How Often Should a Car Cooling Fan Be Replaced?

Car cooling fans do not require regular replacement. When the coolant in the radiator reaches a certain temperature, the thermal switch controls the activation of the radiator fan. When the coolant temperature rises further, the thermal switch increases the fan speed. Once the coolant temperature drops to a certain level, the radiator fan automatically turns off. Below is an introduction to car maintenance: 1. Exterior Inspection: Before driving, check the doors, hood, trunk, and glass condition. Inspect the car body for damage, tilting, oil or coolant leaks, etc. 2. Engine and Various Fluids: Check the fastening of engine components and inspect for oil or coolant leaks at engine joints. Adjust belt tension and inspect the fastening of hoses and wiring. Top up engine oil, coolant, and battery electrolyte as needed. 3. Tires: Check tire wear and clean the trunk. Replace tires when they approach the wear indicators. Inspect for bulges, abnormal wear, aging cracks, or damage. 4. Cleaning and Lubrication: Clean grease from the engine compartment hood, door hinges, and trunk hinges, then lubricate them. Antifreeze typically lasts 2 years and should be replaced during maintenance, with a thorough cooling system flush. Due to the hygroscopic nature of the brake system, brake fluid should be replaced every two years.

What does car lottery mean?

Car lottery is a measure of vehicle purchase restriction, which limits the number of car registrations. The method and winning rate of the car lottery are as follows: Method of car lottery: The method of lottery car purchase is to first register for an appointment and queue, and then participate in the lottery uniformly. The computer randomly generates 10 numbers, and the lottery participant selects one number from them. The lottery is actually similar to drawing lots, and only those who win are eligible to buy a car. Winning rate of car lottery: The tiered winning rate is set based on the cumulative number of times an individual participates in the lottery. If you participate in the lottery 24 times (inclusive) or less without winning, the winning rate is the current benchmark winning rate; if you participate in the lottery 25 to 36 times without winning, the winning rate automatically increases to twice the benchmark winning rate; if you participate in the lottery 37 to 48 times without winning, the winning rate automatically increases to three times the benchmark winning rate, and so on.

What Are the Reasons Why a Car Cannot Charge?

It is caused by damage to the storage battery or generator, which can be resolved by replacing the storage battery or repairing the engine. Below are the specific reasons: Battery Damage: The automotive battery, also known as the storage battery, is one of the essential components in a car. Its primary function is to provide energy to the starter when the car engine starts, and it also serves as the power source for onboard electrical devices. If the battery is damaged, the vehicle cannot store electricity. Even after prolonged charging, the battery will remain in a discharged state, and the car will fail to start after turning off the engine. Timely replacement of the battery is necessary. Generator Damage: The car generator supplies power to all electrical devices except the starter while the engine is running normally and simultaneously charges the battery. The generator is the main power source of the car. If the generator malfunctions, the battery cannot be charged. This issue can be resolved by repairing or replacing the generator.

Why doesn't the car door open when pressing the unlock button?

If the car door doesn't open when pressing the unlock button, it may be due to a damaged door lock actuator. Here's an introduction to door lock actuators: 1. Definition: A car door lock actuator is a specialized term, essentially referring to the car door lock controller. 2. Device: It serves as the control device that provides locking/unlocking pulse current to the door lock actuator. 3. Function: Regardless of the type, all door lock actuators control the left-right movement of connecting rods by changing the direction of electrical current, thereby achieving door locking and unlocking. The worm gear fixed on the motor output shaft meshes with a gear, while the gear's inner chamber meshes with a swing arm. Its working principle is: the vehicle's current source powers the motor, whose rotation is converted into the swing arm's oscillation, thus completing either an opening or closing cycle.
