Introduction to Coolant Colors
When it comes to identifying burning coolant, color plays a crucial role. Different types of coolant display various colors when they are burning, and it is essential to understand these colors to diagnose potential issues in your engine. In this section, we will delve into the world of coolant colors, exploring the different types, their characteristics, and how to identify them.
Green Coolant: Ethylene Glycol (EG) vs. Propylene Glycol (PG)
Ethylene glycol (EG) and propylene glycol (PG) are two common types of coolants used in vehicles. Both coolants display distinct colors when burning, making it easier to diagnose potential issues.
–
EG Coolant: Amber to Dark Brown
EG coolants typically display an amber to dark brown color when burning. This coloration is due to the presence of phenol and other additives in the coolant. When EG coolant burns, it produces a sweet, syrupy smell, which can be a sign of a serious issue.
–
PG Coolant: Light Brown to Yellow
PG coolants, on the other hand, display a light brown to yellow color when burning. This coloration is due to the presence of phenol and other additives in the coolant. When PG coolant burns, it produces a slightly sweet, but more acrid smell than EG coolant.
Other Coolant Colors: OAT, HOAT, and IAT Coolants
In addition to EG and PG coolants, there are other types of coolants available in the market, such as OAT (Organic Acid Technology), HOAT (Hybrid Organic Acid Technology), and IAT (Inorganic Acid Technology) coolants. Each of these coolants displays distinct colors when burning, making it essential to understand their characteristics.
–
OAT Coolant: Pale Yellow to Light Brown
OAT coolants typically display a pale yellow to light brown color when burning. This coloration is due to the presence of organic acids and other additives in the coolant. When OAT coolant burns, it produces a sweet, slightly acrid smell.
–
HOAT Coolant: Light Brown to Dark Brown
HOAT coolants display a light brown to dark brown color when burning. This coloration is due to the presence of hybrid organic acids and other additives in the coolant. When HOAT coolant burns, it produces a sweet, slightly acrid smell.
–
IAT Coolant: Pale Yellow to Light Brown
IAT coolants typically display a pale yellow to light brown color when burning. This coloration is due to the presence of inorganic acids and other additives in the coolant. When IAT coolant burns, it produces a sweet, slightly acrid smell.
