    polypropylene glycol?

    So the sears I work at is closing, and things are on clearance prices.
    There's marine/rv antifreeze on sale at 50% off.
    I looked on the bottle: it's propylene glycol. iirc that's the same as gm's dex-cool, right? ...as opposed to traditional antifreeze, which is ethylene. something like that.

    I've been looking this up. Seems that propylene glycol doesn't go down *quite* as low in temperature, but low enough for my purposes, and might be slower to break down (longer lifespan).

    Can I put this coolant in my car? It says "not for cars," but that might be a qualified "no."

    Will it form an emulsion with any polyethylene glycol left in the system?
    how are those "mixes with either one" coolants formulated anyway?

    And will it damage my rubber hoses, if there was any different chemistry there for a dexcool/propylene car vs an ethylene car.


    basically, can I use it (and should I buy some at 1/2 off), and what are some of the differences I should be aware of?

    Stay away from dex cool or anything that relates its self to that shit.. it eats away seals..all dex cool is, is GM job security. And plus the fact that all GM's run normal at 220 degrees LOL!

      it doesn't eat anything if you change it earlier than recommended (it's NOT a long life coolant like GM claims)


      what's this 220 degrees business?


      anyway...dex cool is ethylene glycol.

        If that is the pink stuff, most of them are labeled -50F, it is used primarily for winter layup as it is non toxic.

            The RV anti freeze is not for use in a car its for storage mostly for boats and RVs. There is one brand that is for auto use made by Evans Cooling systems (very pricy).

            The pink stuff used in a car when heated up erodes the metal in the engine.

              It doesn't have the anti-corrosive properties of standard coolant, even a propelyne glycol coolant. The non-freezing bit is not all the coolant does. It also lubes the water pump and prevents corrosion in the engine internals. the pink stuff doesn't do that. When it says not for use in cars, they mean it.

                pink is mainly for fresh water systems in boats and rvs. its run through the engine for winterization but not really meant for continous lube of the water pump.

                  http://www.evanscooling.com/ The only one that works. I have met with this guy at Ford to discuss usage of his coolant as OEM.

                    i know you all dislike cvn, but i suggest looking at the write up by user stalag it gives a rather interesting insight as far as coolant goes.
