## What is Car Engine Coolant?
Car engine coolant, also known as antifreeze, is a vital fluid that helps to keep your engine running smoothly. It circulates through the engine, absorbing heat from the engine block and cylinder heads and carrying it away to the radiator, where it is released into the atmosphere. Coolant also helps to prevent the engine from freezing in cold weather and from boiling over in hot weather.
What are the different types of car engine coolant?
There are two main types of car engine coolant:
* **Inorganic additive technology (IAT)** coolant is the traditional type of coolant, and it is still used in many older vehicles. IAT coolant contains silicates, which help to protect the metal components of the engine from corrosion. However, silicates can break down over time, and they can leave deposits in the cooling system.
* **Organic acid technology (OAT)** coolant is a newer type of coolant, and it is becoming increasingly popular. OAT coolant contains organic acids, which are less likely to break down than silicates. OAT coolant also provides better protection against corrosion than IAT coolant.
How often should I change my car engine coolant?
The frequency with which you should change your car engine coolant depends on the type of coolant that you are using. IAT coolant should be changed every 2 years or 30,000 miles, whichever comes first. OAT coolant can last longer, and it is typically only necessary to change it every 5 years or 100,000 miles.
What are the signs of a coolant leak?
There are several signs that may indicate a coolant leak, including:
* **Low coolant level:** If you check your coolant level and it is below the “min” mark on the reservoir, it may be a sign of a leak.
* **Overheating engine:** If your engine is overheating, it may be a sign that the coolant is not circulating properly due to a leak.
* **Steam or coolant leaking from the engine:** If you see steam or coolant leaking from the engine, it is a sure sign of a leak.
What should I do if I think I have a coolant leak?
If you think you have a coolant leak, it is important to have it checked out by a mechanic as soon as possible. A coolant leak can lead to serious engine damage if it is not repaired.
How can I prevent coolant leaks?
There are a few things that you can do to help prevent coolant leaks, including:
* **Check your coolant level regularly:** Checking your coolant level regularly can help you to identify and fix small leaks before they become major problems.
* **Flush your cooling system:** Flushing your cooling system every few years can help to remove any sediment or debris that may be blocking the coolant passages and causing leaks.
* **Use high-quality coolant:** Using high-quality coolant that is specifically designed for your vehicle can help to prevent leaks.
Conclusion
Car engine coolant is a vital fluid that helps to keep your engine running smoothly. It is important to check your coolant level regularly and to change it according to the manufacturer’s recommendations. If you think you have a coolant leak, it is important to have it checked out by a mechanic as soon as possible.
