What Needs to Be Done for Used Car Refurbishment?

Clean the interior and exterior thoroughly before putting it up for sale. The following are precautions for used car transactions: 1. Verify the identity of the used car: When purchasing a car, carefully check the ID card, original vehicle invoice, vehicle purchase tax certificate, vehicle license, road maintenance fee certificate, annual inspection certificate, and insurance policy to ensure there are no issues. If the documents are incomplete, you may encounter numerous hassles when handling related procedures later. There have been precedents in this regard, so be extremely careful. Additionally, verify the engine number and chassis number to confirm the vehicle's identity and avoid being deceived. 2. Check if the odometer has been tampered with: To fetch a higher price, dealers often roll back the mileage. In reality, mileage is just one factor in assessing a car's condition. The actual condition can be determined by inspecting parts like the engine, and the odometer reading is not the sole determinant of the car's price. 3. Don’t overlook repainting: Check for any peeling paint, fresh marks on the surface, or excess paint around the exhaust pipe, trim, and windows. If found, it indicates the car has been refurbished, possibly due to scratches or damage, which can serve as one of the criteria to judge its condition.

Can Accident Vehicles Be Insured?

Accident vehicles can indeed be insured. Here is relevant information about accident vehicles: Definition of an accident vehicle: First, observe whether the gaps between body panels are uniform and consistent, then check if the side body lines are smooth. If noticeable misalignment in the waistline is found, it can be concluded that the vehicle has been involved in a collision, and a relatively severe one at that. Hazards of accident vehicles: Vehicles involved in major accidents typically leave traces on the frame that are difficult to fully repair; once a severely damaged vehicle is flooded, its electrical circuits and components can suffer very serious damage.

Is pressing the right corner during a right-angle turn due to turning the wheel too early or too late?

Pressing the line during a right-angle turn depends on the situation: 1. Taking a left turn as an example, if you turn the steering wheel too early before entering the right angle, the left wheel will press against the right angle. To avoid pressing the right angle, you must not turn the steering wheel all the way. Wait until the rear wheel passes the right angle before turning the steering wheel all the way. In this case, the right front wheel will definitely press against the right line after the turn; 2. Still taking a left turn as an example, if you are very close to the left line when turning, you must not turn the steering wheel too early. If you turn too early, the car will press against the right angle. If you turn too late, the situation mentioned in the question will occur. Therefore, for a left turn, you should stay closer to the right side; 3. Taking a left turn as an example, if you are not very close to the left line but are driving closer to the right side, turning the steering wheel too late will also cause the right line to be pressed after the turn.

What are the symptoms of an air leak in a car engine?

An air leak in a car engine can result in increased exhaust emissions and reduced acceleration power. Here is additional information about engine air leaks: 1. Causes of air leaks: Clogged air filters or poor working conditions can allow sand, dust, and other particles to enter the valve guides, causing wear on the valve stems and guides. This leads to uneven wear between the valve heads and seats, compromising the seal and resulting in air leaks. Valve heads located in the upper part of the combustion chamber are constantly exposed to high-temperature, high-pressure gas, making them prone to erosion and leaks. Incorrect valve clearance adjustment, either too small or nonexistent, can cause the valve train components to expand when heated during operation. This may result in the rocker arm head pressing against the valve stem end, preventing the valve from closing properly and causing leaks. 2. Solutions: During maintenance, thoroughly clean carbon deposits in the cylinder, especially on the valve stems, valve seats, and seat openings. Carefully inspect the number of erosion spots and the width of the contact band on the valve cone surface. If the contact band is too wide or there are many erosion spots, use a reamer to adjust and lap the surface. If the valve seat ring is damaged, the valve head is warped, or the stem is bent, replace the valve or valve seat ring. If the issue is due to insufficient valve clearance, readjust the clearance to meet the required specifications.

What brand of spark plugs does the Roewe 350 come with from the factory?

The Roewe 350 comes with NGK double platinum PFR6Y spark plugs from the factory. The replacement cycle for this type of spark plug is 40,000 kilometers. Spark plugs are a crucial component of a gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and produce a spark, thereby igniting the combustible mixture in the cylinder. If a spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of the spark plug, such as blistering at the top, damage, or melting and erosion of the electrodes, indicates that the spark plug is destroyed and should be replaced. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are cleaned thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the order of the ignition sequence and secure the cover.

Is it necessary to replace the oil drain plug during car maintenance?

It is not always necessary to replace the oil drain plug during car maintenance. The specific circumstances are as follows: 1. Depending on the vehicle model: Some vehicle models require the oil drain plug to be replaced every time the oil is changed. 2. Reason for replacement: The main purpose of replacing the oil drain plug with a new one during each oil change is to prevent oil leakage. Relevant information about the oil drain plug is as follows: 1. Oil pan drain plug: This is a screw located at the bottom of the engine oil pan. 2. Function: When the engine requires an oil change during maintenance, this screw is loosened to drain the old oil from the engine. After tightening the screw, new oil is added through the engine's filling port.
