Hi to all, I have a 1986 Cadillac Deville and I was going to change the
Coolent in it. After I flush out the Water/Coolent I was wondering if
Distilled Water is better to refill the Radiator with or just use plain
old Tap Water. Is it worth the expense to buy Distilled Water ?.
Please let me know. Thank You.

For hells sake, don't put Vegas tap water in your car.
Not in the radiator, not the battery, I guess you can
use it in your windshield cleaner, but nothing else.
Use distilled water in your radiator and battery no matter
where you live.
If you live in the NW it is probably ok to drink.
If one were foolish enough to use ONLY distilled water, you're correct - it
would get nasty after a while. BUT the original question concerned what kind
of water to use during a coolant change.
Use ONLY distilled water. It's inexpensive, easily obtained, and doesn't
contain any trace minerals which could encourage deposits in the radiator.
Could you use tap water and get away with it? Certainly. But why? To use tap
water is sort of like buying an the cheapest oil filter you can find - why
risk it for a dollar or two?
Yes, the expense of distilled water is minimal and using it reduces the
minerals and other contaminants in your cooling system. I have used it
religiously for years and rarely have any kind of cooling system problems
with my vehicles.
Local Pepsi bottling plant uses local city water for the Aquafina
bottled water. In the Northeast, look for the "Bottled in" section,
it might just say "Bottled in Latham, NY from Latham municipal water"
or along those lines. People think they're getting better than tap
water when they buy a bottle of water, that may not be so...
Nope, bottled water tends to be "Spring" water, which comes with
minerals and trace elements (thus giving each brand of water its
distinctive taste that makes people want to buy that brand). It also
tends to be teeming with bacteria and such, but those will most likely
get killed off in any car's radiator once you hit normal operating
Water is only distilled when the label says it is.

???? Not saying it's not done, but I know of no one who uses distilled water
for baby formula, icky (well BF is icky already, LOL)
A lot of people use it in steam irons and it has a few other household uses,
but distilled water has such a flat taste (distilling removes the minerals, etc
that give water what taste it has)
Only the bottles they sell that are distilled water...
Is 50/50 a must ratio for the coolant/water mix? What happen if I just pour
coolant to the tank to top up the level? Why can't the manufacturer mix at
the factory? Sorry I'm newbie when it comes to cars and I'm curious to know
Thanks for your help,
