should I drain, flush and start over?

[monster1]

I installed a flush port on my 04 dodge 5.9 cummins today and flushed the system after I drained the coolant away (the Orange stuff) until the water ran clear. Autozone didn't have g-05 coolant so I bought the universal store brand. My system calls for about 6 gallons of coolant but I got just under 5 out of the draincock and reservoir. I filled the radiator with two gallons of universal. I went to grab my keys to get another gallon plus some distilled water to go to the garage to find my "helper" adding a gallon of the conventional lime green stuff I use in my older jeep. Grrrrrr. So my question is, do I need to drain, flush and start over or am I good with what I have. If I need to change it out in two years I'm ok with that. I just don't want to contaminate my system with the older conventional stuff because I hear it will cause problems in a g-05 based system especially if any g-05 remains to mix with the green. Please advise. Truck is sitting in the driveway until I get a definitive answer.

It will be fine short term but may form a dye sludge over time. I'd probably flush it again if you're picky about your system being clean.

Since it would require another gallon anyway, maybe I d should just drain it back into the bottles and use it for my jeep. I'll just flush the system and start over. Any precautions to make now that I have green stuff in the system?

That sucks. I would would flush and fill with new coolant

I would drain this stuff out and get some John Deere Coolguard II from any JD dealer.
This is made for diesels inc EGR diesels, it outperforms G05 and last 6 years. You can use test strips to monitor its condition.

I use this stuff in everything, gas and diesel and have no cooling system issues whatsoever over the last 5 years i have been using it.
It might be a PITA to get and its not the cheapest but well worth it.

Thanks for the replies. Unfortunately, I'm on a serious budget right now so the JD stuff is out of the question. If I leave what's already in there and add two more gallons of universal, and fill the rest with distilled water will I be ok or am I asking for trouble? My main concern would be the half gallon of conventional stuff that was added. I don't want to chance any gelling and plugging the coolant system.

Nevermind. I'm just going to do it right. Going to get three gallons of g-05 and three gallons of distilled water, flush and call it a day.
