How is radiator coolant made?

Most antifreeze is made by mixing distilled water with additives and a base product, usually MEG (mono ethylene glycol) or MPG (mono propylene glycol).

How can I make my own radiator coolant?

What is glycol for coolant made from?

Ethylene glycol is produced through the hydrolysis of ethylene oxide. Ethylene (ethene) is a colorless gas produced by the petrochemical industry. Ethylene oxide is mixed with water in a series of process steps to produce ethylene glycol.

What chemicals are in engine coolant?

Antifreeze can be made using any of these four main agents mixed with water: methanol, glycerol, ethylene glycol and propylene glycol.

Why is coolant mixed with water?

Antifreeze is mixed in equal parts with water to create a coolant solution that provides both freezing and boilover protection compared to straight water. Water is an efficient conductor of heat, which is good for cooling the engine and transferring heat to the radiator and heater core.

Where is antifreeze made?

Antifreeze Manufacture

Like all chemical compounds, antifreeze is manufactured in factories. Ethylene glycol is produced by chemically bonding four carbon atoms, six hydrogen atoms and two oxygen atoms. There are over fifteen variations of antifreeze. Most use glycol, but additives vary.

What is the difference between polyethylene glycol and ethylene glycol?

Ethylene glycol is a syrupy liquid at room temperature whereas polyethylene glycol is a solid material. The main difference between ethylene glycol and polyethylene glycol is that ethylene glycol has a fixed value for molecular weight whereas polyethylene glycol has no fixed value for molecular weight.

How toxic is polyethylene glycol?

Polyethylene Glycol Toxicity Symptoms

While it's well-known among the medical community that PEG can trigger an allergy, cause digestive upset, or lead to electrolyte imbalances, there have been more and more reports of neurological symptoms associated with polyethylene glycol.

What is green antifreeze?

Green antifreeze is made with special tweaks to the formula specifically to help prevent the corrosion of metals in a vehicle's cooling system. That older formula is typically meant for vehicles made before the year 2000, which were built with more steel and copper components than modern vehicles.

What can I substitute for coolant?

Water by itself can't do the job of antifreeze due to its lack of boiling and freezing point range and its inability to protect your vehicle's engine. Plus, it doesn't absorb heat as effectively. In the case of an absolute emergency, you can use water in your coolant rank.

What is the chemical formula for antifreeze?

Ethylene glycol (IUPAC name: ethane-1,2-diol) is an organic compound (a vicinal diol) with the formula (CH ₂OH) ₂. It is mainly used for two purposes, as a raw material in the manufacture of polyester fibers and for antifreeze formulations.

What antifreeze has ethylene glycol?

Havoline® Conventional Antifreeze/Coolants are low-silicate, ethylene glycol-based multi-purpose coolants, available as concentrates or 50/50 pre-diluted products. They are for use in automotive engines where silicates are needed and with supplemental coolant additives (SCAs) addition in heavy-duty diesel engines.

What is red antifreeze?

Red. If you have a red coolant in your cooling system, you have an Extended Life Coolant. This coolant is recommended for use in Toyota, Scion, and Lexus. It can be used in any engine requiring an OAT engine coolant. Red coolant offers 150k miles of protection.

What is orange antifreeze for?

Orange antifreeze also helps to protect against corrosion and wear, but it's not meant for vehicles made with a lot of metal. Instead, it is used on newer models that are made from nylon and aluminum. Inside the orange coolant are carboxylates, which work to reduce corrosion.

What is blue antifreeze for?

Antifreeze Blue is a full concentrate which meets BS6580 and contains the same pure ethylene glycol and anti-corrosive additives as the Red. Its application is for protection for up to a maximum of 2 years.

What's the difference between propylene glycol and polyethylene glycol?

Propylene glycol is a viscous, colorless liquid, having the chemical formula CH3CH(OH)CH2OH. The key difference between polyethylene glycol and propylene glycol is that polyethylene glycol is a polymer material, whereas propylene glycol is a single molecular compound that can be named a diol.

What is the brand name for polyethylene glycol?

Commonly used brand names of PEG 3350 available in the United States and Canada are MiraLax, GlycoLax, Lax-A-Day and RestoraLAX. 2. How does PEG 3350 work in the treatment of constipation? PEG 3350 helps constipation by holding more water in the bowel, making stool softer and easier to pass.

Is propylene glycol banned in Europe?

Propylene glycol is a substance commonly used as a food additive or ingredient in many cosmetic and hygiene products. The US and European food authorities have declared it as generally safe for use in foods.

Is polyethylene glycol in radiator fluid?

Polyethylene glycol (PEG) is a polyether compound that has a variety of uses and appearances depending on its molecular weight. Polyethylene Glycol is made by polymerising ethylene glycol, the main ingredient in antifreeze solutions, and has a strong presence in the medical industry.

What color is ethylene glycol coolant?

The color of healthy engine coolant is green (for ethylene glycol) or orange (for Dexcool). A rusty color indicates that the rust inhibitor in the coolant has broken down and it can no longer control rust and scale buildup.

What Colour is propylene glycol antifreeze?

Green Antifreeze

IAT is a mixture of various compounds such as phosphates and silicones, with either propylene glycol or ethylene glycol.

How is ethylene glycol made?

Ethylene glycol is normally produced from ethylene which is produced from fossil resources rather than biomass. However, ethylene glycol can be produced from biomass. Ethylene can be produced from sugars via microorganisms like Pseudomonas syringae and Penicillium digitatum.

Is coolant and antifreeze the same?

Engine coolant, also known as antifreeze, is mixed with water to keep the radiator from freezing in extreme cold and overheating in extreme heat. There are many different types of coolant, so it's important to know what variety is right for your car or truck.

Why is my coolant Brown?

Coolant that is still doing its job to protect your engine can be any variety of colors from green to red to orange, but the key is that it will be translucent. When it's past its prime, it will become a brownish color and more opaque. If it's in really bad shape, it will be a sludgy brown.

What is pink antifreeze used for?

Our specially designed formula for Audi ^® 1997-2007, Volkswagen ^® 1997-2008, Porsche ^® 1999-2009, and Jaguar ^® 1999 and newer. This technology regulates your engine's temperature, prevents freezing and protects the engine from corrosion.
