Frequently Asked Questions
What is engine coolant, and what does it do?
Engine coolant, also known as antifreeze, is a liquid that circulates through your vehicle’s engine to regulate its temperature. It absorbs and transfers heat away from the engine, preventing it from overheating or freezing in cold temperatures. Engine coolant also helps to prevent corrosion and wear on engine components by neutralizing acidic substances that can form in the cooling system. Without engine coolant, your engine can suffer from serious damage, including overheating, engine failure, and costly repairs.
What happens if you run out of engine coolant?
If you run out of engine coolant, your engine will begin to overheat, which can cause serious damage to the engine, head gasket, and other components. This can lead to costly repairs, including replacing the engine or head gasket, which can cost upwards of $1,000 to $3,000 or more. In extreme cases, a blown head gasket can cause the engine to seize, requiring a new engine, which can cost $2,000 to $5,000 or more.
How often should I check my engine coolant level?
It’s recommended to check your engine coolant level every month or before long trips. You can find the engine coolant reservoir under the hood of your vehicle, and it’s usually labeled with a picture of a coolant bottle. Make sure to use a coolant tester to ensure the correct mixture of antifreeze and water. If you notice the level is low, top it off with the recommended type of coolant. (See: Get Rid Coolant Near Me)
Can I drive a car with low engine coolant?
It’s not recommended to drive a car with low engine coolant, as it can cause serious damage to the engine. However, if you’re in a situation where you need to drive to a repair shop or a safe location, it’s better to drive carefully and slowly to avoid overheating the engine. But please note that driving with low engine coolant is not a long-term solution and can still cause damage to your engine.
How much does it cost to replace engine coolant?
