What Causes High Engine Temperature Alarm?

Reasons for high engine temperature alarm: Insufficient coolant: Possible causes include insufficient engine coolant, faulty water temperature sensor or gauge, and prolonged low-speed, high-load driving during hot seasons, which can also lead to high temperatures. Overheating: When encountering a high water temperature alarm, first reduce speed and pull over to the roadside. Do not rush to turn off the engine, as excessive heat can cause components like pistons, cylinder walls, and the crankshaft to overheat, thinning the oil and reducing lubrication. Engine seizure: If the engine is turned off at this point, the parts are still in an expanded state with minimal clearance between them. Shutting down can cause soft metals to detach, and in severe cases, lead to engine seizure. Therefore, after noticing overheating, do not immediately turn off the engine; instead, keep it idling to cool down as much as possible. Blockage: When cooling, avoid splashing cold water on the engine to prevent sudden thermal contraction and potential blockage. The correct method is to wear gloves, place a folded wet cloth over the radiator cap, and gently loosen it slightly to allow steam to escape slowly. Once the radiator pressure drops, add cool water or antifreeze.

What does misfire mean?

In fact, misfire refers to engine cylinder misfire. Definition of misfire: Engine misfire means that during normal operation, one or several cylinders fail to combust properly. The air-fuel mixture in these cylinders cannot be ignited, and the unburned mixture is expelled into the exhaust manifold and then enters the catalytic converter. Since the temperature inside the catalytic converter is extremely high, the unburned mixture will combust there. Serious consequences of misfire: Severe misfire can cause the catalytic converter to overheat and burn out (typically, catalytic converters can withstand temperatures up to 1200 degrees Celsius, and under normal engine operation, the temperature does not exceed 920 degrees Celsius). Checking for misfire is simple: after starting the engine, let it idle and observe whether there is abnormal shaking during operation, and whether this shaking has a clear periodic pattern.

Should You Use the External Air Circulation When Running the Car AC in Summer?

You should use the external air circulation when running the car AC in summer. The correct way to turn on the car AC in summer is: first turn on the external air circulation to expel the hot air inside the car. After feeling a significant drop in the cabin temperature, you can then switch to internal air circulation. Internal Air Circulation System: The air exchange channel between the inside and outside of the car is closed. When the fan is off, the airflow inside the car does not circulate. When the fan is on, the inhaled airflow comes only from inside the car, forming an internal airflow circulation. External Air Circulation System: The external air circulation mode uses the fan to draw air from outside the car into the cabin. The air blown by the fan comes from outside the car. Even if the fan is off, airflow is still drawn into the car while driving, replenishing fresh air inside the car.

What does it mean when there is a loss of pressure in the rear tire?

If your car displays a warning for a loss of pressure in the right rear tire, it indicates that the tire pressure in the right rear tire is abnormal and requires calibration. Only vehicles equipped with a tire pressure monitoring system (TPMS) will show this alert. TPMS can promptly reflect tire conditions, eliminate potential safety hazards, and extend tire lifespan. There are three commonly used methods for tire pressure monitoring: Direct Tire Pressure Monitoring: Direct TPMS uses pressure sensors installed in each tire to directly measure tire pressure. The pressure data is transmitted wirelessly from inside the tire to a central receiver module, which then displays the pressure readings for each tire. The system automatically alerts the driver if the tire pressure is too low or if there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that tire to become smaller, making it rotate faster than the other wheels. By comparing the differences in rotational speed between the tires, the system monitors tire pressure. Indirect TPMS essentially relies on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS) Overview: This system combines the advantages of both the direct and indirect systems. It equips direct sensors in two diagonally opposite tires and includes a 4-wheel indirect system. Compared to using only a direct system, this hybrid approach reduces costs and overcomes the limitation of indirect systems, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time pressure data for all four tires as effectively as a full direct system.

Is the left side of the left garage too wide due to early or late steering?

Left side being too wide when reversing into the left garage is caused by late steering. Below are relevant introductions about reversing into a garage: 1. Evaluation criteria: Not following the prescribed route or sequence will result in failure. Exceeding 210 seconds to complete reversing into the garage will result in failure. 2. Techniques: Control the driving speed by using 1st gear or reverse gear at idle speed throughout; maintain the same speed as when starting. Control the driving route. During the test, the car's driving route mainly depends on the speed of steering wheel rotation and driving speed. When reversing, accurately observe the sidelines and promptly correct the direction to ensure the car enters the garage straight.

What Grit Sandpaper Should Be Used for Car Polishing?

When polishing a car, use 320-grit sandpaper for dark-colored vehicles and 400-grit for newer light-colored cars. Introduction to Car Polishing: Car polishing involves using a polishing machine with a polishing pad and abrasive compound to evenly grind the car's paint surface. It primarily relies on the cutting force of the polishing pad and the fine particles in the abrasive compound to heat and soften the paint, allowing the surrounding paint to fill in scratches. This process results in a smooth and glossy finish that hides imperfections. Precautions for Car Polishing: If your car requires polishing, it is recommended to visit a professional auto detailing shop. Achieving good results without a polishing machine is difficult, and improper operation can damage the car's paint surface.
