Although the coolant formula may vary by country and manufacturer, the basic composition of the mixture is as follows:. Depending on the substances used for their production, their type can be divided into organic, inorganic or hybrid; the latter is also known as OKT Organic Acid Technology. This idea is widespread, but this is a misconception. The coolant is transparent, like water, and the reality is that manufacturers add dyes to its composition in order to identify with the brand.
This is just a marketing ploy. However, the expressive color of this fluid is critical to the workshop as it facilitates the determination of the location of a leak in the circuit. Manufacturers' recommendations regarding control and replacement depend on the characteristics of each car, although it is usually advised to replace it regularly usually every However, you should consider replacing it every time the season changes, as with increasing temperature, for example, the liquid may evaporate.
In addition, the following considerations should be kept in mind:. It does taste sweet and ultimately causes kidney failure. Diethylene glycol is also poisonous. Polyethylene Glycol is not poisonous but it does do a great job of getting you ready for a colonoscopy.
Propylene glycol is also safe as a food additive and also is called RV antifreeze. Read this in Mother Earth News in the '70's and I tell everyone that I know who has dogs, or other animals.
Speed is of the essence. Get Advice for Treatment. At first sign or if you suspect poisoning - begin treatment. I have helped to treat a number of dogs, who went on to live long lives.
A couple day hangover is better than a prolonged death. Darryl in Fairbanks. I can remember in the 40's,Daddy would drain the stuff out of his car and shore it under the porch until fall. The reason for using alcohol was the new "permanent" antifreeze was expensive by comparison, especially for old cars that tended to leak.
I did know a Model A owner who drove his A as an everyday car at least as late as the early 90's. He used windshield washer solvent as antifreeze. Also used as an antifreeze has been salt water. A friend in Idaho bought a Winton that had salt water antifreeze left sitting in it for years.
The salt water prevented freeze up but over the years of storage, it ate holes through the cylinder walls. Also used as an antifreeze has been straight kerosene. No-freeze windshield washer solvent can foam up in the cooling system and over heat it. I presently use RV antifreeze for our Stanley steamers for winter storage.
Works well but like it seems it is a little hard to get a quick steam up for winter use while using the RV antifreeze. Attached Images Stanleys at home small file. I don't know what truth there is to this but I read that Ethylene glycol was designed for use in pressurized systems and that Propylene glycol works better in unpressurized systems beacuse it's not as prone to boil over. I run prestone Low Tox in my Town Sedan it's Propylene glycol you have to use the litmus paper test strips to test the mixture.
These early water cooling systems were also open, which allowed the alcohol to evaporate over time. Charles Adolph Wurtz first synthesized ethylene glycol in The next step in the history of antifreeze was actually taken many years earlier. A substance called ethylene glycol was first synthesized in by French chemist Charles-Adolphe Wurtz. However, very little was done with the substance until the 20th century. It was first produced commercially in , but at that time is was primarily in the manufacture of dynamite.
In addition to being an effective substitute for glycerol in the manufacture of high explosives, ethylene glycol also turned out to have a number of characteristics that made it an ideal antifreeze.
In addition to mixing readily with water in any proportion, it has a lower freezing point than water and a higher boiling point. Ethylene glycol was first used as an automotive antifreeze in , and it saw widespread use in military applications during World War II.
After the war, it became the dominant chemical antifreeze for the remainder of the 20th century. Other chemicals, such as propylene glycol and organic acid technology OAT , have started gaining in popularity, but ethylene glycol is still widely used. Ethylene oxide is mixed with water in a series of process steps to produce ethylene glycol.
Dye formulated specifically for automotive fluids is mixed with the ethylene glycol to give it the appropriate color for use in vehicles.
