What is Coolant for a Car Engine?
Coolant is a vital fluid in your car’s engine. It helps to keep the engine from overheating by absorbing heat and transferring it to the radiator, where it is then dissipated into the atmosphere. Coolant also helps to prevent corrosion and lubricate the water pump.
##
Types of Coolant
There are two main types of coolant:
* **Inorganic coolant (I.A.T.)** is the traditional type of coolant. It is made from a mixture of water and ethylene glycol, and it contains silicates and phosphates to help prevent corrosion. I.A.T. coolant typically has a green or yellow color.
* **Organic acid technology (O.A.T.)** coolant is a newer type of coolant that is more environmentally friendly than I.A.T. coolant. It is made from a mixture of water and organic acids, and it does not contain silicates or phosphates. O.A.T. coolant typically has a red or orange color.

How to Choose the Right Coolant
The type of coolant that you choose for your car will depend on the make and model of your car, as well as the climate in which you live. If you are unsure of what type of coolant to use, consult your owner’s manual or a qualified mechanic.

How to Check Your Coolant Level
It is important to check your coolant level regularly, especially before long trips. To check your coolant level, follow these steps:
1. Allow the engine to cool completely.
2. Open the hood and locate the coolant reservoir.
3. Check the coolant level in the reservoir. The coolant level should be between the “FULL” and “LOW” marks on the reservoir.
4. If the coolant level is low, add a 50/50 mixture of coolant and water to the reservoir until the level reaches the “FULL” mark.

How to Flush Your Coolant
It is recommended to flush your coolant every 30,000 to 50,000 miles or every 2 to 3 years, whichever comes first. To flush your coolant, follow these steps:
1. Allow the engine to cool completely.
2. Open the hood and locate the radiator drain plug.
3. Place a drain pan under the radiator drain plug.
4. Open the radiator drain plug and allow the coolant to drain into the drain pan.
5. Once the coolant has drained, close the radiator drain plug.
6. Fill the radiator with a 50/50 mixture of coolant and water.
7. Start the engine and allow it to run for a few minutes.
8. Check for leaks and add more coolant if necessary.

Coolant Additives
There are a number of coolant additives that can be added to your coolant to improve its performance. These additives can help to:
* Prevent corrosion
* Lubricate the water pump
* Protect against freezing
* Improve heat transfer
If you are considering adding a coolant additive, be sure to consult your owner’s manual or a qualified mechanic first.
