What are the three components of coolants?

Coolants are usually made of three key components: water, glycol, and an additive, usually an inhibitor package.

What is the main ingredient of coolant?

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 chemicals are in coolant?

Antifreeze typically contains ethylene glycol, methanol, and propylene glycol. Although the chemicals in antifreeze are relatively nontoxic, the body can metabolize them into highly toxic alcohol byproducts.

What is fully formulated coolant?

Fully formulated coolants contain silicate and other inorganic additives along with supplemental coolant additives (SCAs) to provide engine and cooling system protection. They offer a stabilized, low-silicate formula that helps reduce deposits and the risks of hard water scale.

What is phosphate in coolant?

A phosphate inhibitor such as Dipotassium Phosphate (DKP) is included in many antifreeze formulas to provide several important functions that help reduce automotive cooling system damage.

What are coolant additives?

Supplemental coolant additives (SCA’s) are a chemical package added to coolant either as a liquid, powder or charge inside a filter to fortify the coolant’s anti-corrosive and other desirable properties. Note: OAT extended life coolant does not require SCA’s but should always be topped up with OAT Premix.

Which is used as antifreeze agent?

ethylene glycol
An alcohol used as antifreeze compound is ethylene glycol.

What is OAT in coolant?

An organic additive technology (OAT) coolant contains only organic corrosion inhibitors such as carboxylates and triazole. The carboxylate acid inhibitors used in OAT coolants have very low depletion rates.

What is perfect pH level for engine coolant?

between 8 and 7
First of all, pH (hydrogen potential) measures the acidity or basicity of a solution. For example, for coolant, it should be between 8 and 7. In this regard, it is important to check the pH of the coolant regularly. As a result, corrosion usually occurs in an engine when the coolant pH value is below 7.

How is 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).

What is Type A coolant?

TYPE A Coolants Type “A” has an Anti-Freeze Anti-Boil component such as Ethylene Glycol or Propylene Glycol that raises the boiling point of the water and lowers the freezing point.

What is the mixture of coolant?

The coolant is a mixture of tap-water and anti-freezing compound (glycol/ethanol) mixed with various additives (bitter substance, silicate, antioxidant agents, foam inhibitors) and colored. Bitter substances are used to prevent the coolant from being drunk inadvertently.

What is IAT and OAT in coolant?

These abbreviations refer to the technology used in the corrosion protection component of a coolant. IAT is Inorganic Additive Technology (often termed Conventional Technology), OAT is Organic Additive Technology, and HAT is Hybrid Additive Technology.

What is B type coolant?

Type B coolants contain only inhibitors for rust, corrosion & cavitation. They DO NOT contain any Anti-Freeze/Anti-Boil emulsions. Type B coolants will keep your cooling system from rusting and deteriorating.
