Engine Coolant in Car

What is Engine Coolant?

Engine coolant, also known as antifreeze, is a liquid that is used to cool the engine of a car. It is made up of a mixture of water and ethylene glycol, and it works by absorbing heat from the engine and then dissipating it into the atmosphere.

Why is Engine Coolant Important?

Engine coolant is important because it helps to prevent the engine from overheating. Overheating can cause serious damage to the engine, including warped cylinder heads, blown head gaskets, and even seized pistons.

How to Check Engine Coolant

You should check your engine coolant level regularly, especially before you go on a long trip. To check the coolant level, follow these steps:

1. Park your car on a level surface.
2. Open the hood.
3. Locate the coolant reservoir. It is usually a clear plastic tank with a black cap.
4. Check the coolant level. It should be between the “full” and “low” marks on the reservoir.
5. If the coolant level is low, add more coolant until it reaches the “full” mark.

How to Flush Engine Coolant

You should flush your engine coolant every 30,000 miles or 2 years, whichever comes first. To flush the coolant, follow these steps:

1. Park your car on a level surface.
2. Open the hood.
3. Locate the drain plug on the radiator. It is usually a small bolt located at the bottom of the radiator.
4. Place a drain pan under the radiator.
5. Open the drain plug and allow the coolant to drain out.
6. Once the coolant has drained out, close the drain plug.
7. Fill the radiator with clean water.
8. Start the engine and let it run for a few minutes.
9. Stop the engine and allow the water to cool down.
10. Drain the water out of the radiator.
11. Repeat steps 7-10 until the water runs clear.
12. Fill the radiator with new coolant.

Tips for Maintaining Engine Coolant

Here are a few tips for maintaining your engine coolant:

• Check the coolant level regularly.
• Flush the coolant every 30,000 miles or 2 years, whichever comes first.
• Use a coolant that is specifically designed for your car.
• Avoid using water as a coolant, as it can cause corrosion.
• If you have any questions about engine coolant, consult with a qualified mechanic.
