·from MKIV FAQ:
"use a voltmeter, and attach the ground lead to the battery negative or the engine, then put the positive lead in the coolant at the radiator cap. it should measure less than 0.500 vdc, and ideally should be 0.100 vdc. more than 0.500 vdc is very bad and the coolant should be changed immediately. "
has anyone done it? I tried to measure i my coolant, but I couldnt get any voltage reading from it. my mixture is about 40/60 coolant/H2O
