Maintaining an ample supply of engine coolant is paramount for the smooth operation of your vehicle. It’s crucial to monitor and replenish your coolant reservoir, usually located under the hood and in close proximity to the engine, at least once or twice annually. Failure to do so can result in detrimental effects on your car’s internal components. In this guide, we’ll walk you through topping up your coolant reservoir and offer expert advice on when to add or replace coolant for optimal vehicle performance and longevity.
How Do I Know If My Car Needs Coolant?
To ascertain if your car requires coolant, observe the temperature gauge on your dashboard while driving. If it indicates an unusually high temperature or your engine overheats, it may be a sign that your vehicle needs coolant.
Another way to check coolant levels is by inspecting the coolant reservoir or radiator. Ensure the engine is cool before opening the reservoir cap. If the level is below the recommended mark, adding coolant can help maintain proper engine temperature.
Additionally, be attentive to any warning lights or messages on your dashboard related to coolant levels. Modern vehicles are equipped with sensors that detect coolant levels and may alert you if they are low or depleted.
By regularly monitoring your car’s temperature gauge, checking coolant levels, and heeding warning lights, you can determine if your vehicle needs coolant and take appropriate action to prevent engine overheating and damage.
Things You Should Know?
Before adding coolant in your car, you should know first,
Identify Correct Coolant Type: Determine the specific type of coolant required for your vehicle, whether it’s ethylene glycol-based or propylene glycol-based, to ensure compatibility and effectiveness.
Check Coolant Levels: Before adding coolant, inspect the coolant level in your car’s reservoir and radiator. If levels are low, adding coolant mixed with an equal amount of water can restore them to the recommended level.
Monitor for Warning Signs: Be vigilant for warning signs indicating potential issues with your vehicle’s cooling system, such as overheating, coolant leaks, or unusual smells. Promptly address any concerns by consulting a professional mechanic for diagnosis and repair.

Coolant vs. Antifreeze
Some common differences between coolant and antifreeze you should know,
| Coolant | Antifreeze |
| Also known as radiator fluid | Also known as engine coolant |
| Used to regulate engine temperature | Used to prevent freezing and overheating |
| Typically a mixture of water and antifreeze | Primarily composed of ethylene glycol or propylene glycol |
| Helps dissipate heat from the engine | Lowers the freezing point and raises the boiling point of the coolant mixture |
| Comes in various colors, such as green, red, or blue | Often dyed a distinctive color, such as green or orange |
| Protects against corrosion and rust within the cooling system | Acts as a lubricant for water pump seals and prevents corrosion |
Do You Add Coolant To Radiator Or Reservoir?
When it comes to adding coolant to your car, you typically pour it into the coolant reservoir, not directly into the radiator. The coolant reservoir serves as a convenient access point for topping up coolant levels without needing to open the radiator cap.
Pouring coolant into the reservoir allows it to gradually mix with the existing coolant in the system as needed. This helps maintain the proper coolant-to-water ratio and ensures efficient engine cooling performance.
Adding coolant to the reservoir also minimizes the risk of burns or injuries that could occur from opening the radiator cap while the engine is hot. It’s a safer and more convenient method for maintaining optimal coolant levels in your vehicle.
What Happens If You Put Coolant In The Radiator?
If you put coolant directly into the radiator, it will mix with the existing coolant in the cooling system. This can help replenish coolant levels and maintain proper engine temperature regulation.
However, it’s important to ensure that you’re using the correct type of coolant for your vehicle and that it’s mixed with distilled water to achieve the proper coolant-to-water ratio. Using the wrong type of coolant or mixing incompatible coolant types can lead to damage to your engine or cooling system components.
To avoid potential issues, it’s recommended to add coolant to the coolant reservoir rather than directly into the radiator. This allows the coolant to gradually mix with the existing coolant in the system and helps maintain optimal performance and protection for your engine.

What happens if you put water in coolant reservoir?
Some common issues you have to face by adding water in coolant reservoir,
Effectiveness Compromised: Adding water to the coolant reservoir dilutes the coolant mixture, reducing its ability to regulate engine temperature effectively.
Potential Risks: This dilution can result in decreased coolant performance, increasing the risk of overheating or engine damage over time.
Recommendation for Optimal Protection: To safeguard your engine, it’s advisable to use a mixture of coolant and distilled water in the reservoir. This ensures consistent temperature regulation and provides corrosion protection for engine components.
Corrosion Risk: Pure water lacks the corrosion inhibitors found in coolant, increasing the likelihood of corrosion within the cooling system and potential damage to engine components.
Winter Concerns: In colder climates, using water alone in the coolant reservoir can lead to freezing in low temperatures, causing blockages and potential damage to the cooling system.
Does coolant affect AC?
Coolant plays a crucial role in maintaining the proper functioning of your car’s air conditioning (AC) system. The AC system relies on the circulation of refrigerant to cool the air before it enters the cabin. However, the AC system also utilizes the car’s engine cooling system to dissipate heat generated during operation.
When coolant levels are low or the coolant is not circulating effectively, it can impact the overall performance of the AC system. Inadequate coolant levels can lead to overheating of the engine, which in turn can affect the AC compressor’s ability to function optimally. This may result in reduced cooling capacity or even complete failure of the AC system.
Coolant leaks or contamination can cause damage to AC components such as the condenser or evaporator coils, leading to costly repairs. Therefore, it’s essential to ensure that your car’s cooling system is properly maintained, including regular checks of coolant levels and addressing any leaks or issues promptly.
While coolant primarily serves the engine cooling system, it indirectly affects the performance of the AC system. Proper maintenance of the cooling system is crucial to ensure optimal operation of both the engine and the AC system, enhancing overall driving comfort and safety.
