Why does the Volkswagen Tiguan's fan keep running after the engine is turned off?

It is normal for the engine fan to continue running after the car is parked and the engine is turned off. The automatic activation of the engine fan is due to the engine overheating after prolonged operation. The computer system detects this and initiates the fan to cool down the engine, preventing rapid temperature drop after stopping, which could lead to "cylinder seizure" and engine failure. Below is an introduction to the electric fan: 1. Composition: The electric fan is designed to prevent the engine coolant temperature from becoming too high. It consists of sensors, the electric fan, chips, and other components. 2. Function: When the coolant temperature generally exceeds 90 degrees, the sensor activates, and the electric fan turns on to lower the temperature. In winter, when temperatures are lower and the coolant temperature is also lower, the electric fan usually does not operate, protecting the engine from working in excessively cold or hot conditions.

I've been running an auto repair shop for many years and often encounter issues like this with the Volkswagen Tiguan. It's actually quite common for the fan to keep running after the engine is turned off. This is usually caused by the engine temperature being too high, requiring continued cooling, especially in turbocharged cars like the Tiguan. After parking, the turbo remains very hot, and the electronic control unit will force the fan to keep running to cool it down. Other reasons include a faulty temperature sensor, which might misread the temperature and prevent the fan from stopping; or a stuck fan relay that keeps the fan powered; or loose or short-circuited wiring. Normally, the fan should stop within 5 to 10 minutes. If it runs for more than 15 minutes, you should check if the coolant is sufficient or if the radiator is clogged. I recommend feeling the hood to see if it's unusually hot. If it is, take it to a professional shop immediately to avoid battery drain or component damage.

Where Do Flood-Damaged Cars End Up?

Flood-damaged cars may end up as collateral vehicles, enter the used car market, or be recycled. Here's a partial overview of the destinations for flood-damaged vehicles: 1. Becoming collateral vehicles: Some flood-damaged cars are purchased by individuals to use as collateral for loans. Particularly luxury vehicles can still secure substantial loan amounts. 2. Entering the used car market: Experienced used car dealers acquire these vehicles at very low prices, then modify and refurbish them. After modification, these cars appear nearly new and are sold at inflated prices. 3. Being reclaimed: Some flood-damaged vehicles that haven't been registered are ultimately repurchased by manufacturers. These cars may be sold to internal employees, specifically staff at car dealerships who are very familiar with used car dealers, ultimately returning these vehicles to the market.

Does prolonged exposure to rain affect a car?

Leaving a car exposed to rain for extended periods can lead to bacterial growth inside the vehicle, potentially affecting occupants' health. Below are some hazards associated with prolonged water exposure in cars: 1. Bacterial growth: After heavy rain, it's essential to inspect the car interior. Appropriate disinfection should be performed post-rain to maintain a clean and comfortable cabin environment. More importantly, this ensures a safer and healthier experience for drivers and passengers by preventing bacterial contamination. 2. Check the chassis to prevent wheel well loosening and perforation: After rain exposure, mud accumulation in the wheel wells and chassis areas can trap moisture, leading to rust formation. In severe cases, this may cause loosening or perforation in the wheel wells, potentially resulting in safety hazards.

How Many Liters of Gasoline Can a Car Hold?

Different car models have varying fuel tank sizes, resulting in different gasoline capacities. Here are the specific details about car fuel tank capacity: 1. Meaning of the fuel gauge: The fuel gauge on the dashboard has 5-6 segments, each representing the remaining fuel capacity in the tank. Generally, you need to refuel when the fuel gauge shows two segments left. 2. Fuel tank capacity measurement unit: The international standard uses liters (L) as the unit for measuring car fuel tank capacity, with different countries having their own standards. 3. Relationship between engine displacement and fuel tank volume: Typically, small cars have a fuel tank capacity of 35-45 liters, while mid-sized cars have a capacity of around 55-75 liters. A full tank usually allows for a driving range of approximately 500 kilometers. The fuel tank volume varies based on the engine displacement and the vehicle's own weight.

What are the reasons for Cadillac air conditioning not cooling?

Cadillac car air conditioning not cooling reasons and solutions are as follows: 1. Lack of refrigerant: Insufficient refrigerant in the air conditioning system pipelines leads to reduced pressure and decreased heat dissipation, resulting in a feeling that the air conditioner only blows air without cooling. Generally, there may be slight leaks in the air conditioning pipelines or condenser, which is a normal phenomenon. If the refrigerant is insufficient or too low, it must be replenished. However, note that if adding from the low-pressure side, do not invert the refrigerant bottle; if adding from the high-pressure side, do not start the engine. After replenishment, check for severe leaks. 2. Condenser blockage: If the air conditioning system has not been maintained for a long time, the air filter and condenser may become too dirty or blocked, leading to poor cooling performance. If you really don’t have the habit of regular air conditioning system maintenance, then perform a thorough cleaning of the system. Moreover, replacing the air filter is very simple and requires almost no learning cost, so car owners can replace it regularly.

Is the Wuling Mini Truck a Restricted Truck?

It depends on the specific requirements of the area. The Wuling mini truck is classified as a micro truck, which is a type of light truck. If certain areas of the city explicitly prohibit trucks from entering, then the Wuling mini truck is also not allowed to enter. Typically, there will be a prohibition sign featuring a red circle with a red 45-degree diagonal line crossing a truck symbol. Below is an introduction to truck prohibition signs: Prohibition signs are primarily used to forbid or restrict the traffic behavior of vehicles and pedestrians, with the graphics mainly being a red circle. The main reason for truck restrictions is that trucks are large in size and relatively slow in speed, while urban traffic is heavy and most roads are quite narrow. Therefore, restrictions are imposed to some extent to prevent traffic congestion. Generally, truck restrictions are implemented in areas with heavy traffic, and most restrictions are lifted after 9 PM or on weekends, allowing trucks to pass through.

What causes a gasoline-to-CNG converted vehicle to stall when switching to gas?

The main reason is improper gas flow adjustment during the gasoline-to-CNG conversion, which requires readjustment. Below are specific maintenance methods for CNG-converted vehicles: 1. System maintenance: Regular system maintenance is essential for CNG-converted vehicles. Due to the special properties of the fuel used, a comprehensive leak test should be conducted on the gas tank every two weeks. 2. Driving habits: Proper driving habits are crucial for maintaining optimal performance in CNG-converted vehicles. During daily operation, ensure the vehicle is equipped with fire extinguishing equipment. If the vehicle will be parked for an extended period, the CNG should be depleted. Never service the fuel supply system in enclosed garages or workshops. 3. Routine maintenance components: CNG-converted vehicles may experience stalling during operation, which can be caused by improper cleaning of the air filter, incorrect fuel injection delay adjustment of the fuel injection simulator, or improper adjustment of the pressure reducer.
