snapped.. my passenger Alicia said she smelt some rubber.. i thought it was the BBQ place next door.. the point of that story... go with your instincts.. or your passengers..
