Introduction to the Volkswagen Atlas and Its Cooling System
The Volkswagen Atlas is a mid-size SUV that was first introduced in 2017. It is designed to provide a spacious and comfortable ride for drivers and passengers alike. However, like any other vehicle, the Atlas requires regular maintenance to ensure its longevity and performance. One of the critical components of the vehicle’s maintenance is the cooling system, which plays a vital role in preventing overheating and damage to the engine.
The Importance of Coolant in the Volkswagen Atlas
Coolant, also known as antifreeze, is a liquid that is used in the cooling system of the Volkswagen Atlas to prevent the engine from overheating. It is a mixture of water and a chemical called ethylene glycol or propylene glycol, which has a low freezing point and a high boiling point. This allows the coolant to absorb and dissipate heat from the engine, keeping it at a safe operating temperature.
The coolant system in the Volkswagen Atlas is designed to circulate the coolant through the engine, radiator, and other components to regulate the temperature. The coolant is pumped through the engine block, cylinder head, and radiator, where it absorbs heat from the engine and dissipates it into the air. The coolant then returns to the engine, where it is cooled by the radiator and the fan.
Types of Coolant Used in the Volkswagen Atlas
The Volkswagen Atlas uses a type of coolant called long-life coolant, which is designed to last for the lifetime of the vehicle. This type of coolant is a mixture of water and ethylene glycol or propylene glycol, and it has a high boiling point and a low freezing point. It is also formulated to resist corrosion and degradation over time, which helps to extend the life of the cooling system.
There are two types of long-life coolant used in the Volkswagen Atlas: type A and type B. Type A coolant is a 50/50 mixture of water and ethylene glycol, while type B coolant is a 60/40 mixture of water and propylene glycol. The type of coolant used depends on the engine type and the climate in which the vehicle is operated.
How to Check the Coolant Level in the Volkswagen Atlas
Checking the coolant level in the Volkswagen Atlas is a simple process that requires a few basic tools. You will need a 50/50 mixture of water and ethylene glycol or propylene glycol, a funnel, and a radiator cap.
To check the coolant level, follow these steps:
- Make sure the engine is cold and the vehicle is parked on a level surface.
- Locate the radiator cap, which is usually located on the driver’s side of the engine compartment.
- Remove the radiator cap by turning it counterclockwise.
- Check the coolant level by looking at the side of the radiator. The level should be between the minimum and maximum marks on the side of the radiator.
- If the level is low, add a 50/50 mixture of water and ethylene glycol or propylene glycol to the radiator until the level reaches the minimum mark.
- Replace the radiator cap and start the engine.
- Let the engine run for a few minutes to circulate the coolant.
- Check the coolant level again to make sure it is at the correct level.
Common Problems with the Cooling System in the Volkswagen Atlas
Like any other vehicle, the Volkswagen Atlas can experience problems with its cooling system. Some common problems include:
Leaks in the cooling system
Leaks can occur in the radiator, hoses, or water pump, which can cause the engine to overheat. If you notice a leak in the cooling system, it is essential to have it repaired as soon as possible to prevent damage to the engine.
What to Do If You Notice a Leak in the Cooling System
If you notice a leak in the cooling system, follow these steps:
- Turn off the engine and let it cool down.
- Locate the source of the leak and mark it with a piece of tape or a marker.
- Replace the radiator cap and start the engine.
- Let the engine run for a few minutes to circulate the coolant.
- Check the leak again to make sure it is not getting worse.
- Have the leak repaired by a qualified mechanic as soon as possible.

Frequently Asked Questions
What is the recommended coolant for a VW Atlas?
The recommended coolant for a VW Atlas is a 50/50 mix of Volkswagen Genuine Long Life Coolant (LLC) or a compatible mixture of ethylene glycol and water. This coolant meets the requirements of the VW Atlas’s engine and cooling system. It is essential to use a coolant that meets the VW Atlas’s specifications to ensure optimal performance and longevity of the engine. Using a non-compatible coolant can lead to corrosion, overheating, and engine damage. Always check the owner’s manual or consult with a VW dealership or certified mechanic for specific recommendations.
What is the difference between Long Life Coolant and regular coolant?
Long Life Coolant (LLC) is a type of coolant designed for modern engines, including the VW Atlas. It is formulated to provide longer engine life, improved corrosion protection, and better performance in extreme temperatures. LLC has a higher pH level than regular coolant, which helps to prevent corrosion and scaling in the cooling system. It also has a lower toxicity and is more environmentally friendly than regular coolant. Regular coolant, on the other hand, may need to be changed more frequently and may not provide the same level of protection as LLC.
Why should I use a 50/50 mix of coolant and water?
A 50/50 mix of coolant and water is recommended for the VW Atlas because it provides the optimal balance of corrosion protection and freezing protection. The coolant helps to prevent corrosion and scaling in the cooling system, while the water helps to dilute the coolant and prevent it from becoming too concentrated. A 50/50 mix also helps to maintain the pH level of the coolant, which is essential for preventing corrosion and damage to the engine. Using a mixture that is too concentrated or too diluted can lead to problems with the cooling system and engine damage.
How do I check the coolant level in my VW Atlas?
To check the coolant level in your VW Atlas, you will need to locate the coolant reservoir under the hood. The reservoir is a transparent plastic container that holds the coolant. Check the level by looking at the side of the reservoir. The level should be between the “MIN” and “MAX” marks. If the level is below the “MIN” mark, you will need to add more coolant. Always use a 50/50 mix of coolant and water and follow the manufacturer’s instructions for adding coolant.
What happens if I use the wrong coolant in my VW Atlas?
Using the wrong coolant in your VW Atlas can lead to serious problems with the engine and cooling system. If you use a coolant that is too concentrated or too diluted, it can cause corrosion and scaling in the cooling system, which can lead to engine damage and overheating. In extreme cases, using the wrong coolant can cause the engine to seize or fail, which can be costly to repair. Always use a coolant that meets the specifications of the VW Atlas and follow the manufacturer’s instructions for adding coolant.
How often should I change the coolant in my VW Atlas?
The recommended interval for changing the coolant in your VW Atlas varies depending on the driving conditions and the age of the vehicle. Generally, it is recommended to change the coolant every 30,000 to 50,000 miles or as specified in the owner’s manual. However, if you drive in extreme temperatures, tow a trailer, or drive in stop-and-go traffic, you may need to change the coolant more frequently. Always check the owner’s manual or consult with a VW dealership or certified mechanic for specific recommendations. (See: Put Coolant Toyota Rav4)
What are the benefits of using a high-quality coolant in my VW Atlas?
Using a high-quality coolant in your VW Atlas provides several benefits, including improved engine performance, reduced corrosion and scaling, and better protection against extreme temperatures. High-quality coolants are also more environmentally friendly and have a lower toxicity than regular coolants.
