What are the precursors of timing chain failure?

When the timing chain becomes loose, the car may exhibit symptoms such as shaking, poor acceleration, lack of power when accelerating, and difficulty starting. Timing chain loosening is a relatively common issue. A loose chain indicates that the chain has been stretched, which can easily lead to skipping teeth, resulting in abnormal noise from the engine. Although the engine's timing chain has strong durability, it is not maintenance-free for life. Over time, with engine use, stress, and wear, the chain can stretch, creating gaps and causing the timing chain to loosen. Once signs of timing chain failure appear, prompt inspection and repair are necessary. You can use a spring scale to measure the elongation at three or more points. If the elongation exceeds the permissible length, the chain should be replaced immediately. The professional approach is to have it inspected at a repair facility by reading the crankshaft sensor and camshaft sensor. If there is an alarm indicating operational delay, there may be a risk of chain stretching, and the chain should be replaced promptly.

Where to Add Coolant for Magotan?

Antifreeze is added into the radiator. The amount of antifreeze must be between the two marked lines, neither too much nor too little. Additional information: 1. Car Radiator: The car radiator, also known as the heat exchanger, is a key component of the car's cooling system. The coolant absorbs heat in the water jacket, dissipates the heat when flowing to the radiator, and then returns to the water jacket for circulation, achieving temperature regulation. Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. 2. Antifreeze: Antifreeze has excellent properties such as preventing freezing in winter, boiling in summer, and resisting scale and corrosion all year round. For vehicles using antifreeze, never directly add tap water; distilled or deionized water should be used instead. If these are not available, cooled boiled water is better than tap water. If antifreeze is lost due to leakage, the same brand of antifreeze should be replenished, and antifreeze should be used throughout all seasons. Adding too much antifreeze can cause it to overflow from the auxiliary reservoir. Antifreeze has certain corrosive properties and may cause some corrosion to rubber components in the vehicle.

What does ETC tag detachment mean?

ETC tag detachment refers to the anti-tamper button on the back of the OBU device popping up and locking, which can occur due to: 1. Unauthorized removal or relocation of the OBU device by the user; 2. The ETC electronic tag falling off or becoming loose; 3. Device malfunction. When this happens, the ETC card cannot be used normally, and you can visit the service center where the ETC was originally processed to reactivate it. The ETC system operates through wireless communication and information exchange between the vehicle-mounted device installed on the vehicle and the antenna installed on the toll station lane. It mainly consists of an automatic vehicle identification system, a central management system, and other auxiliary facilities.

How many days is the highway free during the 2020 Mid-Autumn Festival?

Normally, highways are tolled during the Mid-Autumn Festival and do not offer free passage. However, the 2020 Mid-Autumn Festival was special because the 15th day of the eighth lunar month coincided with October 1st, overlapping with the National Day holiday. In 2020, the Mid-Autumn Festival and National Day shared an 8-day holiday period, during which highways were toll-free. The free period for highways during the 2020 National Day and Mid-Autumn Festival was from 00:00 on October 1st to 24:00 on October 8th, totaling 8 days. The vehicles eligible for free highway passage included passenger vehicles with 7 seats or fewer (including 7 seats) traveling on toll roads, as well as motorcycles permitted on ordinary toll roads. The scope of toll-free highways for airport expressways in various regions must comply with the Highway Law of the People's Republic of China and the Regulations on the Administration of Toll Roads, covering toll roads (including toll bridges and tunnels) approved according to the law. Whether airport expressways in different regions implement free passage is determined by the provincial (autonomous region or municipality) governments.

Can Guangdong Z License Plates Be Used Nationwide?

Guangdong Z license plates cannot be used nationwide. Vehicles with Guangdong Z license plates are only allowed to operate within cities in Guangdong Province. Driving beyond the boundaries of Guangdong Province is considered a traffic violation of "operating a motor vehicle without license plates." The issuance of Guangdong Z license plates itself is intended to promote exchanges in the Guangdong-Hong Kong-Macao Greater Bay Area. However, due to differences in the transportation systems of the two regions, complete unification in terms of passage cannot be achieved. Conditions for Hong Kong vehicles to apply for Guangdong Z license plates: 1. Overseas investors who have invested in Guangdong Province and have accumulated tax payments of more than 100,000 RMB within 3 years (including the application year) can apply for one mainland business vehicle license plate during the validity period of the contract; 2. Those with accumulated tax payments of more than 500,000 RMB can apply for a second license plate; 3. Those with accumulated tax payments of more than 1 million RMB can apply for a third license plate.

What happens if you fill a car designed for 92 octane with 95 octane gasoline?

If a car designed for 92 octane gasoline is filled with 95 octane gasoline for a long time, it may cause engine knocking, reduced power, increased water temperature, and metallic knocking sounds during operation. Gasoline is a mixture, and the octane rating refers to the anti-knock index of the gasoline. Strictly speaking, 92 octane and 95 octane gasoline should not be mixed. However, their chemical compositions are relatively similar, and both have strong anti-knock properties. Mixing lower octane gasoline with higher octane gasoline can lead to knocking, insufficient power, and may affect the lifespan of the spark plugs, as well as increase tailpipe emissions. Mixing different grades and types of gasoline may not cause obvious problems in the short term, but carbon buildup and fuel system blockages are long-term consequences of such mixing.
