What is the reason for the constant rotation of the Volkswagen Tiguan's fan?

Volkswagen Tiguan's fan keeps running for cooling purposes. The following are the reasons why the Volkswagen Tiguan's fan keeps running: Cooling: The fan in the car serves to dissipate heat, so when the coolant temperature is too high after parking, the vehicle's computer automatically calculates the fan's speed and duration. The higher the temperature, the longer the fan runs, thereby protecting the engine. Therefore, there is no need to worry; this is a normal phenomenon. If the engine coolant temperature at the moment of parking is higher than the acceptable soaking temperature for the engine, the vehicle's computer will automatically calculate the fan's operating speed and duration, thus controlling the fan's operation automatically. The higher the motor's temperature, the longer the fan will run after stopping.

What Causes the Squeaking Sound When Braking at Car Startup?

The reasons for the squeaking sound when braking at car startup are: 1. Use of low-quality or overly hard brake pads; 2. Presence of sand or foreign objects between the brake pads and brake discs. Due to the unique design of disc brakes, some sand and foreign objects may inevitably get between the brake pads and discs, causing noise during braking; 3. Severe wear of the brake discs; 4. Brake pad warning. If the wear level of the brake pads reaches the warning line, it will emit a squeaking alarm sound. Car brake pads, also known as car brake linings, generally consist of steel plates, adhesive heat insulation layers, and friction blocks. They refer to the friction materials fixed on the brake drums or discs that rotate with the wheels. The friction linings and friction blocks within them bear external pressure to generate friction, thereby achieving the purpose of vehicle deceleration.

What Are the Causes of Radiator Leaks?

Possible causes of car radiator leaks include: hose rupture, oil emulsification, loose radiator cap, leaking rubber hose connections, broken cooling tubes, or radiator cracks. The car radiator, also known as the heat exchanger, is a key component in the vehicle's cooling system. Its function is to dissipate heat. The coolant absorbs heat in the water jacket, flows to the radiator to release the heat, then returns to the water jacket in a continuous cycle, achieving temperature regulation. The radiator is a crucial part of water-cooled engines, serving as a major component in the engine's cooling circuit. It absorbs heat from the engine block to prevent overheating. Due to water's high specific heat capacity, its temperature doesn't rise significantly after absorbing heat from the engine block. Thus, the engine's heat is transferred through the liquid cooling circuit using water as the heat carrier, then dissipated via large cooling fins through convection to maintain the engine's optimal operating temperature.

What to Do When the ETC Tag Shows Invalid?

If the ETC tag shows invalid, you need to go to the ETC installation point designated by the highway management office to reactivate it and reinstall it on the vehicle's windshield before it can be used normally. The OBU device has a touch switch button. Once the OBU device falls off the front windshield, the button will pop up and lock, showing an invalid tag prompt. Alternatively, accidentally pressing the touch switch button can also directly cause the ETC tag to become invalid. The ETC (Electronic Toll Collection) system is an automatic toll collection system for highways or bridges. It uses dedicated short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, combined with computer networking technology and bank backend settlement processing, to achieve the purpose of vehicles passing through highway or bridge toll stations without stopping to pay toll fees.

What functions should be turned off in vehicles during heavy rain?

During heavy rain, functions such as auto start-stop and auto hold should be turned off. Here are some driving tips for heavy rain conditions: 1. Proper use of lights: Whether it's day or night, always turn on the low beam and side marker lights when driving in rainy or foggy weather. If the rain is too heavy or visibility is poor due to thick fog, turn on the fog lights. Hazard lights should only be used when parking or during emergency braking to alert vehicles behind. They should not be turned on randomly during normal driving, as this can make it difficult for drivers behind with poor visibility to discern lane-changing intentions or spot vehicles stopped on the road due to various reasons in bad weather. 2. Low speed and high RPM when passing through waterlogged areas: When driving through waterlogged areas, use a low gear and maintain a slow speed. Keep the throttle steady and avoid stopping, shifting gears, or making sharp turns midway. Even if you're in neutral, keep revving the engine to maintain exhaust pressure higher than the water pressure, preventing water from flowing back into the exhaust pipe and damaging the exhaust system. If the water level reaches the center of the wheel or covers the exhaust pipe, it's best not to proceed to avoid stalling the engine while passing through.

What are the new regulations for vehicle annual inspections?

New regulations for vehicle annual inspections: Starting from November 20, 2020, non-operational small and mini buses (excluding vans) with 7-9 seats that are within 6 years of age are included in the exemption range; for those over 6 years but under 10 years of age, the inspection cycle is relaxed from once a year to once every two years. This means private cars only need to undergo two on-site inspections within 10 years, specifically in the 6th and 8th years. Contents of the annual inspection: Check whether the engine, chassis, body, and their auxiliary equipment are clean, complete, and effective, whether the paint is uniform and aesthetically pleasing, whether the main assemblies have been replaced, and whether they match the initial inspection records; Test whether the vehicle's braking performance, steering control, lights, exhaust, and other safety features comply with the "Technical Conditions for Safe Operation of Motor Vehicles"; Check whether the vehicle has been modified, remodeled, or altered, whether the driving license, license plate, and all registered vehicle records match the actual condition of the vehicle, whether there are any changes, and whether approval and modification procedures have been completed; Check whether the license plate, driving license, and the enlarged license plate characters printed on the vehicle are damaged, altered, or illegible, and whether they need to be replaced; For large vehicles, check whether the unit name or the name of the street, township, or town where the vehicle is located, along with the maximum seating capacity in the driver's cabin, is printed in Chinese imitation Song font on both sides of the door as required; For trucks, check whether the rear fender (including the trailer's rear fender) has the vehicle number enlarged 2-3 times on the outside as required, and whether the sides of the door for individual or joint-venture vehicles are printed with the word "individual"; the characters must be clear, and unit codes or other patterns are not allowed (special cases require approval from the vehicle management office).
