Coolant color is not just a cosmetic feature; it can provide valuable information about the type of coolant and its compatibility with your vehicle. Each type of coolant typically has a distinct color, such as green for IAT, orange or red for OAT, and yellow or orange for HOAT.
However, some variations and overlaps in color may occur, so it’s important not to rely solely on color when choosing a coolant. Always read the labels on the engine coolant container and cross-reference them with your car manufacturer’s recommendations to ensure you are using the correct coolant for your vehicle.
Mixing Different Types of Coolants
Mixing different types of coolants can lead to reduced performance, decreased corrosion protection, and potential damage to your vehicle’s cooling system. Different coolant types have distinct formulations and additives, which may not be compatible with one another when mixed. This incompatibility can cause the coolant to become less effective in regulating temperature, preventing corrosion, and lubricating the cooling system components.
In some cases, mixing coolants can even cause the formation of harmful deposits or gel-like substances, which can obstruct the flow of coolant and lead to engine overheating or coolant system failure. To avoid these issues, always use the recommended coolant type for your vehicle and avoid mixing different coolant types.
Types of coolants
There are several types of coolants available in the market, each with distinct formulations and properties. The four main types of coolants are:
Inorganic Additive Technology (IAT)
This type of coolant is primarily composed of inorganic corrosion inhibitors and is commonly found in older cars. IAT (inorganic additive technology) coolants typically have a green color and require more frequent replacement due to their shorter lifespan and deteriorating freezing point. Your traditional green coolant is IAT coolant.
Organic Acid Technology (OAT)
OAT coolants use organic acids as their primary corrosion inhibitors, offering longer service intervals than IAT coolants. They are often found in newer vehicles and are available in various colors, including orange, red, and purple.
Hybrid Organic Acid Technology (HOAT)
As the name suggests, HOAT coolants combine the properties of both IAT and OAT organic acid technology) coolants. They offer extended service intervals and improved corrosion protection, making them suitable for a wide range of vehicles. HOAT coolants are typically yellow or orange.
Phosphate-free Organic Additive Technology (P-OAT)
P-OAT coolants are similar to OAT coolants, but they do not contain phosphates. This formulation is designed to meet the requirements of specific European and Asian car manufacturers, which prefer phosphate-free coolants to prevent the formation of deposits in the cooling system. P-OAT coolants can be found in various colors, including blue and pink.
Risks of Using the Wrong Coolant
Using the wrong type of coolant or mixing different coolants can cause significant damage to your vehicle’s cooling system. Incompatible coolants may not provide the necessary corrosion protection, leading to rust and deterioration of cooling system components.
The formation of harmful deposits or gel-like substances can obstruct the flow of coolant, causing poor circulation and reduced cooling efficiency. This damage can lead to leaks, decreased boiling point, and ultimately, the failure of the cooling system, which can be costly to repair. You should schedule a coolant flush as soon as possible to avoid damage to gas or diesel engines.
The primary function of a coolant is to regulate the engine’s temperature by absorbing and dissipating the heat generated during operation. Using an incompatible coolant or one with reduced effectiveness can result in inadequate cooling, causing the engine to overheat.
