What Does the Wrench Warning Light Mean?

The wrench warning light is a maintenance indicator, reminding you that it's time for maintenance. Below are the car maintenance intervals and maintenance items: Car Maintenance Intervals: The maintenance interval is preset when the vehicle leaves the factory, so the "small wrench" light will appear after a certain mileage, reminding the driver to perform maintenance in time. Typically, the maintenance interval is every 5,000-8,000 kilometers, while the factory-set interval is slightly longer than 8,000 kilometers. After maintenance, the warning light needs to be reset following a specific procedure to turn it off. If the light remains on after maintenance, simply reset it. Routine Maintenance Items: Engine Oil Maintenance: Engine oil, also known as lubricating oil, helps reduce engine wear and provides cooling and lubrication. There are three types of engine oil: Full Synthetic Oil: Replace every 10,000-12,000 kilometers. If the car is not driven frequently, the oil may emulsify and lose effectiveness, requiring replacement after about a year. Semi-Synthetic Oil: Replace every 8,000-10,000 kilometers. Mineral Oil: Replace every 5,000 kilometers.

What lights should be turned on when temporarily parking?

During the day, no lights are required for temporary parking. At night, temporary parking requires the hazard warning flashers, clearance lights, and rear position lights to be turned on. Hazard warning flashers for temporary parking: The hazard warning flashers, commonly known as 'double flash' (a red triangle with an exclamation mark button switch, also called hazard lights or emergency flashers), are signal lights used to alert other vehicles and pedestrians that the vehicle is in a special situation. Clearance lights for temporary parking: Clearance lights are the outermost lights at the front and rear of the vehicle. Large trucks also have clearance lights on the roof and sides. Front and rear position lights for temporary parking: Front and rear position lights, commonly known as small lights or width indicators, are mainly used to indicate the presence of the vehicle and its approximate width, helping other vehicles make judgments during passing and overtaking.

Where Could the Problem of Car Resonance Be?

Car resonance can be caused by aging rubber in engine mounts, engine misfire, or deformation/improper installation of the engine guard plate. Below are detailed explanations: Aging Rubber in Engine Mounts: If the car has been used for a long time, the high-temperature fatigue aging of the rubber in engine mounts can easily cause resonance, and in severe cases, there may even be bumping and friction noises. Engine Misfire: Engine misfire can also cause resonance in the engine. Deformation or Improper Installation of the Engine Guard Plate: Resonance caused by deformation or improper installation of the engine guard plate is relatively common and easy to resolve.

Can You Still Drive with a Tire Pressure of 196?

A tire pressure of 196 is not suitable for normal driving, and it is recommended to inflate the tires as soon as possible. Low tire pressure increases the contact area between the tire and the ground, leading to abnormal temperature rise inside the tire during driving. Additionally, severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, increasing the risk of a blowout. It also results in higher fuel consumption and reduced tire lifespan. The relationship between tire pressure and vehicle handling stability: Cornering stiffness is a crucial parameter that determines a vehicle's handling stability. Tires should have high cornering stiffness to ensure good handling stability. Tire pressure is a significant factor affecting cornering stiffness—higher tire pressure increases cornering stiffness, but beyond a certain point, stiffness no longer changes. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar.

What is the i-Size Certification for Child Car Seats?

"i-Size" refers to the latest child car seat standard issued by the European Union. It is an update to the previous standard, ECE R44. Here are the relevant details: Advantages of i-Size certification: Previous car seat tests only assessed impacts from the front and rear. However, in real-life scenarios, a significant portion of traffic accidents involve side impacts, which were not included in prior testing. The i-Size standard incorporates side-impact testing and introduces adjustments and updates in installation methods and classification standards, thereby raising the safety standards for child car seats. Implementation of i-Size certification: The i-Size certification is already in effect. Currently, both ECE R44 and i-Size standards are being implemented, each with different focuses. i-Size tests all car seats equipped with ISOFIX, while seats secured with vehicle seat belts undergo ECE R44 testing.

What's the reason for the oil pump not making noise after turning on the diesel heater?

The reason the oil pump does not make noise after turning on the diesel heater is due to damage or blockage of the oil pump. Solution: Remove the oil pump and clean it. If it is damaged, replace it with a new one directly. The diesel heater, also known as a parking heater, is suitable for preheating diesel engines in cold regions, effectively solving issues such as engine failure to start or difficulty starting due to cold weather. Circulation components of the diesel heater system: The diesel heater system consists of two cycles: a combustion cycle and a heating cycle. Solution: In the combustion cycle, the oil pump draws diesel from the fuel tank to the combustion chamber, where it is ignited by the igniter. The large amount of heat generated by diesel combustion is transferred through the aluminum alloy fins on the outer wall of the combustion chamber, and the exhaust gas is discharged from the exhaust port. In the heating cycle, the fan draws in external cold air, which passes through the aluminum alloy fins on the outer wall of the combustion chamber and is heated into high-temperature air, then delivered to the cabin to increase the temperature inside.
