I have a 2011 6.4 hemi swapped into in a 69 truck, and a griffen radiator. with engine not running, and cool coolant. 100MV. warm engine and coolant circulating. I get a radiator Eating reading of 650mv I used a zinc anode it looks like new, i have added grounds and moved them around to different spots. still the same readings. i also removed the coolant and replaced it with RO water and royal purple PURPLE ICE......didnt help. Sounds like you have a stray voltage if you are getting that much of a change in voltage while running. More going on than the fluid in the radiator. I do not get a major difference in voltage. I'm around 80mV with less than 10mV change when running and hot. I have a couple Justice Brothers products that might help, but they are not going to fix a bad ground. They are specifically made to reduce electrolysis with metal deviators to help with grounding between dissimilar metals.

I was just reading a similar story in FBBO about an electrolysis issue. His problem was due to lack of/bad grounds and faulty switches causing feedback.

I was just reading a similar story in FBBO about an electrolysis issue. His problem was due to lack of/bad grounds and faulty switches causing feedback. He was getting a whole 3 volts of stray voltage in his cooling system. He said he fixed a bunch of grounds and went through his electrical system circuit by circuit. That knocked him down to .3 volts, but he would still get an increase/jump in stray voltage to .8 volts when the car was running and being started. That lead him to replacing the old ignition switch. Wonder if 70blackfish could bypass the switch or "ignition on" related items and see if things changed. Might not be so easy with a car with modern electronics though?

If you have a zinc anode, relax and forget about it.....check the anode in a couple years.

The zinc will not eliminate the voltage as it decays, it will simply become the #1 target and decay before anything else does. Just because the voltage is there does not mean it is eating your aluminum parts (YET), and the rate of decay on the anode will be quite slow. Have you lost a heater core or radiator since the anode was installed?

the electrolysis is NOT eating the radiator, that why you have the zinc anode.....quit worrying about nothing.
