How to Identify the Production Year of Car Glass?

Methods to identify the production year of car glass: 1. The glass year is composed of black dots and numbers. If small black dots precede the number, it indicates production in the first half of the year, with the month calculated by subtracting the number of dots from 7. If the number precedes the small black dots, it indicates production in the second half of the year, with the month calculated by subtracting the number of dots from 13. 2. The glass year may also consist of black dots, a number, and asterisk-shaped black dots. The number represents the last digit of the year, the count of small black dots indicates the quarter, and the number of asterisks following represents the specific month within that quarter. The production date of the glass should predate the vehicle's production date. Knowing how to read the glass production date helps determine if the glass has been replaced. If the glass production date is later than the vehicle's production date, it means the glass was replaced afterward. The vehicle's production date is usually found on the vehicle's nameplate located on the B-pillar.

What is the normal time frame for vehicle delivery after placing an order?

After completing the car purchase procedures, it is generally normal to take delivery of the vehicle within one month. For some popular models or customized imported cars, the delivery time may extend up to six months. The precautions and procedures for vehicle delivery are as follows: Precautions for vehicle delivery: When taking delivery of the vehicle, check the relevant documents of the new car, including the purchase invoice, certificate of conformity, vehicle consistency certificate, vehicle registration certificate, warranty certificate, vehicle manual, and new car delivery confirmation form. For the exterior, inspect the paint, production date of the window glass, tires, trunk, and engine. For the interior, focus on checking the car's functions, such as lights, windows, rearview mirrors, dashboard, air conditioning, etc. 4S store vehicle delivery process: Determine the car you want to buy based on your needs. Then place an order. If there is no stock, you need to sign a purchase contract and pay a deposit, after which the 4S store will place an order with the manufacturer. Once the car arrives, go to the 4S store to pay the full amount and take delivery of the vehicle.

Is it necessary to clean carbon deposits in the cylinder at 40,000 kilometers?

It is necessary to clean carbon deposits in the cylinder at 40,000 kilometers, as it has reached the cleaning cycle. The cleaning cycle for carbon deposits in the cylinder and the effects of excessive carbon deposits are as follows: Cleaning cycle for carbon deposits in the cylinder: Generally, 4S shops recommend car owners to perform maintenance every 10,000 kilometers. Owners can adjust this based on their driving conditions. If driving frequently on highways, the interval can be extended to 30,000-40,000 kilometers, while other owners can clean it at 20,000-30,000 kilometers. Effects of excessive carbon deposits: Excessive carbon deposits can alter the original structural parameters of the engine, reduce engine power, and increase fuel consumption. In severe cases, it may cause engine knocking, abnormal acceleration noises, and damage to pistons and crankshafts. Carbon deposits accumulate layer by layer, becoming thicker and leading to a vicious cycle. In extreme cases, it may even block half of the intake valve, ultimately resulting in the engine burning oil and requiring major repairs.

Does Car Tire Pressure Decrease on Its Own?

Car tire pressure will indeed decrease over time. All tires require periodic inflation, especially those filled with air, as the pressure fluctuates significantly with temperature changes. As long as the pressure doesn't drop sharply within a short period, this is normal. Hazards of low tire pressure: Increased friction coefficient with the road surface, leading to higher fuel consumption; Heavier steering wheel and a tendency to drift, which are unfavorable for driving safety; Increased movement of various parts of the tire, causing abnormal heat due to excessive rolling; Reduced functionality of the cords and rubber, leading to delamination or cord breakage, excessive friction with the rim, resulting in damage to the bead area and abnormal wear; Exponentially increased friction between the tire and the ground, rapid rise in tire temperature, softening of the tire, and a sharp decrease in strength. High-speed driving may lead to tire blowouts; Increased deformation of the tire body, prone to cracking on the sidewalls, along with flexing movements, leading to excessive heat, accelerated rubber aging, fatigue of the cord layers, cord breakage, and increased tire contact area, accelerating shoulder wear.
