Are you one of those who checks in the car only when you travel? If you answered yes, you probably are not taking care of your vehicle as it should.
When you program to hit the road, do you check all or just a few items when given time? The driver should always analyze several things like: transmission fluid, battery, air filter, radiator water, lights, tires, among others. But not everyone does it.
It is necessary to look at these items not only when you travel, you have to stay alert and check frequently in the day to day. Know your car well and if in doubt, it is always recommended to take them in the vehicle’s manual.
An automobile runs at high temperatures, at the moment of combustion, that temperature can be high. That is why the radiator is very important, it is responsible for cooling the entire system and also for keeping the propeller cooler avoiding overheating and melting the parts. For this reason, it is essential to always keep an eye.
How does the cooling system work?
Do you know how all this works and what are the rich when there is water in the radiator reservoir? This system consists of thermostatic valve, expansion tank, vacuum valve, pressurizing valve, cooling fluid, water pump, electro-fan and temperature sensor of the motor.
The thermostatic valve is the part that divides between the engine fluid and the radiator. It has the function of allowing the rapid heating and maintenance of the temperature to maintain a good functioning of the motor, releasing the hot liquid coming from the block (of the motor) to the radiator.
It crosses the radiator and is cooled, thus returning to the block. The thermal switch turns on the fan in case the air flow that passes through it is not enough. This usually happens when the car is on and the car is stopped in a slow transit, for example.
The switch is triggered when the bimetallic disks dilate with heat, causing components to move inside, turning the fan on and off. The temperature sensor is located in different parts of the engine. It has a ceramic insert called a thermistor, when the temperature is low, the electrical resistance of the thermistor is high, making it impossible to pass electric current to the panel pointer of the car.
The electronic injection sensor works similarly to the common temperature sensor, the information is sent to the electronic control module. With this information, it controls the fuel injection time, the ignition point, the lambda sensor and the radiator fan.
What happens when there is no water?
Now we know that he is responsible for controlling the temperature. This way, there is no shortage of water in the tank. But when does this happen?
With overheating due to lack of water, problems arise, which can damage the engine gaskets and the water pump. In addition, it runs the risk of melting the engine and with that it will need to be removed from the vehicle for a grinding service , explains. However, with the technology in modern engines, this ends up being much rarer.
What to put in the reservoir? Can it be just water?
The liquid that must go in the radiator is not 100% water, otherwise the motorization rust may occur. So use the right product: the coolant and additives, which is a compound that uses ethylene glycol to help maintain the temperature and cleaning inside the engine (50% water and 50% additive).
When it is necessary to replace it because it has been lowered, in emergency cases you can even put “tap water”, but it is essential to check for leaks . Then find a repairer to have the coolant replaced immediately.
What to do when there is water and the engine boils?
When identifying the problem, it is crucial to wait for the car to cool before opening the tank. Turn off the vehicle and wait about 10 – 15 minutes.
Still, under no circumstances do you put cold water, some people think it might help, but in fact, it may cause a thermal shock. After that, turn on the car to see if the temperature will rise, if it does, it could be a mechanical problem.
If the engine is still warm, the environment is pressurized, this water can “splash” causing severe burns. Already at the time of the change, it is necessary to withdraw all the liquid and then just put the new one. The total volume varies from vehicle to vehicle, usually about 4 liters or more.
Radiator additives and periodic maintenance
There are a number of radiator additives that are offered. As we have a variety of variety on the market, some manufacturers do not provide the correct composition, so use the most famous brands that are already reliable and do not just look at the price. The exchange of the liquid of the reservoir must occur, according to the assemblers, every two years or when leaks are detected.
You must be careful to always leave the water level. Verification should be done periodically. In the case of older vehicles, the owner needs to look more often, usually in the morning, before leaving with the car, as there may be minor leaks. Already on newer models at least once a week.
The system may also show signs of problems; if you notice that the water is reddish or brown, this may be an alert, possibly causing clogging, causing overheating even if the reservoir level is high. Even the lid should be changed every 30,000 kilometers.
How to cover a hole temporarily?
Put a raw egg in the radiator to plug a hole, okay? No lies, there are people on the internet who say they have been able to solve this problem for some time. There is no piece with that name no. We’re talking about putting even a raw egg inside the radiator . Some say even tomato paste works. We talked about this in another post and you can check whether this is right or not.
When the engine works at the correct temperature, it will have longer durability, you avoid excessive fuel costs, the pollutant content will be lower, the performance will be high and you will also have less wear and friction. In addition, of course, lower maintenance cost.
