if you can read voltage in the water of a radiator , then there is a problem and the water needs to be drained and flushed and new antifreeze installed . if you are using full strength antifreeze, it must be mixed 50/50 with distilled water only. never use tap water in a radiator ! Thanks Jim T
Another viewThere is a specific problem that can be checked with a volt meter, I do this every major service (spring and fall)I check coolant voltage with engine running to engine block and chassis.
If you read more than the error level for the meter you have a ground problem and this is grounding through the cooling system and will damage the cooling system. Most likely the radiator

you may have a short in the ignition swith get test checked, a steering column specialist can do this in a couple of minutes
Low on coolant or a sticky thermostat, replace it.
Check the bulbs first. Then check the fuse. If the bulbs and fuse are good, check the relay under the hood (you will have to take it to an auto parts store to have it tested unless you have a volt meter and a nine volt battery).
Have it checked out. Probably engine coolant working its way into the oil. Possibly head gasket and/or cracked head at fault.
There is no such thing as a proton volt.
