    Hot Rods Water Pump Repair Kit

    Dan in WY

    Second kit had more instructions and assembly tool

    First kit had very little instructions, installed it and it started leaking within 2 hours. Second kit had full set of instructions and a plastic spacer for setting the mechanical seal, this one lasted 14 hours. All other seals and bearing in kit work and fit perfectly, will try an OEM mechanical seal next.

    What's recommended

    from the factory. Knowing it is the correct micron and dimensions over a cheaper filter is worth the extra money for a factory filter.

    A must have tool for any tool box.

    This tool comes in handy for all my little jobs and some big ones. It is pretty sturdy and well made. the handle is large enough to get a good amount of torque on the screw or nut being tightened and so far the tool has been very durable and not let me down while being used.
