HI, just bought my first BMW (1997 328i convertible with 110,000 miles/black on black with auto) and had a weird noise start up/right AFTER I brought it home. When I start it cold, there is an odd "clinking" sound by the front fan hub. After 20 minutes or so, it would dissipate. I changed the fan hub, water pump, T stat and housing, belts and fluids. Ran and sounded fine for several days then it started up louder then ever. When I spray WD40 at the AC belt tensioner, it goes away. Should I replace the lower tensioner and pulleys? Can that be the problem. WD40 clears it up right away.
Thanks for the help!!!
Will be shortly adding mods and pics - great cars (I'm an old Alfa racer - lousy mechanicals).
