fwiw,
I guess I've never lived where the water was hard.
( California, Oregon, and some Washington State mostly ) ..
cause I have always used tap water......city tap water, with a good quality
anti-frz, in hundreds and hundreds of cars, with no problems ever.
I also add a spoonful or two of Mahinist's Oil....water souble cutting
oil...
makes a great water pump lube and rust inhibitor . Been doing that 20 years.
I hightly beleive in it.
I h ave never seen any corrosion in any cooling system that I've put
together, or serviced and maintained using this method.
I put Dexcool in one car. And have never bothered again.
Never saw that it was any better than a good quality ( that means Prestone
Exteneded Life to me ) anti-frz in a proper mixture.
and besides......
'what' you put in it, as long as it's pretty decent, is not as important as
how you take care of it ...
that it runs up to temp, that you change coolant regularily etc.
'sometimes' I'll add BarsLeak, but not normally. That's the only leak-stop
treatment I ever use, and that's more for a general treatment than for
patching up a real leak. And I sure wouldn't over-treat..
I've seen the bottom inch of a waterboxer water jacket be solid
'BarsLeak brown mud' - defenitely over-treated, but it got the van here.
( hmmm...I wonder if that's why that particular 2.1 waterboxer engine
has a funny sound in it, even with new heads and end-play on the crank
adjusted ...sounds like a playing card in a bycycle wheel sort of )
aloha !
Scott
