Engine coolants are known for maintaining an optional temperature of the car, thus ensuring its smooth and efficient operation. This fluid is designed to absorb and disperse heat generated during the combustion process as a result it helps prevent the engine from overheating and sustaining damage. Also known as antifreeze, engine coolants offer protection against freezing in cold temperatures and corrosion. Thus, it is important to understand the importance of engine coolants. 

What is an engine coolant?

Engine coolant is a mixture of water and chemicals, such as ethylene glycol or propylene glycol along with additives that helps in enhancing the performance of the car. By absorbing and transferring the heat away from the engine, engine coolants also help prevent the warping or seizing of the engine. Additionally, engine coolant is a crucial component of a vehicle’s cooling system, playing a significant role in preserving the engine’s health and lifespan.

Why do car engines need engine coolant?

  1. Engine coolants help maintain the optimal operating temperature of the engine.
  2. It prevents freezing and boiling of the engine’s cooling system. 
  3. It serves as a lubricant for the water pump and certain other components within the cooling system.
  4. The engine coolants are equipped with corrosion inhibitors that help protect the engine’s internal components from rust and corrosion. 

Which coolant should one use?

The type of engine coolant you want to pick for the car depends on the make, model, and year of your car. One must refer to the manufacturer’s guidelines and consult your vehicle’s owner’s manual to pick the engine coolant.

There are two types of coolants:

  1. Ethylene-glycol-based coolant: Ethylene-glycol-based coolant is the most common type of coolant found in majority of the cars. They are highly efficient in transferring heat and providing freeze protection. Moreover, these coolants have a wide temperature range thus they can withstand extreme temperatures without freezing or causing damage to the cooling system. Ethylene-glycol-based coolants also have heat dissipation properties that prevent engine overheating.
  2. Propylene glycol-based coolants: Propylene glycol-based coolants are more environmentally friendly and are less toxic in nature. They are especially used when low toxicity or environmental concerns are a priority. 

Both ethylene glycol-based and propylene glycol-based coolants offer their own set of benefits and are suitable for various scenarios. The decision between the two depends on factors like environmental concerns, manufacturer guidelines, and specific application needs. To ensure the correct coolant type for your vehicle, it is recommended to refer to the owner’s manual or seek professional advice. By doing so, you can make an informed choice and select the most appropriate coolant for your vehicle’s requirements.

When To Check the Engine Coolant Level?

To maintain your vehicle’s cooling system, it is recommended to check the coolant level regularly, ideally once a month or before long trips. Additionally, it’s important to inspect the coolant level if you notice signs of overheating or coolant leakage. By keeping a vigilant eye on the coolant level, you can detect potential issues early and take necessary steps to prevent engine damage. Remember to check the coolant level when the engine is cool to avoid any risk of burns or injuries. By proactively monitoring the coolant level, you can ensure proper engine cooling and reduce the risk of overheating and related problems.

How to check and add coolant to your car?

To check and add coolant to your car, here are the steps to follow:

  • Ensure the engine is cool: It’s important to check the coolant level when the engine has had time to cool down, reducing the risk of burns or injuries.
  • Locate the coolant reservoir: Open the hood of your car and find the coolant reservoir. This is usually a transparent plastic tank labeled with “coolant” or “antifreeze.”
  • Check the coolant level: Examine the side of the reservoir to identify the minimum and maximum marks. The coolant level should be within this range. If it falls below the minimum mark, it’s necessary to add more coolant.
  • Prepare the coolant mixture: Review your vehicle’s owner’s manual or the coolant product instructions to determine the appropriate coolant type. Some coolants come premixed with water, while others require you to mix them. If mixing is needed, follow the recommended coolant-to-water ratio.
  • Add coolant: If the coolant level is low, cautiously remove the cap from the coolant reservoir. Pour the coolant into the reservoir gradually, ensuring it reaches a level between the minimum and maximum marks. Avoid overfilling.
  • Replace the cap: Once you have finished adding the coolant, securely tighten the cap on the coolant reservoir.
  • Check for leaks: After adding coolant, inspect the area around the reservoir and the ground beneath your car for any signs of coolant leakage. If you observe any leaks, it’s advisable to have your vehicle examined by a professional mechanic.

How long can one run a car without engine coolant?

Running an engine without coolant should be avoided as it can result in severe damage. Coolant plays a crucial role in regulating the engine’s temperature and preventing overheating. Without coolant, the engine can quickly reach high temperatures, causing the metal components to expand, warp, or seize.

The duration an engine can run without coolant depends on factors like outside temperature, engine load, and cooling system condition. However, it is generally not recommended to run an engine without coolant for more than a brief period.

If the coolant is depleted or there is a leak, it is important to shut off the engine immediately and allow it to cool down. Continuing to run the engine without coolant can lead to irreversible damage, including blown head gaskets, damaged cylinder heads, or a seized engine.

To ensure the engine’s proper functioning and longevity, it is essential to regularly check the coolant level, inspect for leaks, and promptly address any cooling system issues. If you experience coolant loss or car overheating problems, it is advisable to have a qualified mechanic inspect your vehicle and address the underlying cause.
