How to Check if Car Needs Coolant: Understanding the Basics
Checking if a car needs coolant is an essential task for car owners to ensure their vehicle’s engine runs smoothly and efficiently. Coolant, also known as antifreeze, plays a vital role in regulating engine temperature, preventing overheating, and protecting the engine from corrosion. In this section, we will delve into the basics of coolant, its functions, and how to check if your car needs coolant.
Coolant Functions
Coolant serves several purposes in a car’s engine:
- It helps to regulate engine temperature, preventing overheating, and ensuring that the engine operates within a safe temperature range.
- It protects the engine from corrosion by inhibiting the formation of rust and scale.
- It prevents the engine from freezing in cold temperatures, ensuring that the engine continues to run smoothly even in sub-zero temperatures.
- It helps to maintain the performance and efficiency of the engine by ensuring that the engine oil remains at the optimal temperature.
There are two main types of coolant: ethylene glycol and propylene glycol. Ethylene glycol is the most commonly used coolant and is effective in temperatures as low as -20°C. Propylene glycol, on the other hand, is biodegradable and is often used in newer vehicles.
Signs of Low Coolant
If your car’s coolant level is low, you may notice the following signs:
- Engine overheating: The temperature gauge on your dashboard may start to rise, indicating that the engine is overheating.
- Steam coming from the hood: If the coolant level is low, steam may escape from the hood, indicating that the engine is overheating.
- Leaking coolant: If the coolant level is low, you may notice a leak in the radiator or hoses, causing coolant to leak onto the ground.
- Engine noise: A low coolant level can cause the engine to produce unusual noises, such as a knocking or clunking sound.
How to Check Coolant Levels
To check the coolant level, follow these steps:
- Ensure the engine is turned off and the car is parked on a level surface.
- Locate the coolant reservoir, which is usually a transparent plastic container located near the radiator.
- Check the coolant level by looking at the side of the reservoir. The level should be between the “MIN” and “MAX” marks.
- If the level is below the “MIN” mark, you will need to add coolant to bring the level up to the recommended level.
It is essential to note that the coolant level should be checked when the engine is cold. If the engine is hot, the coolant level may be higher than when the engine is cold.
How to Add Coolant
To add coolant, follow these steps:
- Ensure the engine is turned off and the car is parked on a level surface.
- Locate the coolant reservoir and remove the cap.
- Check the coolant level and add the recommended type and amount of coolant to bring the level up to the recommended level.
- Replace the cap and start the engine to ensure the coolant is circulating properly.
Types of Coolant
There are several types of coolant available, each with its unique characteristics and benefits:
- Conventional coolant: This is the most commonly used coolant and is effective in temperatures as low as -20°C.
- Organic acid technology (OAT) coolant: This type of coolant is biodegradable and is often used in newer vehicles.
- Hybrid organic acid technology (HOAT) coolant: This type of coolant is a combination of OAT and conventional coolant and offers improved performance and protection.
- Long-life coolant: This type of coolant is designed to last longer than conventional coolant and is often used in high-performance vehicles.

Section 4: Checking Coolant Levels and Condition
Checking Coolant Levels
One of the simplest ways to determine if your car needs coolant is to check the coolant level. This is usually done by looking at the coolant reservoir, which is a transparent plastic container located near the radiator. The reservoir is connected to the engine and contains a mixture of water and coolant, which helps to regulate the engine’s temperature.
To check the coolant level, follow these steps:
- Locate the coolant reservoir under the hood of your car.
- Look for the minimum and maximum marks on the side of the reservoir.
- Check the current level of the coolant against these marks.
- If the level is below the minimum mark, you need to add more coolant.
- If the level is above the maximum mark, you need to drain some coolant.
It’s also a good idea to check the color of the coolant. Most modern cars use a green or yellow coolant, but some older cars may use a different color. If you’re unsure what color your coolant should be, consult your owner’s manual or talk to a mechanic.
What to Do If the Coolant Level is Low
If you find that the coolant level is low, you need to add more coolant to the reservoir. You can use a mixture of water and coolant, or you can purchase a pre-mixed coolant from an auto parts store. Be sure to use the correct type of coolant for your car, as using the wrong type can damage the engine.
When adding coolant, be sure to follow these steps:
- Make sure the engine is cold.
- Locate the radiator cap and remove it.
- Pour the coolant into the reservoir slowly, checking the level as you go.
- Replace the radiator cap and start the engine.
- Let the engine run for a few minutes to circulate the new coolant.
Checking Coolant Condition
While checking the coolant level is important, it’s also important to check the condition of the coolant. Over time, the coolant can break down and become less effective, which can lead to engine damage. To check the condition of the coolant, follow these steps:
- Locate the radiator cap and remove it.
- Look for any signs of rust, corrosion, or sediment in the coolant.
- Check the color of the coolant. If it’s darker than usual, it may be a sign that the coolant is breaking down.
- Use a coolant test strip to check the pH level of the coolant. If the pH level is off, it may be a sign that the coolant is breaking down.
If you find that the coolant is in poor condition, you need to drain and replace it with new coolant. Be sure to follow these steps: (See: Change Coolant Reservoir Tank Bmw)
