    GT-40 water pump

    The water pump on my 1996 SN is making a squeeking sound. It looks like the pulley on the pump is kind of wabbling as it spins around. The impeller is brand new this season and looks to be in good shape with about 25 hours on it. Do i have a bearing or something going bad with my pump?

    Mine went out last year at 600hrs. If it's wobbling your bearing may be going bad. Many say you should see leeking but I never did until it disintigrated. When I replaced mine the dealership told me as a general rule of thumb you should replace them at five years or five hundred hours.
