What is Bridgestone Tire

Bridgestone is a tire brand under Roadtaler, which is a Sino-Korean joint venture tire brand. Functions of tires: Automobile tires are one of the important components of a vehicle. They directly contact the road surface and work together with the suspension system to absorb shocks during driving, ensuring good ride comfort and smoothness. They also ensure excellent adhesion between the wheels and the road surface, improving the vehicle's traction, braking, and off-road capabilities. Precautions for tire usage: All tires on the vehicle, including the spare tire, must be inspected monthly. During inspection, observe the tire surface for cracks or scratches. It is best to wear gloves and check the inner side of the tire for any suspicious marks. If any suspicious signs are found, immediately have a detailed inspection performed by a professional mechanic.

What does the R in manual transmission mean?

R gear is the reverse gear. When the transmission is shifted into this gear, lightly pressing the accelerator will make the vehicle move backward, thus completing the reversing operation. Make sure the vehicle is completely stopped before shifting into R gear, otherwise it may cause reverse impact on the transmission and damage the internal gears. Here is some relevant information: 1. Manual transmissions usually have five gears, but there are also six-speed manual transmissions. The six-speed manual transmission has one more gear than the five-speed, which is the highest forward gear. 2. Automatic transmissions do not require the driver to shift gears manually. The car will automatically select the appropriate gear based on speed or traffic conditions, and the driver only needs to control the accelerator pedal. Automatic transmission cars have six gears, from top to bottom: Park (P), Reverse (R), Neutral (N), Drive (D), Sport or Sport mode (S), and Low (L).

What do 180turbo and 220turbo mean?

180turbo refers to a 1.0T turbocharged engine, while 220turbo refers to a 1.5T turbocharged engine. Specific meanings: Taking 220turbo as an example, the 220 in 220turbo represents the engine's maximum torque, and turbo stands for turbocharging, indicating that this vehicle model uses a turbocharged engine. The 220turbo car model is equipped with a 1.5-liter turbocharged engine, which has a maximum torque of 226 Nm. Turbocharged engine: Turbocharging is an intake method that uses the exhaust gas generated by the operation of an internal combustion engine (Internal-Combustion-Engine) to drive an air compressor (Air-compressor). Under the premise of the same displacement, it can significantly increase the engine's power and torque by approximately 40%.

What is the normal temperature range for a car radiator?

Car radiator temperature hovering around 90°C is considered normal. Generally, engine coolant temperature gauges use either physical or virtual dial pointers for display, while a few vehicles may lack dashboard indicators and only show warning symbols when temperatures become excessively high. Both physical and virtual temperature gauges typically have similar pointer positions. Here's relevant information: 1. If the engine compartment accumulates excessive dust due to prolonged lack of cleaning, it can lead to poor radiator heat dissipation, resulting in overheating. Normally, overheating caused by excessive dust on the radiator can be resolved simply by cleaning the dust off the radiator. 2. Fan failure to operate can cause insufficient radiator cooling, leading to overheating. There are multiple potential causes for fan malfunction, including fan motor failure, thermostat failure, or blown fan fuse - any of which could prevent the fan from operating.

Why Can't the Steering Wheel Turn?

Steering wheel cannot turn because the steering lock function is triggered when the car is turned off. Solutions for steering wheel not turning: If you turn the steering wheel while the car is off, the steering lock will automatically engage, preventing the wheel from turning. In this case, you can try turning the ignition key while simultaneously turning the steering wheel. This will release the steering lock, allowing the vehicle to start normally and the steering wheel to turn freely. Precautions for using the steering wheel: Avoid turning the steering wheel while the car is stationary; try to steer only after the vehicle starts moving. When parking, always return the steering wheel to the center position to prevent unnecessary stress on the suspension system and tires. When making U-turns, try to avoid turning the steering wheel to its extreme positions. It is recommended to visit a 4S shop for a thorough inspection to identify and resolve any potential issues promptly.

How Many Liters of Engine Oil Should Generally Be Added?

The amount of engine oil to be added at one time depends on the type of engine. Generally, small-displacement vehicles require 3.2~3.6 liters of oil per maintenance, while larger-displacement engines need about 4.5 liters. Measure by observing the dipstick—the oil mark should be between the upper and lower lines on the dipstick, slightly above the middle line. Each car model has a different capacity, so the amount of oil added varies and should be slightly below the upper mark on the dipstick. Here is some relevant information: 1. Adding too much oil increases the resistance of the crankshaft's rotation, reduces the engine's output power, and causes excess oil to enter the combustion chamber, leading to oil burning, blue smoke emission, and increased fuel consumption. It also accelerates wear on the cylinder and piston, reducing the vehicle's lifespan. 2. If the oil level is too low, some engine components, such as the cam tappet and valves, may not receive sufficient lubrication, resulting in part wear and even severe incidents like cylinder scoring or bearing seizure.
