    Definitely need to test with another gauge or 2.

    How about checking the thermostat, or a different one.

    Check temp with another guage, and make sure to have proper shrouding around the cooling fans.

    No shroud = over heating issues
    High flow pump = over heating issues
    Too cool T-Stat = engine wear issues
    Incorrect timing = over heating issues
    on and on......

    A high flow pump wont cause over heating issues.

    The Radiator is basically a heat sink.. The more you can push through it the more it will cool.


    As for OP.. Stock pulleys?

    I have to agree with COPO. I have seen a high flow water pump cause a car to overheat, because it was moving the coolant too quickly through the radiator which didn't allow enough time for the fluid to cool.

    The high flow water pump can also push the water thru the engine too quickly, not allowing it enough time to pick up the heat.

    You cannot push water in "too quickly" through a block.
    The more flow the better cooling.
    I would almost guarantee the person had under drive pulleys or some poo that caused the issue.

    More water movement both through the block and radiator will always cool better. Water will conduct the same moving slowly as it will moving quickly, its a matter of pressure and volume that you must look at.
    As pressure increases the less likely water is to boil or "flash"
    The more movement from the more volume will give a better cooling effect. You make the point of it moving too quickly. Water doesn't care how fast its going.. its still surrounded by hot metal and will take away heat.

    Straight from Stewart Componenets:
    Q1. Will the Stewart Hi-Flow water pump reduce my cooling temperature?
    A1. Yes. The water pump is the heart of the cooling system and flow should always be maximized to reduce temperatures.

    I believe this was discussed here once or twice.
    And I'm pretty sure the consensus was too much water pump was a wives tale.
