I don't know kschachn, as I am no way a mechanic but I received this car back in 2014 when my aunt passed away and it had less than 34,000 miles on it. I did a complete change of all the fluids including a radiator flush plus replaced the thermostat with a brand new Motorcraft stat . Radiator fluid was pretty dirty then but flushed clean and I had no problems. In 20016 I flushed again and installed a brand new motorcraft water pump , idler pulley and tensioner along with a brand new belt. It was here when I started to have temp issues as it would just shoot up within 20 minutes of driving . I never overheated but it made me very uneasy . I had two different mechanics check on it and both said it was fine but I just kept seeing much higher operating temps than I had seen before and I had no loss of fluid in the reservoir tank so I was baffled. That is how I came to use RMI and you are probably right it probably did not help like I think it did .

Another RMI-25 fan. I had been using it for cleaning and was happy with that. but the documentation claims it contains pump lube and seal conditioner. So I tried it on a Toyota with a weeping water pump. I'm not claiming it "worked". Because I can't prove that. But I can say the weeping stopped for the last year of ownership.
Anyone try RMI-25 to clean up Dex-Cool mud? I drain and fill every few years to keep things clean. But I still get some orange goo in the resevoir, small hoses, heater core ports, etc. Not real bad, but i would imagine over time that will build up.
