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

whats a good mixture of coolant/water?
I know water obsorbs heat much better than coolant thats why I start adding alot of distill water, I just wonder if there is a certain amount of coolant I should at least have in the system...
of course I'm in California so I dont have to worry about antifreez.

Jonas,

20% coolant, 80% distilled water, a bottle of Water Wetter and the TRD 1.3 radiator cap are your friends.

Change it once or twice a year.
