No. The task of the cooling fan is to dissipate all the heat inside the engine through the cooling cycle. If the fan stops working, the engine's cooling is affected, and continuing to drive may lead to the so-called coolant boiling phenomenon. Reasons for car fan failure: 1. Aging of the fan itself: Many engine fans are made of plastic, and the engine compartment is constantly exposed to high temperatures. Over time, this causes the fan components to deteriorate. 2. Sensor signal interference: The fan operates based on signals from the coolant temperature sensor and refrigerant pressure sensor, which control its speed. If these sensors provide distorted signals due to external factors, it can affect the fan's operation. 3. Relay malfunction: If the fan does not turn on even when the coolant reaches the required temperature, the fan relay may be faulty. Due to aging or other reasons, the relay may remain in an open state, preventing the fan from functioning properly.

Should You Use Fog Lights or Hazard Lights in Heavy Rain?

In heavy rain, you should turn on the fog lights and may also activate the hazard lights. When visibility is reduced to only 50 to 100 meters, using fog lights alone is not safe enough. Activating both hazard lights and fog lights is necessary to ensure sufficient attention from surrounding vehicles, thereby enhancing the safety of your own and other vehicles on the road. Hazard lights should only be used in emergency situations or when temporarily stopping. Instructions for using fog lights: 1. When visibility is between 100 to 200 meters, you must turn on the fog lights, low beams, width markers, and taillights, maintaining a distance of at least 100 meters from the vehicle ahead. 2. When visibility is between 50 to 100 meters, activate the fog lights, low beams, width markers, and taillights, keeping a distance of at least 50 meters from the vehicle in front.

How often should a three-way catalytic converter cleaner be used?

A three-way catalytic converter cleaner should be used every 20,000 to 30,000 kilometers or once a year. The three-way cleaner can simultaneously clean the engine's intake system, combustion system, and exhaust system, effectively, quickly, and efficiently removing carbon deposits in the intake tract and combustion chamber, as well as chemical complexes attached to the oxygen sensor and three-way catalytic converter. The removed carbon deposits and chemical complexes will be fully oxidized and burned into gases and expelled, achieving the goal of reducing exhaust emissions and significantly lowering CO and HC levels. The three-way catalytic converter contains three precious metals: platinum (Pt), rhodium (Rh), and palladium (Pd), hence the name 'three-way.' These three precious metals facilitate the reaction of the three main harmful gases produced after engine combustion, ultimately converting them into harmless carbon dioxide, nitrogen dioxide, and water.

How often should the oil be changed for a Corolla?

The oil for a Corolla should be changed once a year or every 10,000 kilometers. Engine oil is essentially a lubricant, and its functions include: 1. Lubrication; 2. Assisting in cooling and temperature reduction; 3. Cleaning; 4. Reducing gas leakage and preventing the entry of external pollutants; 5. Preventing contact between water, air, acidic substances, harmful gases, and components; 6. Shock absorption and buffering; 7. Reducing wear caused by abrasive particles, surface fatigue, and adhesive wear. The Corolla has a body length, width, and height of 4635mm, 1780mm, and 1455mm respectively, with a wheelbase of 2700mm. It is equipped with a 1.2T turbocharged engine paired with a CVT continuously variable transmission. This engine delivers a maximum power of 85kW and a maximum torque of 185Nm.

Can a vehicle undergo annual inspection in a different location?

Can a vehicle undergo annual inspection in a different location? The procedure for entrusting an annual inspection to a different location requires the vehicle owner to first apply to the original registration location before the annual inspection can be conducted. Moreover, an application must be submitted annually to the vehicle management office of the original registration location. When applying, the vehicle must provide the driving license and the compulsory vehicle liability insurance policy. The vehicle management office will verify the vehicle and then issue a letter of authorization for the issuance of the inspection qualification mark. The vehicle owner can then apply for the inspection mark at the local vehicle management office by submitting the authorization letter for the qualification mark. Annual inspection refers to the annual or biennial safety inspection of a vehicle, which includes a comprehensive check of components such as the horn, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, and license plate installation.

What Does the W Gear in an Automatic Transmission Mean?

Automatic transmission W gear refers to the snow driving mode button, which reduces the vehicle's skidding on smooth or snowy road sections. Introduction to the various gears of an automatic transmission car: 1. P is the parking gear, used when parking; 2. R is the reverse gear, selected when reversing; 3. N is the neutral gear, selected when starting the engine; 4. D is the drive gear, selected when the car is moving forward; 5. L is the low gear, mostly used for climbing or descending slopes; 6. S is the same as gear 2, only shifting between gears 1 and 2. Method for driving an automatic transmission: After inserting the key for a few seconds, do not start the ignition immediately, as this can cause damage to the car. At this time, you need to step on the brake, then shift the car into N gear, next start the ignition, press the foot brake, finally release the handbrake, shift to D gear, and slowly release the foot brake to allow the car to move forward slowly.

What is the fuel tank capacity of the Chevrolet Cavalier?

Cavalier's fuel tank capacity is 36 liters, which is the officially announced data. The Cavalier uses 92-octane gasoline, with a fuel consumption of 4.8 to 4.9L per 100 kilometers. A full tank can run for 735 to 750km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. The fuel level is usually observed through the fuel gauge inside the car. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments, and it is advisable to refuel when there are 2 segments left to avoid running out of fuel midway. In actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safety limit, and there is still some space from the safety limit to the tank opening. This space is reserved to allow the fuel to expand when the temperature rises without overflowing the tank. If the fuel is filled to the tank opening during refueling, the actual refueling amount may exceed the calibrated tank capacity.
