When it comes to keeping your car running smoothly, the engine is the heart of the vehicle, and maintaining its health is important for optimum performance. One of the most important things that make your engine run without overheating is engine coolant. Though often overlooked, coolant is vital in controlling your car engine temperature. In this article, we will discuss what engine coolant is, why it is needed, the causes and signs of low coolant levels, and how you can maintain your coolant system.

What Is Engine Coolant and What Does It Do?

Engine coolant, commonly called car coolant, is a special liquid found in your car's cooling system. This fluid absorbs and transfers heat coming from your car's engine. The fluid controls the temperature of your car engine by preventing it from overheating during hot weather and freezing during cold weather.

Coolant is typically a mixture of water and antifreeze (ethylene glycol or propylene glycol). The antifreeze prevents the coolant from freezing in cold weather and helps maintain a stable temperature in hot weather. The mixture circulates through the engine and the radiator, absorbing heat from the engine and releasing it through the radiator, where it is cooled by air.

Engine coolant is critical for:

Preventing Overheating: Overheating can damage engine components, so maintaining the correct coolant levels ensures the engine stays cool and performs efficiently.

Preventing Freezing: Antifreeze within the coolant prevents freezing in cold temperatures, ensuring smooth operation in winter conditions.

Preventing Corrosion: Coolant protects the engine’s internal components, like the radiator and hoses, from corrosion, which can degrade the performance of your cooling system.

Causes of Low Coolant Levels

Low coolant levels can occur for a variety of reasons, and it's important to address this issue promptly to avoid engine damage. Here are some common causes:

• Leaks in the Cooling System: Leaks in the radiator, hoses, water pump, or the engine block can cause coolant loss.
• Damaged Radiator Cap: A broken or loose radiator cap can cause the coolant to evaporate, thus causing low levels.
• Faulty Thermostat: A stuck thermostat can cause the coolant to stay longer in the engine and not circulate properly.
• Worn-Out Water Pump: A failing water pump can cause inadequate circulation of coolant, leading to low levels.
• Evaporation: Coolant can naturally evaporate over time, especially if not properly maintained.

Signs of Low Coolant Levels

Knowing the signs of low coolant levels is very important to prevent further damage to your engine. Some of the common symptoms include:

• Engine Overheating: If your car's temperature gauge rises into the red zone, it might be a sign that the coolant level is too low.
• Coolant Leaks: A visible puddle of coolant under your car is a sure sign that your coolant system is leaking.
• Engine Performance Problems: A low coolant level can result in the engine misfires, rough idling, or poor acceleration.
• Heater Is Not Working Properly: If your heater is not blowing warm air inside your car, it might mean that your coolant levels are low.
• Dashboard Warning Lights: The latest car models contain sensors that will activate a warning light on your dashboard in case coolant levels get low.

Dangers of Driving with Low Coolant

Driving with low coolant levels can be very damaging to your engine and overall car health. This is why:

• Overheating: The most obvious risk of driving with low coolant levels is engine overheating. If the coolant is low, then your engine can't release heat properly. Overheating may cause your engine parts to warp or seize.
• Expensive Repairs: Driving the vehicle for an extended period with low coolant can result in costly damage such as a blown head gasket, cracked engine block, or damaged radiator. Repairs can be so costly that replacement of the engine is needed.
• Fuel Economy: If your engine is overheating, it will lower your car's fuel economy since the engine needs to work extra hard to cool itself instead of producing power.

What to Do if You Suspect Low Coolant Levels?

If you suspect that your car's coolant levels are low, here's what you should do:

• Check Engine Coolant Levels: Check the engine coolant reservoir when the engine is cool, if the level of the coolant is below the "min" mark.
• Look for Leaks: Look for visible engine coolant puddles under the car or in the engine bay and fix the leak.
• Topping Up: Top up the engine coolant by adding a mixture of antifreeze and water. Be sure to use the correct type of engine coolant for your car model.
• Seek Professional Help: If you are unsure about how to handle the situation or the level keeps falling, you will need to seek professional help at a mechanic or trusted service center.

Preventative Tips for Maintaining Proper Coolant Levels

To prevent low coolant levels and maintain your engine's health, follow these tips:

• Regularly Check Coolant Levels: Periodically check the car coolant reservoir to ensure it’s at the recommended level.
• Use the Right Car Coolant: Always use the recommended type of coolant for your car. Check the owner’s manual for specific guidelines.
• Inspect for Leaks: Check the hoses, radiator, and water pump for any signs of leaks or cracks. Leaks should be fixed immediately.
• Flush the Cooling System: Over time, car coolant can degrade and become contaminated. Flushing the radiator and replacing old car coolant is necessary to keep your engine cool.
• Regular Maintenance: Ensure that the radiator, thermostat, and water pump are functioning correctly by scheduling regular maintenance with a professional mechanic.
