What is the wheel size of the Avalon?

The Avalon comes with two wheel sizes: 215/55R17 and 235/45R18. Here are the details: 1. Introduction: The wheel hub is the rotating part of the tire's inner rim connected to the wheel center via spokes, which is the metal component mounted on the axle that supports the tire. It is also called the rim, steel wheel, or wheel disc. Wheel hubs come in various types based on diameter, width, manufacturing method, and material. 2. Classification: The wheel hub is also known as the rim. Depending on the characteristics and requirements of different vehicle models, the surface treatment process of the wheel hub varies, mainly divided into painting and plating. For standard vehicle models, the appearance of the wheel hub is less of a consideration, with good heat dissipation being a basic requirement. The process typically involves painting, which includes spraying followed by baking, offering cost-effectiveness, vibrant colors, and long-lasting durability. Even when the vehicle is scrapped, the wheel hub's color remains unchanged. Many Volkswagen models use painted wheel hubs. Some trendy and dynamic colored wheel hubs also employ painting technology.

What is the function of a reversing radar?

The main function of a reversing radar is to automatically activate when reversing, allowing the driver to know if there are obstacles behind the vehicle without turning their head, making parking and reversing easier and safer. Below is more information about car reversing radars: 1. A car reversing radar, also known as a reversing collision avoidance radar, is a safety assist device that functions during reversing. It informs the driver about obstacles around the vehicle through sound or a display screen, addressing the difficulties of inspecting blind spots while reversing, parking, or starting the car. It helps drivers overcome the limitations of blurred vision and blind spots. Using ultrasonic principles, the radar sends ultrasonic waves from the rear probe to detect obstacles and measures their distance, providing alerts to the driver. 2. A reversing radar mainly consists of a display, controller, and ultrasonic sensors. The controller processes signals and calculates the position and distance between obstacles and the vehicle body. The ultrasonic sensors primarily emit and receive ultrasonic signals, inputting the data into the main unit, which is then displayed on the screen. When the sensors detect that the obstacle distance reaches a dangerous range, the system issues a warning through the display to alert the driver.

How much gasoline should be added with 100ml fuel additive?

100ml fuel additive is suitable for 60-100 liters of gasoline. The purpose of fuel additive is to solve the carbon deposit problem in the fuel system of fuel injection vehicles, quickly restore the engine to optimal working condition, compensate for certain deficiencies in gasoline properties, and provide gasoline with improved atomization, reduced wear, engine protection, and lower emissions characteristics. During the actual refueling process, the amount of fuel may exceed the calibrated volume. This is because the fuel tank capacity marked by automobile manufacturers is measured from the bottom of the tank to the safety level, and there is still some space from the safety level to the tank opening. This space ensures that the fuel in the tank can expand when the temperature rises without overflowing from the tank. If the fuel is filled up to the tank opening during refueling, the actual refueling amount will be greater than the calibrated fuel tank capacity. If car owners want to know the remaining fuel level in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it means the fuel is almost empty, and when it is close to F, it means the fuel level is sufficient.

Are the engines of the Avalon and the Allion the same?

The engines of the Avalon and the Allion are the same. Here are the specific details: 1. Different power outputs: The Avalon is equipped with a 2.5L naturally aspirated engine; the Allion is equipped with a 2.0L naturally aspirated engine. 2. Different dimensions: The Avalon's length, width, and height are 4975mm, 1850mm, and 1450mm respectively; the Allion's length, width, and height are 4720mm, 1780mm, and 1435mm respectively. The Avalon offers a dual-tone interior design, featuring a 9-inch multimedia touchscreen, a multifunction steering wheel wrapped in genuine leather, traditional needle-style gauges on both sides of the instrument panel, a 7-inch HUD display in the center, and driving mode switch buttons and an electronic parking brake behind the gearshift.

Can New Crankshaft and New Bearings Be Installed Directly?

New crankshaft and new bearings cannot be installed directly. Here are the details: 1. Introduction: The crankshaft is the most important component in an engine. It bears the force transmitted by the connecting rod and converts it into torque, which is then output through the crankshaft to drive other engine accessories. The crankshaft is subjected to centrifugal forces from rotating masses, periodically varying gas inertial forces, and reciprocating inertial forces, causing it to endure bending and torsional loads. Therefore, the crankshaft must have sufficient strength and stiffness, with wear-resistant journal surfaces, uniform operation, and good balance. 2. Casting Technology: Melting: Obtaining high-temperature, low-sulfur pure molten iron is key to producing high-quality ductile iron. Molding: Airflow impact molding is significantly superior to clay sand molding, enabling high-precision crankshaft castings. The sand molds produced by this process feature no rebound deformation, which is particularly important for multi-throw crankshafts. Electroslag Melting: Electroslag remelting technology applied to crankshaft production allows cast crankshafts to potentially match the performance of forged ones. It also offers advantages such as fast R&D cycles, high metal utilization, simple equipment, and superior product performance.

How to Deal with a Dropped Car Roof Liner?

You can use professional automotive roof liner repair adhesive for fixing, or go to a 4S shop to replace the roof liner with a new one. More details are as follows: 1. Aging of the fabric sponge is very likely to cause the edges of the roof liner to come unglued. The problem of edges falling off is very easy to fix—just buy a bottle of specialized repair adhesive to fix it. If the middle part of the car roof sags or falls off, this issue might be inconvenient to repair. You can opt for clip-on repair, but this method is not very aesthetically pleasing. 2. If the car roof liner falls off over a large area, you will need to go to a 4S shop for replacement. Although this repair method is somewhat more expensive, the result is very aesthetically pleasing. 3. The original roof liner fabric includes a sponge layer. Aging of the sponge layer can cause the roof liner to fall off. When removing the sponge layer, using a brass wire brush can make it easier to remove that layer of sponge, after which you can proceed with the repair. 4. Repairing the car roof liner requires the use of specialized adhesive. Automotive roof liner repair has relatively high requirements for adhesive—you must choose an adhesive with strong viscosity and sun protection. This is because high temperatures in summer can cause the interior temperature to rise rapidly, and using inferior adhesive can easily lead to melting.
