My heater core was leaking when I got my ten09. Upon inspecting my radiator, it had mounds of white sand like material around each tube. Took it out to have out cleaned and was told it was bad as there was white sand like on the outside tubes as well where it was leaking. Ordered an aluminum radiator and installed a new heater core.

That's when I learned about electrolysis corrosion. Doing some research I found you get it hot, put your - voltage test meter wire on the negative battery terminal and the + into the colorant. Info said .03 volts was bad, mine was .08 volts. I flushed and cleaned the system, added orange anti-freeze and grounded my radiator at the low fluid sensor.

It seems to be a common problem when the anti-freeze is not serviced as required.
Good luck

Looks like the same stuff i flush out of water heater a white like pasty substance! Its from using tap water, the minerals and lime turn into that white sludge.....

Thanks for the help so far. At least I'm not alone. I hope to just flush it 3-4 times consecutively and get the junk out. Hope there aren't any hotspots in the block

Electrolysis corrosion of the aluminum on your engine. Thats what it ate off. I would flush it very well and get a good DIESEL coolant. Something with an anti-cavitant substance in it. It will help seal the metals.
