Ford Aluminum Body
Sorry fellows. Having problems posting and I give up
Forum Discussion
Technology...AKA "Laws of Physics" discussions here goes in circles...
Look up "galvanic action", "how batteries work", "chemistry of a battery", "water conductivity", "water resistance", ETC and follow the footnote reference links on all of those sites
Just because a designer/engineer did the work, does it mean they got it right.
Take my GMT400 1996 Suburban (all GMT400's) with rear AC. They designed it with aluminum tubing that mated via flare joints to copper tubing.
Sounds like nothing major, right?
Well it was found that those flare joints could NOT be undone without breaking one or both tubes...because of galvanic action welded themselves together
There are tons of designs out there where they screwed up by not understanding galvanic action
Another is DeathCool (DexCool or OATs) coolant. Just by the way OATs works..left acid in the coolant. It is to strip all metal to allow the organics to plate a protective coating.
But...stripping off metal will then have metal floating around in the coolant...and not all the same metal, but a mixture of whatever to form a battery in the cooling system (galvanic action)
Just look up the diagnostic HOW2's on OATs and HOATs based coolant systems. Some will have a sensitive DOM (digital ohm meter) and if the votage is above a certain level...cleanse and change out the OATs/HOATs coolant...the why is that with the dissimilar metals being connected via conductive coolant...makes a battery that will erode the cooling system...even rubber hoses...
