    water was leaking out of a "weeping" hole on the water pump. This part was not very expensive. The part was equally not that difficult to replace, 9 bolts- and time. local santee shop quotes $365 for parts and labor.
    my friend, the right tools, and anafternoon. good times......good luck

    Noticed this problem by warning message of engine overheat.
    Mechanics told me it's water pump leakage after examination.
    After changing the pump, everything works fine until now (20000 miles so far).

    intake elbow keeps busting on engine at least once a year sometimes more. This needs to be recalled and made into a metal part or something that can withstand the constant heat and cooling depending on the temperatures outside.
