you turn 4b, you'll need a 17mm socket same size as the lug bolts. here are some pictures, they may be too small to view. I can send them as a pdf file if you want better quality pictures. I almost installed the whole new cooling system, new water pump, new pulley, new aux pump, new radiator hoses, new thermostat. I even took the expansion tank out and cleaned it with 6N hydrochloric acid to dissolve the metallic deposits. I am a chemist by training so I have easy access to those common lab chemicals.
