Hi everybody , 2007 DTS changing antifreeze. I always was under the impression to use 50% prestone dex cool orange , and 50% distilied water ……...but looking through my manual , it says to use "clean drinkable" water. In my area I buy the gallon bottle of spring water. So I am curious what I should use. And yes , I believe you can drink distilled water. Ty , tim
distilled or spring water ??

Why not use distilled? I can buy gallons of it for the same price as the regular filtered drinking water that's sold in the stores.
oh yes slick , I have it here for a dollar a gallon. Just found it weird the manuall said to use clear drinking water ?? AKA , Spring or filtered drinking water. I will probably use distilled. tim
I'd go with distilled, little (if any chance) of contaminants. I figure the owner's manual reasons if it's fit for human consumption, it should be clean enough to use in your antifreeze.
Distilled water is drinkable but is "flat" and tasteless - it's absolutely pure H2O and nothing else, so no lime, scale, fluorides, chlorine, minerals, municipal additives like city, mineral, bottled boutique, or spring water.
Coolant contains several anti-corrosion, anti-foam, anti-acid, water-wetter, and water pump seal additives, so the less extra contamination it has to fight when mixed with 'water" the longer it stays able to do its job.
GM allows up to a 70/30 coolnt/water mix in extreme climates.

I am well versed in distilled water - a 1970s nuclear ballistic missile submarine on an 80 day patrol distilled over 10,000 gallons of it a day from seawater - to service the crew, cooks, reactor, steam plant, backup battery, and various equipment flushing duties. I made 16 patrols plus three 80 day "Northern runs" plus 3 ICEX (North Pole work) - so distilled water experience I gots. Nuclear power is wonderful - safe, efficient, lot of heat for doing good stuff - like making clean water.
Today's subs will run for over 30 years on a glob of enriched Uranium the size of your fist.
Backup battery ??? In case of a reactor scram (emergency shutdown) you need other power to restart - subs still carry a HUGE battery to supply that power - lead-acid cells, and they need distilled water to maintain electrolyte level. Huge ? How about 126 one ton cells (2.1 volts per cell) strapped in series with an instantaneous discharge rate of over 10,000 Amperes ?

Here's the Maneuvering Room in a Lafayette class (SSBN 616) missile boat. The panel nearest you is the SPCP - Steam Plant Control Panel including the ahead and astern turbine control wheels. The middle panel is the RPCP - Reactor Plant Control Panel - the little L-shaped handle moves the reactor control rods in and out of the core to maintain coolant temperature in "the green band" - about 450 degrees+. The far panel is the EPCP - Electric Plant Control Panel - lighting, battery, turbogenerator output, whatever. It was all fun............The average age of the men and women who operate every aspect these missile-carrying monsters is about 23.

I rode ROOSEVELT twice while a NATO observer out of Naples, Italy, COMSUBFLOT 8, in 1968 and 1969. Sixth Fleet. Helo on, COD off.
I went aboard the FDR 1962 and transferred to VP-30 at NAS JAX in 1965. You were on the ship just before it went to Vietnam.
Yeah, that. I volunteered for Swift Boat duty in-country but because of the '67 - '70 recent NATO staff duty they wouldn't let me go. Quartermaster. Sent me to instructor duty in Hartford, CT for 2.5 years. What a suck job.
timman, Sorry for the thread hijack a few posts ago ........
I've done this several other times, but ...................

our water supply here is from a reservoir lake. It's clean and sanitary but tastes like butt. Next town over has a spring that has been capped and routed to a pipe to just bubble up freely. Tastes great. Otherwise, I use distilled water from a home distiller we have. Been thinking about using that distiller to make some shine.
Heh, heh - that's back when OI was also used as a downrange tracking facility for SSBN submerged missile launch tests. Cape Canaveral and SoLant ranges. Been there, done that.
Where do you put the key to crank her over after an emergency shutdown?
After a quick double-check of the RPM (Reactor Plant Manual) procedures for the SCRAM reason, and voice conference with the Captain and Control Room watch, the Engineering Officer of The Watch orders the Maneuvering Room watch to "Commence fast SCRAM recovery !". Of course, there's one hell of a lot more going on behind the scene - it's an all-ship operation. The "key" is the orchestrated performance of over 18 crew members at the same time.
