Yep. I got complacent and started filling the coolant reservoir with rain x windshield cleaner. In my defense they both have a yellow cap. Anyway I used my vacuum pump to get most of the contaminated coolant from the reservoir and then flushed the tank out till the water was clear. I only poured maybe 16 ounce in the tank before I realized what I was doing. It's in my dodge ram Cummins 5.9. Just consulting you guys before I waste money flushing my entire system to satisfy my OCD nature. Thoughts?
