What are the solutions for abnormal noise when the car is in R gear?

How to align the timing chain of Changan 473 engine?

Align the crankshaft according to the mark on the crankshaft timing pulley, generally requiring the No. 1 cylinder piston to be at the top dead center position; align the two camshafts separately for the dual camshafts. The timing chain of the Changan Star belongs to the engine cover and bracket category. The timing chain replaces the timing belt, but their principles are the same—one is on the outside, and the other is on the inside of the machine, both connecting the camshaft and the crankshaft for coordinated movement. The following are the precursors of timing chain failure: 1. Abnormal noise: During driving, listen to the engine sound. If there are occasional "clicking" friction sounds or a noticeable change compared to the usual sound, it indicates a timing chain failure, and it is recommended to check and replace it promptly. 2. Increased fuel consumption: After driving a certain mileage, the car may experience varying degrees of increased fuel consumption, which may be caused by timing chain failure. 3. Decreased power output: The phenomenon of decreased power output in the car is largely caused by the engine and related component configurations. Once the timing chain fails, it will restrict the movement of the cylinders, affecting the air intake and exhaust functions.

Will the insurance company compensate if the car is submerged in an extraordinary rainstorm?

Insurance companies will compensate for vehicle submersion caused by extraordinary rainstorms. Below are the specific details of insurance claims: 1. Motor Vehicle Damage Insurance: During the insurance period, the insurer is responsible for compensating the insured vehicle's losses caused by collisions, overturning, fire, explosion, falling objects, collapse, lightning, storms, tornadoes, rainstorms, floods, ground collapse, ice collapse, cliff collapse, avalanche, hail, mudslides, landslides, etc., according to the insurance contract. Expenses incurred after the vehicle is submerged, such as rescue fees, cleaning fees, electrical losses, and interior damage, are all covered under the motor vehicle damage insurance, and the insurance company should compensate accordingly. 2. Engine Water Immersion Damage Insurance: This refers to an additional insurance purchased by the car owner specifically for the engine, which can only be purchased after having motor vehicle damage insurance. During the insurance period, the insurer is responsible for compensating for direct engine damage caused by water entering the engine while the insured vehicle is in use.

What does used car preparation mean?

Used car preparation refers to the process of conducting a comprehensive inspection of the vehicle's documentation and overall condition. Below are the relevant details about used car preparation: 1. Re-establishing the used car records: Creating an information file for the used car. Some used cars entering the market may already be in a state where the insurance has expired or there is no insurance at all, a condition commonly referred to as "uninsured." Some may also lack complete maintenance records. 2. The significance of used car preparation for both buyers and sellers: From the perspective of the original owner, preparation might simply involve washing the car and organizing the vehicle's documents, which could be considered as completing the task. However, for the next owner, this approach may seem somewhat irresponsible. 3. The content of used car preparation by dealers: Reputable used car dealers will immediately start creating a new maintenance record for the vehicle after acquisition. The main tasks include checking whether the vehicle has been involved in any accidents, assessing the extent of damage caused by any accidents, conducting a thorough inspection and maintenance of the vehicle, and replacing or repairing any necessary parts. Finally, the vehicle undergoes a detailed cleaning.

Right-angle turn: Before entering a right-angle turn, you can slow down or stop to straighten the wheels or align the car body, staying as close to the right side line as possible. 5. Curve driving: Don't turn the steering wheel too sharply when driving through curves; try to take a wider path after entering the curve. 6. Reverse parking: Maintain idle speed throughout the reverse parking process, accurately judge your position, control key points and timing, and know how to make minor adjustments when deviations are noticed through the mirrors.

How to Control Speed While Driving?

Driving speed is controlled by depressing the clutch and applying the foot brake. Here are detailed instructions on speed control: 1. Technique: Speed control can be practiced by driving in a straight line while continuously operating the clutch and foot brake. The clutch should be depressed quickly and released slowly, with minimal pedal movement at all times. For parallel parking and curve driving, lightly tapping the foot brake can effectively reduce speed. 2. Precautions: Always pay close attention to traffic signs along the route and strictly adhere to their regulations. Adjust speed flexibly according to road and driving conditions.
