If you notice the radiator fan running immediately after turning off the engine, you can wait for a while. This is because the water temperature in the radiator decreases slowly, and the cooling fan may continue to operate for some time before stopping when the engine is just turned off and the water temperature hasn't dropped yet. However, if the fan keeps running even after the car has completely cooled down, it might indicate a fault in the cooling fan assembly or its wiring. More information about the car's electric fan is as follows: 1. Working principle: The car's electric fan is controlled by a thermostat. When the water temperature rises to the upper limit, the thermostat activates the power supply, and the fan starts working. Once the water temperature drops to the lower limit, the thermostat cuts off the power, and the fan stops. 2. Working requirements: The electric fan motor draws a high current during operation, which demands higher specifications for the wiring used.

Can You Still Drive When the Engine Yellow Light Is On?

Whether you can continue driving when the engine yellow light is on depends on the situation: 1. If the car cannot start after the engine yellow light comes on, it may be due to a fuel pump or ignition component failure. In this case, you should not continue driving and should call for assistance; 2. If the engine yellow light is on but there are no abnormal driving symptoms, it may be due to a sensor malfunction or a false fault. In this situation, you can temporarily continue driving; 3. If the engine yellow light is on and the vehicle can still be driven but exhibits severe shaking, lack of acceleration power, or other symptoms, you should not continue driving. Continuing to drive may worsen the fault, damage the engine, or cause other failures. Instead, you should call for help and wait for support.

How to Check the Front and Back of a Tire?

Methods to check the front and back of a tire: 1. For most tires, the side with the production date should face outward; 2. Observe whether there are two dots on the side of the tire—one red and one yellow. The red dot is solid, while the yellow one is hollow. The side with these dots should face outward; 3. Determine by the letters, though this method is not fixed as it varies by brand. For example, Dunlop tires have the word 'outside' on the outward-facing side, while other brands may not have these letters. Some tire brands may have the word 'inside' on the inner side.

What is the rhyme for parallel parking?

The rhyme for parallel parking is: 1. When the right rearview mirror no longer sees the right angle, turn the steering wheel one full turn to the right; 2. When the left rearview mirror sees two-thirds of the side line, turn the steering wheel one full turn to the left until the left rear wheel crosses the line, then turn the steering wheel fully to the left; 3. When the seam of the left hood aligns with the yellow straight line, step on the brake; 4. When the front of the car crosses the line, turn the steering wheel one full turn to the right to correct the position, then drive straight. Parallel parking is becoming increasingly common in cities, especially when regular parking spaces are in short supply. Many areas have converted the sides of streets into parallel parking spaces. In the past, parallel parking was practiced using four poles placed on the ground to symbolize the four corners of a garage. One of the criteria for successful parking was whether the vehicle could enter the garage smoothly without touching these four poles. After the implementation of new traffic regulations, parallel parking no longer uses poles; instead, all boundaries are marked with lines on the ground.

How to Determine a Clogged Catalytic Converter with One Trick?

A method to determine a clogged catalytic converter with one trick is: A clogged catalytic converter can cause the vehicle's engine warning light to illuminate, poor exhaust flow, reduced power, engine shaking, frequent stalling, and is often accompanied by increased fuel consumption and excessive exhaust emissions. The catalytic converter is a crucial component of a car, installed between the engine exhaust manifold and the muffler. It transforms harmful gases like CO, HC, and NOx, produced by engine combustion, into harmless carbon dioxide, water, and nitrogen through the oxidation and reduction reactions facilitated by the ceramic honeycomb structure and precious metals inside the catalytic converter. Since this converter can simultaneously convert the three main harmful substances in exhaust gases into harmless ones, it is called a three-way catalytic converter.

What to Do When the Front Windshield Fog Cannot Be Blown Away?

If the fog on the front windshield cannot be blown away, it may be due to a leak in the glass interlayer seal, allowing water vapor to enter the windshield interlayer. Specific details are as follows: 1. Solution: Identify the leak in the windshield seal, blow out the water vapor from the windshield, and reseal the windshield. 2. Cause of fogging: Fogging on the front windshield can occur on the inside or outside. Whether internal or external, the main reason is that the glass surface temperature is lower than the air temperature, and the air humidity is relatively high. When warm, humid air encounters the cold front windshield, it releases heat and condenses, forming fog.
