Is the New Car Radiator Hot?

Under normal circumstances, as long as the car is running, the new car radiator will also heat up. How the Radiator Works: When the car is running, the temperature of the car radiator will rise, and the pressure inside the radiator will increase. When the pressure inside the radiator reaches a certain level, the pressure valve is pushed open by the pressure, and the coolant flows into the adjacent overflow tank. When the car stops running, the cooling system will draw the water from the overflow tank back. Precautions for Radiator Use: Never fill the car radiator with tap water, as prolonged use of tap water can cause rust or scale buildup in the radiator. This is a very common issue. Rust and scale can restrict the flow of antifreeze in the cooling system, reducing the radiator's heat dissipation performance and, in severe cases, even damaging the engine.

Why does the car shake violently when it is just started?

The reasons for violent shaking when the car is just started are as follows: 1. Poor fuel quality: Inferior fuel has poor volatility, and the engine block temperature is low when starting a cold car, causing the fuel injected into the cylinder to not fully mix with the air, resulting in difficulty starting and severe body shaking. 2. Carbon deposits in the engine valves and intake pipes: Carbon deposits can absorb an appropriate amount of fuel, causing the electronic control unit to make incorrect judgments, failing to provide the power needed for car startup, leading to shaking. 3. Spark plugs: The gap between the spark plug electrodes gradually increases, the ignition energy decreases, and the fuel atomization is poor, causing the car body to shake immediately after starting.

What kind of engine oil does Volvo use?

Volvo's original engine oil brand is Castrol, and the special engine oil models for Volvo include 0W20 or 0W30. Below are specific methods for selecting engine oil for cars: 1. Performance selection: If you care about the long-term effectiveness of the engine oil, you can choose Mobil engine oil; if you focus on the engine oil's cleaning effect on the engine, you can use Shell lubricating oil; if you need lubricating oil with strong oil film toughness, it is recommended to use Castrol. 2. Driving conditions: For frequent driving in congested areas, older vehicles, or long-distance heavy-load transportation, the viscosity of the lubricating oil can be appropriately increased. 3. Engine type: For naturally aspirated engines, mineral oil and semi-synthetic oil can be used. Compared to naturally aspirated engines, turbocharged engines have a more compact structure and harsher operating conditions, requiring higher-grade lubricating oil with better fluidity, preferably fully synthetic oil.

How to Identify Engine Oil Grades?

Methods to identify engine oil grades: The 'S' series represents oil for gasoline engines, while 'C' denotes oil for diesel engines. When both 'S' and 'C' appear simultaneously, it indicates a universal oil suitable for both gasoline and diesel engines. The oil quality ranges from SA up to SL, with later letters in the alphabet indicating higher quality grades. Each subsequent letter signifies improved performance over the previous one, as the oil contains more additives to protect the engine. The oil grades for winter and summer also differ. Winter oil grades are: 0W, 5W, 10W, 15W, 20W, and 25W. The symbol 'W' stands for 'Winter,' and a smaller number before 'W' indicates lower low-temperature viscosity, better low-temperature fluidity, and suitability for lower minimum temperatures. Summer oil grades are: 20, 30, 40, and 50, where a larger number indicates higher viscosity and suitability for higher maximum temperatures.

How to Clean the Outside of a Car Radiator?

Methods for cleaning the outside of a car radiator: 1. Before cleaning, remove the bumper. Ensure all fixing screws are unscrewed during removal, and slowly detach it from both ends towards the middle to avoid breaking the fixing clips; 2. After removing the bumper, the radiator's position can be seen. Adjust the water gun nozzle to a spray pattern and set the pressure to an appropriate level, then rinse the dirty surface of the radiator; 3. After rinsing, check if any cooling fins are damaged. If so, use tweezers or a bamboo skewer to straighten them. Once all checks are complete, reinstall the bumper in the reverse order of removal to finish cleaning the radiator.

What letter represents fully synthetic engine oil?

Fully synthetic engine oil does not have a letter designation. The API of engine oil only represents the oil grade, and there is no necessary connection between the oil grade and whether it is fully synthetic. For example: SN grade is currently a higher grade, but SN grade does not necessarily mean it is all fully synthetic engine oil; there are also semi-synthetic oils. There are two designations for engine oil: one is SAE, and the other is API. SAE is used to indicate the viscosity of the oil, while API is used to indicate the grade of the oil. API is the abbreviation for the American Petroleum Institute, indicating the quality level of the oil. The API designation consists of two letters: the first letter, if it is S, indicates gasoline engines, and if it is C, it indicates diesel engines.

What does the R gear mean in a car?

In a car, the R gear stands for the reverse gear, which is one of the three standard gears in a vehicle. Its function is to enable the car to move in the opposite direction, allowing it to reverse, a feature essential for any automobile. In manual transmission models, the reverse gear also serves as a hill-hold function, where parking on a downhill slope can be secured by engaging the reverse gear to mechanically lock the drive shaft. The method of using the reverse gear is as follows: 1. For manual transmission models: After bringing the vehicle to a complete stop, depress the clutch and brake pedals, then shift into reverse gear, followed by a slight throttle application while partially engaging the clutch. 2. For automatic transmission models: To engage or disengage the R gear, the driver must press the brake pedal and simultaneously press the safety button on the gear lever or push down the gear selector.
