A faulty thermostat can lead to multiple issues. Here are the related scenarios when a thermostat fails: 1. Coolant Leakage: The thermostat is installed at the junction where two circulation systems' pipelines connect. The presence of an interface in the water channel at this location poses a risk. Despite the thermostat being equipped with seals, coolant leakage can still occur. 2. Engine Overheating: When the thermostat gets stuck in the position that closes the major circulation loop, even if the coolant temperature can soften the paraffin, the major circulation still cannot be opened. In this situation, the coolant itself cannot dissipate heat, quickly leading to engine overheating.

What are the symptoms of a bad axle shaft?

Symptoms of a bad axle shaft: 1. Abnormal noises on bumpy roads, unstable vehicle, swaying left and right, brake deviation, and steering failure; 2. Excessive play in the axle shaft, making it prone to breakage under impact loads. High-speed driving may cause the wheel to fall off, and an out-of-round wheel hub can lead to inaccurate dynamic balance, manifesting as steering wheel vibration at high speeds. If the axle shaft of the rear wheel in a front-wheel-drive vehicle is damaged, there will only be metal friction sounds or hard metal collision noises. The axle shaft, also known as the drive shaft, is the shaft that transmits torque from the gearbox reducer to the drive wheel. Each end of the shaft has a universal joint connected via splines on the universal joint to the reducer gear and the inner ring of the wheel hub bearing.

How to Complain About Prolonged Highway Traffic Jams?

If the prolonged highway traffic jam is caused by an accident, you can call the traffic police hotline 122 to file a complaint; if the jam is due to excessive vehicles, it is considered an act of force majeure, and the highway management is not liable, meaning there is no way to file a complaint. If no one is managing the highway traffic jam, you can address the situation in the following ways: 1. Expand your field of vision—during a traffic jam, there's no need to align directly with the car in front; slightly offset to the left to keep an eye on the traffic situation. 2. Maintain an appropriate distance from the car ahead. 3. Gently press the accelerator to steadily follow the flow. 4. Before the car in front comes to a complete stop, maintain a slow and steady speed, keep a safe distance, and be cautious of rear-end collisions.

Will driving below 60 km/h on highways result in penalty points?

Driving below 60 km/h on highways will result in penalty points. In China, the minimum speed limit on highways is generally 60 km/h, except for special road conditions or weather circumstances. When driving passenger vehicles on highways, the speed should not exceed 120 km/h, while other motor vehicles should not exceed 100 km/h. Highways, abbreviated as expressways, are roads specifically designed for high-speed vehicle travel. The road surface consists of three main parts: the main carriageway, ramps, and auxiliary lanes. The main carriageway, also known as the traffic lane, is divided from left to right into overtaking lanes, fast lanes, and slow lanes depending on the number of lanes. Highways can accommodate speeds of 120 km/h or higher, with a width of four or more lanes. A median separator is installed in the middle, and the road surface is paved with high-grade asphalt concrete or cement concrete, equipped with complete signs, markings, signals, and lighting devices.

How long is the vehicle release period?

Vehicle release and archiving typically takes 1 to 3 days, with most regions currently able to complete the process on the same day. Documents required for mortgage cancellation registration: Original and photocopies of identity documents for both the vehicle owner and mortgagee. For mortgage registration, the original or photocopies of the principal contract and mortgage contract legally executed by the vehicle owner and mortgagee must also be provided. For vehicles released from mortgage through court mediation, ruling, or judgment, the original and photocopies of the court-issued "Mediation Agreement," "Ruling," or "Judgment" must be provided along with the corresponding original "Notice of Assistance in Execution." For proxy registration, the agent's identity documents and original legally binding written powers of attorney separately issued by the vehicle owner and mortgagee must also be provided. Important notes regarding vehicle release periods: According to relevant regulations, vehicle mortgages that are not registered have no legal effect. The same applies to contracts. Therefore, disputes may lead to creditor issues. During the mortgage period, the mortgagor may transfer the mortgaged vehicle at any time without the mortgagee's consent, and other creditors may also demand that the debtor use the vehicle to settle debts.

What are the gear shifting techniques for heavy trucks?

The gear shifting techniques for heavy trucks are: 1. The double-clutch method, which involves pressing the clutch once when disengaging the gear and pressing it again when engaging the gear, requiring proper coordination and quick speed; 2. The single-clutch method, where the clutch is not used when disengaging the gear but is pressed when engaging the gear, also requiring proper coordination. This method requires practice to disengage the gear without using the clutch; 3. The clutchless method, which also requires practicing disengaging the gear without the clutch. When shifting, engage the gear when the engine's revving sound is about to finish, i.e., when the revving speed drops to the lowest point.
