    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.

    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

    Water pump dripped on serpentine belt causing squeaking. Was an easy repair once diagnosed.

    Radiator fan runs almost constantly. There are no coolant leaks and water pump is fairly new (10K miles). I'm going to have the coolant flushed. Its my taxi cab and would like to get it to 400K miles.
