This is my reading with distilled water only.





This is my reading after adding 1 gallon of pure antifreeze(not 50/50) to my existing distilled water(removed 1 gallon of water first yes).

Her's a link to a site with a lot of good info. Looks like I'd better get after my truck. My voltmeter reads 1.1 Volts! These guys say it should be below .3 Volts. They also say to use distilled water and that the reading may take some time to go down after flushing and filling with new coolant, as the antifreeze removes the residual contaminants in the engine.
