For any vehicle to move, there must be the process of the combustion of fuel. The fuel is combusted to produce heat that is converted into mechanical energy. Through this process, a lot of heat is produced, and for a vehicle not to overheat and function properly, it should have an effective cooling system.
If the cooling system fails to work correctly, then the engine will overheat and cause problems that will have you spend thousands of dollars on repairs. This is where engine coolants come in.
A coolant is a liquid added to a vehicle’s engine to ensure that the liquid in the radiator does not freeze during the winter and that it does not go above the boiling point in the summer. But does coolant evaporate? The radiator is part of the cooling system. The water and the fan in the radiator help to cool down the engine.
Should there be a problem with the radiator, the fan, or the coolant? There are high chances that the engine will overheat and cause problems to the functionality of the car. Does the engine coolant evaporate, or where does it go to? In this article, we will discuss how much coolant loss is normal and the factors that would contribute to coolant loss.
How Much Coolant Loss Is Normal?
Some of the questions car owners ask themselves are: does engine coolant evaporate? Why is my car losing coolant but it has no leaks? Is it normal for the coolant level to drop? The truth is that whether you have a leak or not, coolant evaporation takes place. That means that there may be a chance of depleted coolant levels and no trace of leakage.
If much time passes without checking your coolant or antifreeze levels, then you might be surprised to find out that there is very little or no coolant in your engine. This might be the root of your car’s problems since there is the risk of your engine overheating.
Can antifreeze evaporate? Losing coolant due to evaporation is normal but when it reduces so quickly, it means something is wrong, and you should consider checking other factors that may lead to the decrease.
Causes of a Decrease in Coolant Levels
1. A Damaged Gasket
When the gasket head is damaged due to wear and tear or the high heats in the car engine, there is a possibility that the coolant will spill into the combustion chambers of a car. In the chambers, the coolant will be heated up and burnt off, leading to damage to the engine. White smoke is emitted from the engine.
If you do not want more problems with your car, it would be best to stop the car, let it cool off and examine what the problem is.
2. A Damaged Radiator
The radiator holds the water or the coolant that is supposed to keep cooling the engine when the car is in motion. When either the radiator or its horse pipes are corroded and have holes, the cooling liquid will reduce due to the leaks. Radiators that use water are more prone to rust and corrosion, leading to the radiator losing coolant.
3. A Faulty Cooling System
Will a faulty system lead to coolant evaporation? Why am I losing antifreeze? A car engine has several parts that make up the cooling system. These parts include the pump, thermostat, and radiator fan. The fan ensures that it cools off the hot cooling liquid from the engine to go back in the engine as cold water or coolant and lower the temperatures.
The thermostat is placed in between the engine and the radiator so that the cooling liquid from the engine flows to the radiator through it. The pump ensures that the cooling liquid is pumped from the radiator through the horse pipes and into the cooling engine.
4. A Damaged Reservoir Cap
The reservoir cap’s work is to ensure that the coolant levels are in the right place and that the pressure is maintained so that the coolant travels through the horse pipes and into the engine at the right rate. When the cap is damaged, there will be increased coolant loss.
How to Take Care of A Car Losing Coolant With or Without Leaks
If you’re running into the following issues, then you need to run a diagnostic test in your car. They could be caused by a lower coolant level.
The test will help you answer some of the questions such as why there is depleted coolant levels with no trace of leakage, can coolant evaporate? And, can antifreeze evaporate? consider the following:
• How much coolant are you putting into your system?
You should ensure that the coolant or the antifreeze is below the rubber. Overfilling it will cause some leaks.
• Is your gasket head in perfect shape? Is it tight enough?
When the gasket head is worn out, it will probably not be tight enough. That means that there will be coolant loss no visible leaks.
• Is the radiator hose in good shape?
If the radiator or the hose are worn out, they will lead to the radiator losing coolant.
• Are there cracks in the engine?
Cracks in the engine system will lead to losing the coolant. It will not only cause combustion problems but may lead to overheating of the engine.
• Do you notice leaks below your car after carrying heavy loads?
If you notice some coolant spillage on the ground beneath your car engine, then you should know that something somewhere is wrong. Seek a mechanic to address the problem before it gets huge, and you are required to change the whole engine system.
Visible leaks are evident that there is a problem, but a car losing coolant but no leaks may be very hard to detect.
Coolant loss with no visible leaks or visible leaks requires you to check your car once in a while to see how much of the coolant to lose. A sudden drop in the levels should ring an alarm.
Taking your car for service after every 30,000 miles covered will help you maintain a good cooling system. The overall cooling system should be checked for wear and tear, cracks, and the coolant changed. Changing the rubbers on the gasket head also improves the tank’s tightness so that the coolant evaporation is minimized.
1. Why am I losing antifreeze? Why is my car losing coolant but no leaks?
Losing your antifreeze may be a clear indication that there is a fault in the cooling system, cracks in the engine, or a sudden change in the vehicle’s driving patterns. For example, if your vehicle has been used to ferry light weights for short distances, there could be a noticeable loss in the antifreeze if you carry heavy loads for long distances.
2. Why is my coolant low but no leaks? Does engine coolant evaporate?
Losing coolant but no leaks are very possible because a coolant evaporates with time.
3. Can antifreeze evaporate? Does coolant evaporate?
This has been a huge debate. An antifreeze left in a container in the open air may not evaporate. It is important to note that antifreeze may evaporate due to the constant heating in the car’s reservoir. The evaporation is usually very minimal, and a huge loss is an evidence that there could be a leak.
4. Is it normal for the coolant level to drop? Can coolant evaporate?
Yes, that is very normal. However, it should be at a very slow rate when the cooling system is not faulty. The system may be faulty, losing coolant but no leaks.
5. How often should I refill my coolant?
Depleted coolant levels with no trace of leakage are expected, and that is the reason why you should keep checking your coolant. Ideally, you should refill it after every 30,000 miles and according to your car engine condition. Service your car engine to avoid the question of; why am I losing coolant?
Driving a car without an effective cooling system is calling for more engine troubles. You must invest in a coolant with antifreeze properties if you reside in places with adversely cold weather. A coolant will ensure that your engine runs properly and achieves its optimal capacity.
