Ha-ha-ha! I guess I'll be drinking distilled water for awhile...
(which I like because it's pure water and there is a difference that I can feel - but some say it will leach out minerals from the body- likely true if you drink it frequently) It might leach out bad stuff too though.
I bought 14 gallons of distilled water last night
just to get started with flushes today
and was planning to buy more today.
I was going by a frequently discussed method at FTE forums, called '*****'s flush and fill', or something like that.
Whoever ***** was, he knew a lot about coolants back in those days (10-15 years ago). The main discussion was in a Power Stroke Forum. There was even a seminar in San Francisco where people brought their trucks somewhere to learn how to do this. One guy who posted about that seminar (if I remember correctly) mentioned starting with 40 gallons of distilled water with a child's plastic wading pool from Walmart for a drain pan, then he had to send someone out to buy 16 more gallons of distilled water before he was finished. That would be 8 flushes with distilled water, also wasting fuel and being soaking wet for an entire day.
I've always thought that method was crazy and I mentioned that in an earlier post in this thread. After reading your comment here I was thinking: The cooling system in a big cast iron IDI diesel is obviously not a sterile laboratory for medical research or a sterile surgery room for doing brain transplants.
However, my technical mind had overtaken my practical and common sense mind as I thought:
Very technically in terms of chemistry, distilled water will likely work a little bit better for a final clear flush, help remove some small amount of lingering minerals or a little bit of chemical residue from a chemical radiator flush but now today, after your comment I realize again it's a cast iron diesel engine, not a sterile biochemistry lab.
So, I've opened a jug of distilled water and on my second cup
I'll be in the kitchen making a pot of coffee with it. That should be good coffee.
I really do have something very important to add to riotwarrior's tech instructions on replacing a thermostat- it's important enough to prevent potential unwanted damage that some people with a different year of vehicle might experience.
I'll have to get to that later because again it is not raining right now and I need to get some more work done on my truck first. I bit off a lot to chew on this job, with this weather. I will post the information here later though, with a photo or two and send a PM to riotwarrior about it.
