What are the symptoms of an overheating engine?

Symptoms of an overheating engine: 1. The coolant temperature gauge needle reaches the red zone; 2. During driving, you may feel the engine lacks power when accelerating or even stalls; 3. Opening the engine hood may reveal coolant spraying from the overflow tank or boiling in the expansion tank; 4. Cooling system hoses swelling like sausages; 5. A burning rubber smell. Causes of engine overheating: 1. Insufficient coolant level; 2. Clogged radiator; 3. Loose fan belt, resulting in insufficient airflow through the radiator; 4. Excessive concentration of antifreeze coolant. Normal operating temperature ranges for automotive engines: Passenger cars typically operate between 95-98°C; Commercial vehicles between 90-95°C; Sports cars can reach 105-115°C; Race cars operate around 130°C.

What Causes Car Vibration at High Speeds?

Reasons for car vibration at high speeds: 1. Ignition system failure: Issues with spark plugs, high-voltage wires, or ignition coils can lead to poor ignition system performance, triggering the engine warning light accompanied by vibration. 2. Overly rich air-fuel mixture in the cylinders: This may cause knocking and vibration. 3. Abnormal fuel supply pressure: This can also result in car vibration. 4. Faulty idle control valve or wiring. If the engine warning light flashes and the car shakes, it is recommended to stop immediately for safety, avoid continuing to drive, and call a 4S shop or professional auto repair shop for assistance, requesting a tow truck or waiting for rescue.

Can You Drive a Short Distance with a Flat Tire?

Whether you can drive a short distance with a flat tire depends on the type of tire. If it's a regular car tire, you should not drive even a short distance when it's flat. However, if it's a run-flat tire, you can drive a short distance—or even a longer distance—with it flat. Run-flat tires are designed to handle such conditions. In contrast, driving on a flat regular tire will cause the sidewall to be crushed, which is the weakest and most dangerous part of the tire. Friction in this state can easily break the internal fabric layers, creating a significant safety hazard. Severe cases may even deform the wheel rim, requiring replacement if the damage is extensive.

How to Turn Off All Vehicle Lights?

Method to turn off all vehicle lights: Rotate the light control knob to the OFF position. For some models, the off position is marked as O, while others have a button that can be pressed to turn off the lights. Some models have the control on the light stalk, where rotating the stalk will turn off the lights. Low beam headlights are used when driving in urban areas at night. On one hand, city roads are usually well-lit by streetlights, eliminating the need for high beams to illuminate distant road surfaces—seeing the road conditions directly ahead is sufficient. On the other hand, urban roads have heavy traffic, and using high beams not only dazzles oncoming drivers during encounters but also affects the visibility of pedestrians on both sides of the road. High beam headlights are more suitable for use in rural areas or on roads without street lighting. However, during encounters with other vehicles, you should switch back to low beams to avoid dazzling the other driver.

Is Replacing a Release Bearing Considered a Major Overhaul?

No. The following is relevant information about the release bearing: Introduction: The clutch release bearing is installed between the clutch and the transmission. The release bearing housing is loosely fitted on the tubular extension of the transmission's first shaft bearing cover. A return spring ensures that the shoulder of the release bearing always presses against the release fork and retracts to the rearmost position, maintaining a gap of approximately 3-4mm with the end of the release lever (release fingers). Performance: The clutch release bearing should move smoothly without sharp noises or sticking. Its axial clearance should not exceed 0.60mm, and the wear on the inner race should not exceed 0.30mm. Usage Precautions: Ensure the clutch release levers are properly leveled, and the return spring's elasticity meets specifications. Adjust the free travel to the required range (30-40mm) to prevent it from being too large or too small.
