Hmm, that's too bad to hear. I have only put 10k miles on my saleri and no issues at all so far. Are you using 50/50 bmw coolant and water? Is the belt the correct length? Any imperfections in the water pump pulley that could make it significantly out of balance? __________________ ~Dave~ 98 328ti Morea Grun slicktop 11 128i space gray slicktop 13 JGC WK2 Deep Cherry Search | RealOEM |
