How to Check the Manufacturing Date of Car Tires?

Locate the DOT marking on the tire sidewall. The last four digits after DOT indicate the tire's production date. More details about tire date codes are as follows: 1. The date code consists of four digits in "AABB" format. The first two digits "AA" represent the week of the year, while the last two digits "BB" indicate the year. 2. For example, if the code reads "3513" after DOT, it means the tire was manufactured in the 35th week of 2013. If you can't find the date code after DOT, it might be on the other side of the tire. If DOT is completely missing, the tire might be mounted inside out with the date code facing inward.

Can a clogged car carbon canister be cleaned?

A clogged car carbon canister can indeed be cleaned. Here are two suggestions for dealing with a clogged car carbon canister: 1. If the carbon canister has accumulated dust, it can be cleaned in this case. 2. If there is gasoline inside the carbon canister or if the carbon canister is damaged, it is recommended to replace it directly. Below is some relevant information about the carbon canister: (1) The primary function of the carbon canister is to store gasoline vapors. The canister contains activated carbon particles that can absorb gasoline vapors. However, over time, the carbon canister may become clogged, which can affect the normal operation of the car. (2) To better prevent clogging of the carbon canister, during regular refueling, if you want to fill the fuel tank completely, stop at the first click of the fuel pump. Do not continue to add fuel, as this can easily force gasoline into the carbon canister.

How to Determine Running a Red Light When Turning Left?

Running a red light is determined by capturing three photos via electronic cameras: A photo showing the vehicle crossing the intersection stop line, including the red traffic light and license plate number. A photo showing the vehicle completely passing the stop line, including the red traffic light and license plate number. A photo showing the vehicle continuing to move, with a comparison to check if the vehicle's position has changed, including the red traffic light and license plate number. Capturing these three photos confirms that the vehicle ran a red light. The act of running a red light is clearly defined in the "Road Traffic Safety Law". Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage; driving through an intersection during a red light constitutes the traffic violation of running a red light. To avoid running a red light, consider the following points: First look at the arrow light, then the circular light: Currently, there are two types of indicator lights: arrow traffic lights and circular traffic lights. When arrow lights are present, first observe the arrow light and then the circular light to avoid running a red light. Note: When encountering a circular red light, right turns are permitted. However, if the right-turn arrow is red, right turns are prohibited, and violating this will be penalized as running a red light. Brake in time: When the red light turns on, ensure the front of the vehicle does not cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture it, resulting in a penalty for running a red light. If the front wheels have just crossed the stop line when the light turns red, do not proceed through the intersection; wait for the green light. Check the green light countdown before proceeding: When the green light flashes, if there is a countdown, use it to make a judgment. If there is no countdown, and the vehicle is close to the intersection with sufficient speed, proceed to avoid running a red light due to untimely braking. If the speed is slow and the vehicle is far from the intersection, brake immediately to stop and avoid running a red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states regarding motor vehicle and non-motor vehicle signal lights: When the green light is on, vehicles are permitted to proceed, but turning vehicles must not hinder the passage of straight-moving vehicles and pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to proceed. When the red light is on, vehicles are prohibited from proceeding. At intersections without non-motor vehicle or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signal lights. When the red light is on, right-turning vehicles may proceed if they do not hinder the passage of other vehicles and pedestrians. Running a red light is not considered illegal under the following circumstances: Yielding to special vehicles: Yielding to ambulances, fire trucks, and other special vehicles. If captured by surveillance cameras while yielding, manual review will not record the act as running a red light. Even if recorded, you can apply for reconsideration at the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic lights. Blurred evidence photos may result in accidental red-light running, for which traffic police will not impose penalties. Emergency situations: Transporting a critically ill patient to the hospital may involve running multiple red lights, quickly exhausting the 12-point penalty limit. After delivering the patient, provide proof from the hospital or the rescued individual to the traffic police for verification. If confirmed, the violation records can be cleared. If possible, calling an ambulance is advisable to avoid accidents from running red lights. Traffic police direction: During peak hours, traffic police may temporarily direct traffic at key intersections. Drivers should follow the gestures of the traffic police.

What to Do When Water Drips from the Exhaust Pipe After Parking?

Water dripping from the exhaust pipe after parking is a normal phenomenon indicating complete combustion of gasoline. To some extent, it reflects that the car engine is in good working condition and the gasoline is burning efficiently. However, excessive water dripping is not ideal, as too much water can damage the oxygen sensor in the catalytic converter and reduce the vehicle's power performance. If abnormal water dripping occurs from the exhaust pipe, inspection and repair are necessary. Below are some considerations regarding abnormal water dripping from the exhaust pipe: 1. Check if the coolant tank is leaking. It is possible that the engine's coolant tank is leaking, allowing coolant to enter the combustion chamber and causing water to drip from the exhaust pipe. 2. Check if the coolant tank frequently runs low. 3. Inspect whether the engine's cylinder head gasket is properly sealed.

Should Freon be added to the car air conditioning system from the low-pressure or high-pressure side?

Freon can be added from either the low-pressure or high-pressure side. More information about adding Freon to car air conditioning systems is as follows: 1. There are two methods for adding Freon to car air conditioning systems. High-pressure side filling: Suitable for filling after leak detection and vacuuming, the compressor must not be turned on, the engine must be stopped, and the refrigerant tank must be inverted; Low-pressure side filling: Gas is added, characterized by slow filling speed, usually suitable for supplementing refrigerant. 2. After filling is completed, close the low-pressure manual valve on the manifold pressure gauge and the injection valve on the refrigerant tank, stop the engine, and quickly remove the manifold pressure gauge from the compressor to avoid excessive refrigerant leakage.
