The Difference Between Antifreeze and Coolant?

There is no difference between antifreeze and coolant; they are the same liquid. More information about antifreeze and coolant is as follows: 1. The full name of antifreeze and coolant is antifreeze coolant, meaning a coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and cracking the radiator or damaging the engine cylinder block when the vehicle is parked in cold seasons. 2. The engine and its cooling system are made of metal, including copper, iron, aluminum, steel, and solder. These metals, when in contact with water at high temperatures for a long time, can corrode and rust. Antifreeze not only does not cause corrosion to the engine cooling system but also has anti-corrosion and rust-removing functions.

Where is the oil dipstick located on a BMW?

BMW vehicles do not have a traditional oil dipstick. To check the oil level, you can use the electronic oil dipstick in the iDrive multimedia system or find the oil level option on the instrument panel. Engine oil, also known as motor lubricant, protects the engine from high-temperature damage, helps clean impurities in the engine cylinders to some extent, and primarily serves a lubrication function. The BMW company originally started by manufacturing aircraft engines, leading many to believe its logo represents rotating propeller blades. However, this is not the case. The meaning behind the blue-and-white symmetrical logo is quite simple - the blue and white pattern is derived from the state emblem of Bavaria, where the company is headquartered, symbolizing BMW's authentic Bavarian heritage.

How to Remove Cement Dust from a Car?

To remove cement dust from a car, you will need water, white vinegar, a towel or gloves, a hairdryer, acidic water, and methods such as wet soaking, acidic dissolution, and rinsing. Below are the detailed steps: 1. If the cement has been on the car for less than 12 hours, the best approach is to first wet and soak it with water, then use car wash soap and a towel to clean it slowly. 2. If the cement has been on the car for more than 12 hours, it will have hardened. You can purchase acidic water from a pharmacy, apply it to the cement with a brush, and the cement will dissolve in the acidic liquid. Finally, rinse it off with water. If it is difficult to remove, you can use hydrochloric acid because cement is alkaline and hydrochloric acid is a strong acid. Applying it to the cement will dissolve it immediately without damaging the car body, and then you can rinse it off. 3. If the cement covers a large area, you can pour gasoline on it. Once the paint softens, you can manually remove the cement. 4. Use a hairdryer to heat the area with cement, and the cement will fall off automatically. 5. Spray white vinegar on the cement using a spray bottle, wait for 3-5 minutes, and then gently scrape it off with an old bank card. The cement will come off in chunks. Finally, rinse the area where the white vinegar was applied with car wash soap.
