When it comes to maintaining the health and longevity of your vehicle, there are many factors to consider. One often-overlooked aspect is the engine coolant, which plays a crucial role in regulating the temperature of your engine. With so many options available, choosing the right colour engine coolant can be a daunting task. In this article, we will delve into the world of engine coolants, exploring the different colours, their properties, and what you need to know to make an informed decision.
What is Engine Coolant?
Engine coolant is a liquid solution designed to regulate the temperature of your engine. It works by absorbing and transferring heat from the engine to the radiator, where it is dissipated. Engine coolants are typically made up of a combination of water, antifreeze, and other additives that help to prevent corrosion and scale buildup.
The Importance of Engine Coolant
Engine coolant is essential for maintaining the health of your engine. Without it, your engine would quickly overheat, leading to costly repairs and potentially even engine failure. Engine coolants also help to prevent corrosion and scale buildup, which can cause damage to your engine and other components.

What Colour Engine Coolant Do I Need?
The answer to this question depends on a variety of factors, including the type of vehicle you own, the climate you live in, and your personal preferences. In this section, we will explore the different colours of engine coolant and what they are used for.
Green Engine Coolant
Green engine coolant is a type of ethylene glycol-based coolant that is designed for use in traditional engines. It is typically used in vehicles that are driven in moderate temperatures, and is not recommended for use in extreme cold or hot temperatures.
| Properties | Green Engine Coolant |
|---|---|
| Antifreeze Type | Ethylene Glycol |
| Freezing Point | -34°C (-29°F) |
| Boiling Point | 105°C (221°F) |
Yellow Engine Coolant
Yellow engine coolant is a type of propylene glycol-based coolant that is designed for use in vehicles that require a lower freezing point. It is typically used in vehicles that are driven in extreme cold temperatures, and is not recommended for use in traditional engines. (See Also: What Can Cause Oil and Coolant to Mix?

| Properties | Yellow Engine Coolant |
|---|---|
| Antifreeze Type | Propylene Glycol |
| Freezing Point | -50°C (-58°F) |
| Boiling Point | 100°C (212°F) |
Purple Engine Coolant
Purple engine coolant is a type of hybrid coolant that is designed for use in vehicles that require a high level of protection against corrosion and scale buildup. It is typically used in vehicles that are driven in extreme temperatures, and is not recommended for use in traditional engines.
| Properties | Purple Engine Coolant |
|---|---|
| Antifreeze Type | Hybrid (Ethylene Glycol and Propylene Glycol) |
| Freezing Point | -40°C (-40°F) |
| Boiling Point | 105°C (221°F) |
Choosing the Right Engine Coolant
Choosing the right engine coolant for your vehicle can be a daunting task. Here are a few tips to help you make an informed decision:
Consider the Climate
If you live in an area with extreme cold temperatures, you will want to choose an engine coolant with a lower freezing point. If you live in an area with extreme hot temperatures, you will want to choose an engine coolant with a higher boiling point.
Consider the Type of Vehicle
If you own a traditional engine, you will want to choose an engine coolant that is designed for use in traditional engines. If you own a hybrid or electric vehicle, you will want to choose an engine coolant that is designed for use in these types of vehicles.
Consider the Manufacturer’s Recommendations
Always check your vehicle’s manufacturer recommendations for the type of engine coolant to use. They may have specific recommendations based on the type of engine and the climate you live in. (See Also: How to Replace Coolant Reservoir? A Step-by-Step Guide)

Frequently Asked Questions (FAQs)
Q: What is the difference between green and yellow engine coolant?
A: Green engine coolant is a type of ethylene glycol-based coolant that is designed for use in traditional engines. Yellow engine coolant is a type of propylene glycol-based coolant that is designed for use in vehicles that require a lower freezing point. The main difference between the two is the type of antifreeze used and the freezing point of the coolant.
Q: Can I use purple engine coolant in my traditional engine?
A: No, purple engine coolant is a type of hybrid coolant that is designed for use in vehicles that require a high level of protection against corrosion and scale buildup. It is not recommended for use in traditional engines.
Q: How often should I change my engine coolant?
A: The frequency of changing your engine coolant depends on the type of coolant used and the manufacturer’s recommendations. Typically, engine coolant should be changed every 30,000 to 50,000 miles or as recommended by the manufacturer. (See Also: Do I Need To Flush My Radiator Before Adding Coolant? – Find Out Now)
Q: Can I mix different types of engine coolant?
A: No, it is not recommended to mix different types of engine coolant. Each type of coolant has its own unique properties and mixing them can cause problems with the cooling system. Always use the same type of coolant recommended by the manufacturer.
Q: What are the signs of low engine coolant levels?
A: The signs of low engine coolant levels include a temperature gauge that is higher than normal, a sweet or pungent smell coming from the engine, and a decrease in engine performance. If you notice any of these signs, it is recommended to check the coolant level and top it off as needed.
