How Long Is the Warranty for a New Steering Gear?

Steering gear, also known as a steering box, generally follows the vehicle's warranty policy, which is typically 3 years or 60,000 kilometers. Below is the classification of automotive steering systems: 1. Mechanical Steering Gear: Mechanical steering gears are widely used and can be categorized into rack-and-pinion steering gears, recirculating-ball steering gears, worm-and-roller steering gears, and worm-and-sector steering gears based on their structural characteristics; 2. Mechanical Hydraulic Power Steering System; 3. Electro-Hydraulic Power Steering System: The electro-hydraulic power steering system simply adds an electronic mechanism to the mechanical hydraulic power steering system; 4. Electric Power Steering System.

How to Close the Car Hood?

Lift the hood to a height of about 30 centimeters, then let it fall freely. You should hear a "clunk" sound when it closes properly. Below are specific details about the hood: 1. Airflow Guidance: For objects moving at high speeds in the air, the air resistance and turbulence generated around the object directly affect its trajectory and speed. The shape of the hood can effectively adjust the direction of airflow relative to the car's movement and the resistance it generates, reducing the impact of airflow on the vehicle. 2. Component Protection: Under the hood are critical components of the car, including the engine, electrical circuits, fuel system, and transmission system. By enhancing the strength and structure of the hood, it can effectively prevent adverse effects such as impacts, corrosion, rain, and electrical interference, ensuring the vehicle operates normally. 3. Aesthetics: The exterior design of a vehicle is a direct reflection of its value. As an essential part of the overall appearance, the hood plays a crucial role in enhancing visual appeal and embodying the concept of the entire car.

How Many Tons Can a Truck Carry?

Generally, mini trucks have a load capacity of less than 1.8 tons, light trucks between 1.8-6 tons, medium trucks between 6-14 tons, heavy trucks between 14-100 tons, and super heavy trucks over 100 tons. Below are the hazards of driving an overloaded vehicle: 1. Damage to road infrastructure: Overloaded vehicles exert loads far exceeding the design capacity of roads and bridges, leading to pavement damage, bridge fractures, and significantly shortened service life. 2. Increased danger: Overloaded vehicles have greater mass and inertia, resulting in longer braking distances and higher risks. Severe overloading can cause tire blowouts, sudden swerving, brake failure, or rollovers due to excessive tire load and deformation. Additionally, overloading affects the vehicle's steering performance, increasing the likelihood of accidents due to loss of steering control. 3. Traffic congestion: Overloaded vehicles cannot maintain normal speeds, occupying lanes for extended periods and directly impacting road traffic flow.

What are the differences between the Borgward BX5 and BX7?

The differences between the Borgward BX5 and BX7 are as follows: 1. Different exterior designs: The BX5 features a youthful and dynamic design as its main theme, making it a safe and intelligent choice for SUVs. The BX7's overall styling is very appealing, with body lines that create a very full-bodied impression. 2. Different powertrains: The BX5 is equipped with a 1.4T turbocharged direct-injection engine, delivering a maximum power of 110kW and a maximum torque of 250N·m, balancing both performance and fuel efficiency. The BX7 is powered by a 2.0TGDI turbocharged direct-injection engine, paired with an Aisin 6-speed automatic transmission. Additionally, it features a 4MAX intelligent all-wheel-drive system with a response time of 0.12 seconds, which automatically analyzes the vehicle's driving conditions and distributes torque rationally to assist drivers in handling challenging situations such as escaping from difficult terrain, driving on slippery roads, navigating medium to high-speed corners, and driving on uphill roads.

What is the classification of diesel engine oil grades?

Diesel engine oil grade classification: 'C' stands for diesel engine oil. From CA, CB, CC, CD, CE, CF, CF-4, CG-4, CH-4, CI-4, to CJ-4, the further the letter is in the alphabet, the higher the oil quality grade. Generally, CD-grade oil is sufficient for ordinary diesel engines, while turbocharged diesel engines require higher-quality oil. The '-4' indicates that the oil is suitable for 4-stroke diesel engines. Here is more related information: API engine oils are divided into two categories: The 'S' series represents oils for gasoline engines, with specifications including API SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN. The 'C' series represents oils for diesel engines. When both 'S' and 'C' letters are present, it indicates that the oil is suitable for both gasoline and diesel engines. SN-grade is currently the highest-grade oil. SJ was the standard in the 1990s, SL in 2001, SM in 2004, and SN in 2010.

How to Solve Volkswagen's Oil Burning Issue?

Volkswagen's oil burning issue can be resolved by cleaning the oil filter, using one barrel of cleaning oil, one GDI set, along with a treatment kit and a repair kit. Below is an introduction to Volkswagen's oil burning problem: 1. "Oil burning" phenomenon: The new generation of Volkswagen engines employs a novel oil lubrication technology, which differs from traditional lubrication methods. Its characteristic is that there are many tiny pits on the cylinder walls to store oil. Theoretically, when the piston moves downward, the oil on the cylinder walls is scraped off by the oil ring, leaving the piston in a "dry friction" state during upward movement (though not entirely, as some oil remains on the cylinder walls, and the clearance between different types of engine cylinder walls varies). At this point, the oil stored in the pits on the cylinder walls comes into play. However, some of this stored oil is consumed during the power stroke, resulting in the so-called "oil burning" phenomenon. 2. Oil viscosity standards: Using poor-quality oil or oil that does not meet the required viscosity grade can accelerate wear. Additionally, oil viscosity that is too low or too high can lead to poor engine lubrication, increased wear on piston rings and cylinder walls, reduced sealing performance, and ultimately oil burning. It is recommended to use the appropriate oil viscosity standard for maintenance.
