3 years ago I replaced my radiator and flushed out the cooling system with some Prestone flush and 8 gallons of distilled water. Refilled with plain green coolant and distilled water at 50/50.
I've now just flushed it again the past couple weeks, I've put 15 gallons of distilled water through it. What I do is pull the lower hose which gets out 1.5 of the 3 gallon capacity and I then refill with distilled water. The first time I refilled with Prestone radiator flush and drove for maybe 2 hours. I had some soapy foam for a little bit to flush out after that.
It looks pretty clear when I pull the lower radiator hose, but I let it sit for a week and I changed the water pump, this is what it looked like when I topped it off (video below). It doesn't usually look this brown from the cap though.
My Jeep sees some offroad driving. Initially this was getting dirt from the dirt roads into the overflow bottle, which i fixed 3 years ago with a filter for the vent.
But it's still kinda brown. Is this still dirt? Rust? Once I get it clean I'll be using distilled water and Zerex G05 antifreeze (already bought 2 gallons).
