How to Check Tire Pressure on the Tire?

What does it mean to check the coolant level with the engine off?

The prompt to check the coolant level with the engine off indicates that the vehicle's antifreeze is low, and it is necessary to promptly inspect whether the antifreeze level is too low. If the level is too low, antifreeze should be added immediately. Only when the indicator light turns off can you continue driving. Coolant is essentially the engine's cooling water; you can add coolant, or if coolant is not available, water can be used temporarily. However, it's important to check for any leaks. If there is a leak, adding water should suffice temporarily, but ensure it's sufficient. Here is additional information: 1. Function of the cooling system: The purpose of the car's cooling system is to dissipate some of the heat absorbed by heated components in a timely manner, ensuring the engine operates at the most suitable temperature. Engine cooling systems can be either air-cooled or liquid-cooled. A system that uses air as the cooling medium is called an air-cooled system, while one that uses coolant as the medium is called a liquid-cooled system. 2. Components of the cooling system: The cooling system of a car engine is a forced-circulation liquid-cooled system, which uses a water pump to increase the pressure of the coolant, forcing it to circulate through the engine. The cooling system mainly consists of the water pump, radiator, cooling fan, expansion tank, thermostat, water jackets in the engine block and cylinder head, and other auxiliary components.

Does the Tharu consume engine oil?

The Tharu's engine may experience some oil consumption, but this primarily applies to older models. Newer Tharu models generally have less oil consumption unless there is a vehicle malfunction. Engine oil naturally has a certain level of consumption, but excessive consumption indicates an oil-burning issue. Many factors can influence oil consumption, such as fuel quality, driving conditions, driving habits, and maintenance practices. These factors can exacerbate oil consumption in the Tharu, leading to oil burning. "Oil burning" can manifest in two ways: the first is cold-start oil burning, where thick blue smoke is emitted from the exhaust pipe during the first morning startup, disappearing after a while. The second is acceleration-induced oil burning, where large amounts of blue smoke are emitted from the exhaust pipe during hard acceleration while driving or when revving the engine while stationary. Methods to prevent oil burning in cars: Oil selection: For older vehicles with significant mileage, the gap between the piston and cylinder wall may widen. In such cases, thicker oil can be chosen to enhance sealing. Additionally, oil quality is crucial. Owners with the means should opt for qualified semi-synthetic or full-synthetic oils. Although maintenance costs may increase slightly, these oils have a longer lifespan, slower degradation, and better thermal stability and resistance to viscosity changes. Avoid aggressive driving in new cars: Generally, modern new cars do not require a break-in period, but during the first 2,000 kilometers, internal components like the engine and transmission need time to achieve optimal alignment. During this period, avoid behaviors like flooring the accelerator or high RPMs (exceeding 4,000 RPM) to prevent oil burning caused by poor internal component alignment. Regular and timely maintenance: Engine oil operates in a harsh environment, and even full-synthetic oil cannot perform well if not changed regularly. Additionally, oil filters and air filters are critical and should be replaced on schedule to prevent contaminants from entering the cylinder and causing wear.

What to Do When the Vehicle Deviates from Direction During Braking on Icy Roads?

When you notice the vehicle deviating from its direction during braking on icy roads, avoid using emergency braking or sharp steering to evade. Instead, make full use of the engine's drag effect to decelerate or stop. The most crucial aspect of driving in snowy conditions is heightened attention—stay focused, maintain a steady speed, keep a safe distance, and utilize the engine's braking effect to reduce speed as much as possible. Here are some precautions for driving in snowy conditions: Reduce speed: Due to the extremely low adhesion of icy roads, to prevent skidding or collisions with other vehicles, drive at a reduced speed and maintain a safe distance. The longitudinal safe distance should be three times that on dry roads. Make full use of engine braking: To decelerate or stop on icy roads, rely heavily on the engine's braking effect to reduce speed. Avoid using the foot brake whenever possible. If braking is necessary, apply it intermittently and lightly, supplemented by the parking brake. Turn the steering wheel slowly on icy roads: When turning on icy roads, gradually release the accelerator pedal in advance to decelerate smoothly, then turn the steering wheel slowly. Avoid abrupt movements. If road and traffic conditions permit, increase the turning radius appropriately to turn earlier or less sharply, preventing wheel skidding. Decelerate in advance when meeting another vehicle: When encountering another vehicle on icy roads, choose a safe, wide section of the road, decelerate in advance, stabilize the steering wheel, and pass slowly on the right side. Try to maximize the lateral distance between vehicles and maintain an appropriate distance from the roadside. If necessary, stop and yield. If the meeting point is unsuitable, do not force the encounter. Depending on the road conditions, one vehicle should reverse to yield, avoiding any aggressive maneuvers. No overtaking on icy roads: Overtaking is generally not allowed on icy roads. If absolutely necessary, choose a wide, flat section with minimal snow and ice. Only overtake after the preceding vehicle has yielded and decelerated. Avoid forced overtaking or high-speed overtaking to prevent accidents.

