1. Engine oil
There is no doubt that this is the most important car repair check and you should do it regularly. Test and check the oil level each time you refuel to avoid unnecessary engine wear and engine overheating. Keep in mind that the oil warning light will not remind you to reload, but will tell you that the oil level is too low. So be sure to check if your oil comes out of its ugly head.
The coolant is obtained from a mixture of antifreeze and water (Hot Car Care) and has three main functions. The first thing to do is to avoid boiling; the antifreeze boils at temperatures above water, so in the case of mixing, the higher boiling point prevents the refrigerant from becoming a gas. Why is it good? Because the gas is not well suited for heat transfer, it is not very useful if the engine must be kept cool.
The second major function of the coolant is to prevent freezing, stopping the engine, water pipes and radiators so that they do not break during the winter. This lower freezing point is also an advantage of the antifreeze, which freezes at temperatures much lower than the temperature of the water, typically in the range of -25° to -60°.
The third important function of the refrigerant is to prevent corrosion of the cooling system, which is achieved by chemicals added to the antifreeze. The cooling system contains a pump that moves the coolant to prevent the coolant from building up.
The point to delete is that if you are charging the cooling system, don’t just use tap water!
3. Brake fluid
Brakes use a friction material to slow down the car, which generates a lot of heat. As a result, the brake fluid must handle extreme temperatures without the use of gas. When the brakes wear out, the brake fluid level naturally decreases over time, which means you need to add it to the common controls you perform under the hood. Over time, the brake fluid also absorbs moisture from the air, which lowers the boiling point of the liquid. This results in reduced brake efficiency and may result in a sponge feel on the brake pedal; the brake fluid must be replaced every two to three years.
4. Power steering fluid.
Depending on the type of power steering system installed in the car, you can operate with hydraulic oil. The level of power steering should not be too low. Therefore, if you need to refill regularly, make sure the system is not leaking. Today, more and more cars are equipped with electric power steering systems (EPAS) that consume less fuel. In a car equipped with such a power steering system, there is no liquid to be inspected.
5. Cleaning the screen
Well, not cleaning the screen will not cause a malfunction, but if you miss the winter, you will know how annoying it is to eliminate dirt and salt. Fortunately, charging is easier; mix a little washing solution with the concentrate or buy it and mix it up until it is full.
But remember two important things. First, do not use detergent to clean the screen, as salt and detergent can damage the paint. Second, don’t cut corners, just use water. In the worst case, the bottle of the washing machine may break and one of the pipes will supply water to the spout of the washing machine. The best case is that you cannot clear the screen because the entire system is frozen. Screen Wash contains mild antifreeze to avoid this.
6. Cleaning the blade
As mentioned earlier, a bad wiper does not stop the car, but they are important anyway. Worn, worn or broken wiper blades are much worse than rain or dew on clean roads (Hot Car Care). They scream every time they try to clean the screen, which is enough for them to throw away and get new settings.
