timing belt help 850

posted by  someone claiming to be mark on  Tue Apr 24 15:54 CST 2007 [RELATED]

I am changing the timing belt on my '94 850, which has ~240K miles. Belt was done 70K miles ago, at which time I also did the water pump. Should I change the tensioner this time around? Also the tensioner and idle pulleys? Runs into $200 extra for these parts. I will of course change the serpentine belt. Cam and crank seals seem OK, and I am reluctant to mess with them.

I would appreciate any input.
thanks
mark

    Tensioner every other belt change. The pullys have little tension on them, but they still need to be checked for play. Amazing how long those little guys last.
    I agree about the cam seals. So long as they look good, don't mess with them.

    I would definitely change out the tensioner and pulleys. A failure with any of them will take out your timing belt. I change water pump, tensioner and pulleys every other belt change. Cheap insurance.
