Changed out crank pulley to a 4inch billit alum.Now my temp went from 170 to 190 at idle.The old pully was 7.5in diameter but really warped.Will something like RED LINES additive really lower water temp 10-30deg? Would like to try this first for $8.00 instead of electric fan or reinstalling a factory crank pulley.Am I waisting my time?
