Glycol

The primary function of ethylene glycol in the coolant is to offer anti-freeze anti-boil protection. Water is an active heat transfer fluid by itself. However, it has a limited operating temperature range. When combined with Glycol, the formulation offers a lower freezing point & a higher boiling point than either fluid used on their own.

 

Types of Coolants

Coolants are classified as either Type A or Type B depending on the level of glycol they contain.

 

Type A Coolants

• Contain above 20% glycol content

• Offer anti-freeze anti-boil protection

• Nearly all new car manufacturers will recommend a Type A product

 

Type B Coolants

• Contain below 20% glycol content

• Offer minimal or no anti-freeze anti-boil protection

• Typically they are referred to as corrosion inhibitors

 

Organic Vs Conventional Coolants

Conventional style coolants are created using older technology but have a solid performance history. This traditional type of coolant will have a shorter lifespan than organic & is suited to earlier model vehicles.

 

Organic coolants are manufactured using a new process referred to as Organic Acid Technology (OAT). This process provides the ability to along lifespan due to low chemical depletion rate.

 

Note: Conventional & organic style coolants do not mix well together.

 

Corrosion

There are many types of corrosion that can occur in a cooling system, which is why a coolant with a good quality corrosion inhibitor package is required. Tectaloy coolants all contain an inhibitor package that provides maximum protection against corrosion.
