a few things:
First: Checking my coolant from my petcock valve (93 F250 7.3) and what came out first was a dingy red color, then followed with green. Upon checking the coolant from the rad cap, it’s green. Is the red just rust? Or does that sound like it’s a mix of red coolant and green coolant?
Second: conducted the test and the molybdate was damn near white. Row 0 if not less. With the nitrite color at column E which was most accurate, that put me at 1.2 marked by a black dot on the sheet provided in the picture. I’m planning on flushing the whole damn system anyways, but I’m curious, how does all of this sound? Is this an “oh ****, I wouldn’t drive your truck until you flush that coolant” moment? Or is it okay until my DC-8 comes in the mail and I add some in. This is my daily driver and I love this truck so I’m really trying to avoid any cavitation.
Third: what coolant do I need to mix with DC-8? There’s so much information on the internet for this stuff, I swear you can read one thing and then read the complete opposite in the same forum thread. I’m considering getting my hands on CAT ELC but until then, what will the DC-8 mix with safely?
