    Water Pump Swap

    Hi

    I recently changed the water pump to the screw on version by accident and now in the process of changing the fan clutch and pulley to match.

    My question is besides the 130mm pulley and the screw on clutch, is there anything else i have to change? Belts etc?

    A 144mm pulley will work with the screw-on water pump.

    13x1055 belt.

    What belt are you using? What alternator are you using? Is alt fully loose?
