Audi A7 is a top-of-the-line luxury car that demands top-notch care when it comes to maintenance. The car is equipped with a high-performance engine that requires regular servicing to function efficiently. One of the essential maintenance tasks is to check and replace the antifreeze coolant. But which 2017 Audi A7 antifreeze coolant should you use? In this article, we will explore the different types of antifreeze coolants compatible with the 2017 Audi A7 and help you make an informed decision.
Types of Antifreeze Coolants
Antifreeze coolant is a liquid solution that prevents the engine from overheating by absorbing heat and transferring it to the radiator. It also prevents the coolant from freezing during winter months. Antifreeze coolants are primarily classified based on their chemical composition:
1. Inorganic Acid Technology (IAT)
IAT is the most traditional type of antifreeze coolant and consists of a mix of ethylene glycol and water. It also contains inorganic additives such as silicates, borates, and phosphates that provide corrosion protection to the engine. IAT coolant is typically green or yellow in color and has a lifespan of around two years or 30,000 miles.
2. Organic Acid Technology (OAT)
OAT coolant is a newer type of antifreeze coolant that uses organic acid additives such as sebacate, 2-ethylhexanoic acid, and benzoate instead of inorganic additives. OAT coolants are typically red or orange in color and have a lifespan of around five years or 100,000 miles. OAT coolants are also more environmentally friendly than IAT coolants as they do not contain heavy metals.
Which Antifreeze Coolant should you use for your 2017 Audi A7?
The 2017 Audi A7 comes equipped with a high-performance engine that requires a specific type of antifreeze coolant. Audi recommends using G13 coolant, which is a type of OAT coolant specifically designed for Audi vehicles. G13 coolant is available in different colors, including purple, pink, and red, and has a lifespan of around five years or 100,000 miles.
It is essential to note that using the wrong type of coolant can damage your engine and lead to costly repairs. Therefore, it is crucial to use the recommended coolant for your 2017 Audi A7.
How to Check and Replace the Antifreeze Coolant in your 2017 Audi A7
Checking and replacing the antifreeze coolant in your 2017 Audi A7 is a simple task that you can perform yourself. Here's how:
Step 1: Locate the Coolant Reservoir
The coolant reservoir is usually located near the radiator and has two marks indicating the minimum and maximum levels of coolant. Make sure the engine is cool before checking the coolant level.
Step 2: Check the Coolant Level
Check the coolant level by looking at the marks on the reservoir. If the level is below the minimum mark, add the recommended coolant until it reaches the maximum mark.
Step 3: Replace the Coolant
If the coolant is dirty or has exceeded its lifespan, it's time to replace it. Here's how:
- Drain the old coolant by opening the drain valve located at the bottom of the radiator.
- Flush the system by adding water and running the engine for a few minutes.
- Drain the water and add the recommended coolant until it reaches the maximum mark on the reservoir.
Conclusion
Choosing the right antifreeze coolant for your 2017 Audi A7 is crucial to keep your engine running smoothly. Using the recommended G13 coolant is essential to prevent damage to your engine and costly repairs. Checking and replacing the coolant is a simple task that you can perform yourself, provided you follow the correct procedures.
