Composition of a Coolant Coolant is primarily a mixture of de-ionized water, glycol (mainly ethylene glycol or propylene glycol) and chemical additives. It is incumbent to select a coolant according to your requirement. The choice depends on the kind of environment and temperatures the engine is frequently exposed to.

What are Radiator coolant made of?
All automotive coolants are glycol-based. Common coolants consist of a mixture of ethylene glycol with additive packages and some water. Another glycol-based coolant consists of propylene glycol and water. The major difference between the two types is that propylene glycol is less toxic.
What is the main ingredient of coolant?
The main ingredient in the coolant used today is ethylene glycol.
What are the three components of coolants?
Coolants are usually made of three key components: water, glycol, and an additive, usually an inhibitor package. Here are those three components in more detail: Water: Water is one of the most abundant substances on Earth. It's inexpensive, and it is one of the most effective heat exchange mediums around.
What is the difference between engine coolant and radiator coolant?
Well, antifreeze and engine coolant are similar, but not the same. ... Ethylene Glycol prevents coolant liquid freezing within your radiator by lowering its freezing temperature, alongside lubricating the water pump and inhibiting corrosion. Engine coolant is a mixture of antifreeze and water, with a common ratio of 50:50.
What is nitrite coolant?
“Nitrite is a vital component in older conventional fully formulated antifreeze and is used to prevent liner pitting, which occurs when vapor bubbles form in the coolant by the vibration of the liner and implode against the liner, releasing a high-pressure jet of water which causes cavitation, erosion and corrosion of ...
Is polyethylene glycol in antifreeze?
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.
Is alcohol a better coolant than water?
Compared with water, alcohol has a lower heat of evaporation. ... As alcohol evaporates at a much faster rate compared with water due to its lower boiling temperature (82 compared to 100 degrees C), it is able to carry away more heat from the skin.
What is propylene glycol coolant?
Propylene glycol is added to food and beverages to improve taste and texture. It is not antifreeze. It is considered safe to use in the amount present in foods.
What is a phosphate based coolant?
Currently, these green coolants typically use a phosphate/ silicate mix as the main components in their inhibitor system. Conventional inhibitors like silicates and phosphates work by forming a protective blanket that actually insulates the metals from the coolant.
What causes coolant to return to the radiator?
As it cools , it contracts. The atmospheric pressure that is on the coolant that is in the coolant tank forces the coolant that is in the tank to go backward up the overflow and back into the radiator through a one-way check valve that is inside the radiator cap.
What are silicates in coolant?
In newer automotive applications, silicates are needed to protect aluminum engine parts and radiators from corrosion, and are used in virtually all antifreeze mixtures in varying forms and amounts. ... Silicate gel buildup greatly reduces heat transfer from the engine castings to the coolant.
Is it OK to put coolant in the radiator?
On all vehicles that have a reservoir you add it to the reservoir, unless it is totally empty, then you can add it to the radiator directly. Once the radiator is full you will want to finish topping it off through the reservoir. If you just need to add because it is loww, then always use the reservoir.
Can I use water instead of 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.
Can I put water in my radiator instead of coolant?
Can I use water instead of coolant? Using a coolant in your vehicle's radiator is best to prevent overheating. However, you can use water in a pinch if you don't have any. Just be mindful that water boils quicker than coolant, so you'll want to change it out as soon as possible.
What is borate in coolant?
Borate is a pH buffer that: Lowers the freezing point of the coolant. Increases the boiling point of the coolant. Reduces friction and sludge. Prevents corrosion at high temperatures.
What is molybdate in coolant?
A molybdate-free antifreeze composition comprising from 50 to 99 wt. % of a glycol freezing point depressant selected from the group of: alkylene glycols, glycol monoethers, glycerins, and mixtures thereof; 0.1 to 5 wt. ... The antifreeze composition of claim 1, wherein less than 2 wt.
Can you mix nitrite and nitrite free coolant?
A well-formulated nitrite-free OAT can match or exceed the protection of NOAT formulations.” On the maintenance side, Dilley advises users to know the exact coolant in use, saying that, although OAT and NOAT formulations are compatible, mixing the two dilutes the inhibitor package of each.
What is the difference between ethylene glycol and polyethylene glycol antifreeze?
The key difference between ethylene glycol and polyethylene glycol is their chemical structure. Ethylene glycol is a simple linear molecule, whereas polyethylene glycol is a polymeric material. In addition, both of these compounds are commercially very important and used in a number of applications.
What is the brand name for polyethylene glycol?
polyethylene glycol (Miralax, Glycolax): Laxative Side Effects & Dosage.
What's the difference between polyethylene glycol and propylene glycol?
The key difference between polyethylene glycol and propylene glycol is that polyethylene glycol is a polymer, whereas propylene glycol is a single molecular compound that can be named a diol. Polyethylene glycol and propylene glycol are important organic compounds.
