Who will win the race? Not only those who are the best in skill and quality. Besides these, you also need to be calm and cool. This helps you to be focused and keep you fit for a longer race. The same thing you can say about your car. To keep the system cool every car is equipped with an engine coolant system. Now let’s have an introduction with engine coolant.
What is An Engine Coolant and How Does it Work?
A great deal of energy produces by a car through burning fuel. Some of it works to move the car, and the rest of it converted to heat. About half of the heats expel through exhaust and remaining heat stays inside the engine. The heated engine needs to be cooled down unless by gradually increasing the temperature the engine can be seized only to put you in trouble with your car. At this point, the engine coolant comes to act.
Engine coolant is a mixture of water and antifreeze liquid that takes away heat from the engine and keeps it cool. The engine coolant or antifreeze is a mixture of distilled water and ethylene glycol or propylene glycol that helps to absorb the heat from the components of your car engine. The engine coolant circulates through the engine, into the radiator, and then back to the engine again. Apart from that, it helps to reduce rust and corrosion from the metal components of the engine and also reduces electrolysis which is the reason behind the decay of the metal parts. Moreover, some coolants are used in extremely cold regions and prevent the liquid inside the engine from freezing.
Why Does the Coolant Need to be Changed?
- Engine coolants tend to get deteriorated over time. After a certain time, the coolant becomes acidic and cannot control heat and rust properly. Then you should think seriously to change it.
- If the engine coolant is not working properly then the radiator, thermostat, water pump and some other parts of the cooling system can be damaged.
What Indicates the Coolant Need to Change?
Some symptoms indicate you that the time has come to change the engine coolant. These are-
- Overheating is the problem which shows that your coolant is not doing its job properly and it needs to be changed.
- A radiator leak is one of the common problems that cause a leak and spill out the coolant. Here you need to go for a mechanic job.
- Sometimes if you feel a sweet smell inside your running car, it means your coolant is about to give up and you need to change it early.
- If your car intakes more fuel than before for equal drive then you also need to take a look at the condition of the coolant which probably needs to be changed.
When Do You Need to Check on the Coolant?
Although your coolant lasts a longer than two weeks, still you need to check on your coolant frequently to see if everything is alright. Normally, you have to check the coolant only after a long drive. Otherwise how much distance you drive every day is to consider for checking the coolant. Apart from that, If your car already has been covered more than 50,000 miles, then it is obvious for you to check your coolant to see if it is in the perfect state or not. The checking should be done with test strips to see the acid level and using a hydrometer to check the cooling and boiling protection.
What if You Miss to Change the Coolant?
If you keep the engine coolant of your car for a too long period it becomes acidic. Then this chemical stops working and it cannot prevent the engine from rust. If that happens then you have to go for expensive services that may pinch your pocket. Moreover, the coolant always saves the radiators from corrosion. So if you don’t change the expired coolant it may damage the cooling system as well as the heater system of your car.
When Do You Need to Change the Coolant?
So, now it is time to know how often you should change the engine coolant of your car. Some rules should be followed which tell you the right time of it.
- For some cars (Hyundai) the coolant should replace after 60,000 miles for THE first time and then this can be repeated after every 30,000 miles. But if you have Mercedes-Benz you can continue with your old coolant for 120,000 miles or 12 years.
- In the most cases, coolant gets contaminated and could not function properly. So you have to flush out your coolant to remove the contaminants without considering how many miles you have covered so far.
- If you notice some rust and corrosions in the cooling system of your car engine then you have to think seriously to replace your coolant to keep everything perfect condition. Unless you have to go for some high expensive repairing.
- In winter states if your age-old coolant doesn’t have properly mixed with water and antifreeze, the water may turn into ice and put pressure on your engine causing damage and even cracks. To prevent this you have to replace the coolant.
- If your coolant gets out of use then the inside of the car becomes hotter. Then you have no way left but changing the engine coolant.
- If the test shows that your coolant is working fine and you’ve no complained of overheating, rust or corrosion, then do not need to replace your coolant before schedule time recommended by the manufacturer.
