What does the handwritten tag on a new car key mean?

The tag on the new car key is the factory password for the vehicle key, used to encode new keys. Additional information: 1. Spare key: High-end cars have both master and spare keys, with the spare key unable to open the trunk and glove box. 2. Key code: After purchasing a new car, be sure to keep the hand tag that comes with the key. This is the key code for the car, and if the key is lost, the key code can be used to make a new one. 3. Key material: High-quality keys are made of alloy, while ordinary ones are made of mixed copper. In terms of usage, the lifespan of a high-quality key is 5-6 times that of an ordinary key, and the wear on high-quality keys and lock cylinders is generally synchronized. 4. Trunk usage: High-end cars have two methods to open the trunk—one using the key and the other using an electric switch. Always ensure both methods work; if one fails, repair it as soon as possible. Never use the key to push against the lock cylinder to open the trunk, as this can easily break the key inside the lock. Also, avoid closing the trunk with the key inserted in the lock cylinder, as this can also easily break the key.

What is Refrigerant Oil?

Refrigerant, commonly known as Freon, is a working fluid used in refrigeration and air conditioning systems to transfer heat energy and produce cooling effects. It can be classified by working method into primary refrigerant and secondary refrigerant, and by material properties into natural refrigerant and synthetic refrigerant. The main function of refrigerant is to transfer heat energy and produce cooling effects in refrigeration and air conditioning systems. Below is relevant information: 1. Refrigerant composition: It consists of polyester-based synthetic oils (such as polyalkylene glycol). Since nitrile rubber is incompatible, polybutadiene nitrile rubber is used as a sealing component. Its characteristics are colorless, odorless, non-toxic, non-flammable, and non-explosive. Currently, R134a refrigerant is widely used. R134a does not damage the atmospheric ozone layer but still has a certain greenhouse effect and is currently one of the substitutes for R12. 2. Refrigerant replacement: There is no fixed time cycle for adding or replacing refrigerant. Whether it needs to be replaced or added mainly depends on the state of the air conditioning refrigeration. The simplest way to evaluate the state of refrigeration is to measure the temperature of the air conditioning outlet, which is generally between 5 to 10 degrees Celsius and considered normal, with slight variations among different vehicle models. After eliminating reasons such as heat dissipation or refrigerant leakage, the refrigerant can be replaced. Additionally, after repairing or replacing components of the air conditioning system, the refrigerant may also be replaced to ensure the cooling effect of the air conditioning.

What should I do if there is abnormal noise in the Wuling Rongguang intake manifold?

Check whether the intake manifold gasket is damaged and leaking. Check each vacuum tube for leaks. More relevant information is as follows: 1. Function: It distributes the combustible mixture provided by the carburetor to each cylinder. The function of the exhaust manifold is to collect the exhaust gas after the work of each cylinder and send it to the exhaust pipe and muffler, and then discharge it into the atmosphere. 2. Casting: The intake manifold and exhaust manifold are usually made of cast iron. The intake manifold is also suitable for aluminum alloy castings. The two can be cast as a whole or separately. 3. Fixing: The exhaust manifold is fixed with studs to the cylinder block or cylinder head, and the joint is equipped with an asbestos gasket to prevent leakage. The intake manifold is installed with a carburetor with a flange and the exhaust manifold is connected to the exhaust pipe.

What are the common effects of a car PCV valve?

Car PCV valve is a valve that controls the reuse of exhaust gases in the crankcase. If the car PCV valve is faulty, the following symptoms may occur: 1. Engine shaking, unstable idle: A large amount of white smoke is emitted from the exhaust pipe. 2. Causes corrosion in the crankcase: Accelerates wear and shortens the engine's lifespan. 3. Makes the engine difficult to start: Symptoms include idle shaking, poor acceleration, and excessive oil loss. 4. Prone to sludge buildup leading to blockage: Blockage increases pressure in the crankcase, causing oil vapor and exhaust gases to flow back into the air filter, contaminating it.

What are the consequences of not engaging the handbrake when the car is in P gear?

Prolonged practice can cause some harm to the vehicle. More information about not engaging the handbrake when the car is in P gear is as follows: 1. P gear: Also known as the parking gear. When the vehicle is in P gear, the parking lock mechanism will lock the transmission output shaft, meaning the gears inside the transmission cannot rotate. 2. Principle of P gear: When using P gear to park, the car's gear engagement device directly hooks onto the transmission gear, causing the transmission to stop output immediately. This is equivalent to locking the transmission's drive wheel, so the car naturally stops due to lack of drive. However, if parked for a long time, most of the parking resistance comes from the transmission, which may shorten the lifespan of the transmission lock mechanism over time. Especially when parked on a slope, the harm to the transmission can be even greater. Moreover, in this parked state, when starting again at low speed, the car's startup becomes relatively difficult, and some noise may even be heard. These phenomena indicate that the car's transmission is gradually being damaged.
