This is what I run on my 1.9D, installed a cast iron WP pulley from an AC-equipped Rabbit, had to machine off about 1/8"
material on the inside of the mounting flange to line up the belts. The increased pump speed dropped coolant temps about 1/2
mark on the gauge, where it used to rise up just a bit at speed it now stays the same. Running the same belt as before.
