Quick question
Good morning everyone,
A few months ago, the oil cooler was replaced on the truck due to the coolant being black. Fixed that problem, did a coolant flush and found out that water pump was leaking so it was replaced last week (no more leaking yay). Now coolant is disappearing. Personally, I don't think we added enough coolant to the system but as my help likes to point out quite often I have a limited/no knowledge of this stuff. There is still a little bit of oil that floats on top of the reservoir when it is filled up and little shiny bits of copper that float around in it. Would bad injectors cause copper flakes to show up in the coolant?
Thank you.

Any chance somebody added copper stop leak to the cooling system? The oily substance on the coolant could residue from the bad oil cooler if you didn't flush the coolant system good also could be diesel as well, if an injector cup is damaged you can get diesel in the cooling system.

Honestly, I have no idea what the previous owner did to the truck, the guy was kind of a idiot so it is entirely possible. He did not remove any of the gaskets from the oil cooler when he replaced it, who only knows how long the truck went with out an oil change before I did one (oil was chunky and moved like molasses in winter), rear tank was hooked up wrong, tail lights did not work, to name a few things.

I would start with a good coolant flush using tap water and dish soap for a few miles flush and repeat until you can't see the copper crap and oily substance. You can also add a coolant filter to help in the engine cleansing.
