    Thermostat Direction!!

    This may sound like a stupid question, but which way does the thermostat face on a 93 4.3 CPI engine?? I'm confused because of the reverse rotation water pump.

    It goes the same way as any other thermostat with the spring down in the intake.

    And as far as the water pump goes, the water doesnt flow any differently in the motor, heads, rad, etc.

    Its just how the water pump spins, because of how the belt is routed with the other accessories.