What to Do When Water Leaks from the Sunroof into the Area Under the Driver's Seat?

Water inside the car can be quickly dried by wiping, ventilating, or pumping it out. However, drivers should not attempt these operations themselves, as accumulated water can cause short circuits in the vehicle's electrical system. It is recommended to go to the nearest repair shop for professional assistance. Below are detailed steps for cleaning up water inside the car: Thoroughly Remove Water from the Car: If the water accumulation is solely due to rain, simply opening the car windows on a sunny day to air it out thoroughly may suffice. If water has entered the cabin, the repair process mainly involves draining the accumulated water. There are several rubber seals located at the bottom of the vehicle's chassis; opening these seals can allow the water inside the cabin to drain out. However, since the car's floor mats and other interior materials are highly absorbent, they should be removed and placed in a spacious area to facilitate evaporation. If there is still moisture inside the car, it is advisable to turn on the air conditioning and set the circulation mode to internal recirculation. This allows the moisture inside the cabin to be expelled through the air conditioning system—a very efficient dehumidification method, especially in summer. Clean and Dry Interior Items: Rain can easily bring dirt and mud into the car. On sunny days, removable interior items such as floor mats and seat covers should be taken out to air and clean. For carpets that are not too dirty, a vacuum cleaner can be used directly. For dirtier carpets, specialized cleaning agents should be applied. First, remove dust, then spray an appropriate amount of cleaning agent and scrub. Note that carpets should not be completely soaked in water for scrubbing, as this can damage the adhesive layers between different materials inside the carpet and prolong drying time, affecting usability and causing dampness inside the car. Disinfect and Thoroughly Clean: Seats and seat covers should be washed with bleach, and absorbent cotton must be replaced to prevent bacterial growth. Ozone disinfection can also be performed. The air conditioning's evaporator box should be disassembled, rinsed, disinfected, and dried. The blower should also be cleaned carefully. Additionally, perform air purification inside the car using technologies like "photocatalysis" to improve air quality.

How to Resolve the 'Vehicle Previously Hacked' Alert on Buick Cars?

When a vehicle is hacked, corresponding fault information will be stored in the ECU (Electronic Control Unit) or displayed on the dashboard. In such cases, it is essential to promptly visit an authorized repair facility for inspection and clearance of the alert, as well as to determine the cause of the hacking notification. Hacking refers to intentional unauthorized attempts to access information, process data, or disrupt the system to render it unreliable or unusable. The automotive comprehensive performance testing line is a vehicle inspection system that integrates modern detection technology, electronics, and computer applications to conduct non-destructive testing and diagnostics on vehicles. The testing line is divided into three sections: the first section, which the vehicle enters initially, primarily tests speed, emissions, and chassis; the second section focuses on braking performance, consisting of an axle weight measurement platform and a brake testing platform; and the third section measures parameters such as side slip, lighting, and sound levels. If there is a chassis dynamometer or engine test, it is also conducted in this section. After the vehicle enters the testing line, an LED dot-matrix display provides instructions, and the driver operates according to the prompts on the screen. The trigger signal for testing is provided by a photoelectric switch. The testing process is as follows: First, the vehicle information of the car to be inspected is logged into the login computer, where all vehicles awaiting inspection are queued. When the first testing station is available, the system prompts the vehicle to proceed. When the designated drive axle enters the speed testing platform, the lifting plate of the speed testing platform descends under the control of the main computer, and a speed test prompt appears on the display. Typically, a 40 km/h test is conducted, meaning the driver adjusts the speed to 40 km/h, and the computer records the actual speed. After the test, the lifting plate raises the wheels, and the vehicle moves to the next test item. The second section primarily tests braking performance, using a single-axle reaction force drum brake tester, with the motor driven by an electrical cabinet controlled by the main computer. The vehicle then proceeds to the third station, where lighting is tested using a lighting tester, and side slip is measured as the vehicle exits. After completing the tests, the main computer transmits the data to the data computer, which prints the data in a specified format and stores it in a database for future queries. The system allows multiple vehicles to be tested simultaneously, ensuring high efficiency.
