Im getting ready to flush my coolant and put in one of those 180 degree thermostats. But I get my water from a well, so it's full of minerals. Should I buy some distilled water or will it be fine running my well water? I'm just worried about the deposits that it may make (since I see ample evidence of them on faucet heads and such in my house.)

Another thing I just thought of. Will my local autozone take the old stuff? Is there usually a charge?

You might want to do some research before you use distilled water - it is de-ionized, and is not recommended for cooling systems. Might want to look into using de-humidified water, or try some of the many brands of antifreeze that come already mixed as a 50/50 solution.

Note the section on SAE J814:

Quote:

Clean potable water, low in chloride, sulfate, and hardness is generally acceptable. Brackish or undrinkable water should not be used. Softened, deionised, or distilled water is ideal to dilute engine coolant concentrate.




I don't think it unreasonable to trust the Society of Automotive Engineers. Do you have links or other documentation to back up your statement? I just filled my SVT with distilled water two weeks ago; I really don't want to do another flush if I really don't have to.

Distilled has always been the standard because of its level of purity. It's the best choice.

I don't think its unreasonable to trust the SAE, either. But what I was trying to point out was that, since I had heard many years ago that putting distilled water in the cooling system was not a good idea, tutmondigo might want to do a more current search to see what the latest info was.

I was not able to find the SAE J814's actual text on the net to see what their paper actually said, but you can go to www.No-Rosion.com/faq.htm/ and see one company's comments about using distilled water in cooling systems.

And please don't do another flush based on my comment. I was only suggesting that everyone should do their research and make their choices.

Hope you don't mind me hijacking this thread: last time I did this job, it took forever and was messy as h*ll. Any hints?
