Electrolysis

[bpolly2004]

Hi all. 2009 ram 1500 5.7. 215k
In 2 years I've had to replace my radiator and heater core. I am about to have to change out the heater core again. No heat on drivers side. I've flushed it and it got hot for a couple days and now it feels like ac blowing on me. So I tried to measure the voltage of the cooling system with my multimeter. In dc mode the reading was all over the place. In ac mode it was at .010. So I don't think electrolysis is my problem. What else could cause this?

Are you sure it is the heater core and not a temperature mode door misadjusted or sticking or with a bad actuator?

Take a look through the HD section,and do a search on here,there's probably 50 threads on the issues you're dealing with

Casting Sand: 6.4 Hemi HD Coolant Filter

PFA. I’ve noticed a bunch of people dealing with casting sand in their coolant that clogs up their heater core. Seems to be a big enough issue with the penstar that there’s a class action lawsuit over it. I’ve got a continuous flow of casting sand in my 2014 2500 6.4 w/140k miles I’m hoping...

Did you flush the whole system or just the heater core? If you didn't flush everything there still could be crap in the system that keeps floating around til it makes its way to the core and clogs it.

I flushed everything.

If you’ve got heat on one side not the other, it’s not the core.

use an air water flush gun and push into the block the crud will come out if the lower radiator hose.

The best part of rmi-25 is it insulates the cooling system from electrolysis, it also takes any contamination and traps it in over flow tank. Once you open it you need to use the entire bottle it doesn't store well once o2 hits it.
