Why is the car air conditioning not heating up?

Reasons why the car air conditioning is not heating up: 1. The water pump impeller is damaged or slipping, resulting in insufficient flow through the small heater radiator, preventing heat from rising; 2. There is airlock in the engine cooling system, which causes poor circulation in the cooling system, leading to high water temperature and ineffective heating. The car air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle, providing a comfortable environment for passengers, reducing driver fatigue, and improving driving safety. Air conditioning has become one of the indicators to measure whether a car is fully equipped. Modern air conditioning systems consist of a refrigeration system, heating system, ventilation and air purification devices, and a control system.

Why Buy a Civic with a Manual Transmission?

Manual transmissions have all the advantages that automatic transmissions lack. Here is a brief introduction to manual transmissions: 1. Advantages: Manual transmissions are characterized by their simple structure, reliable performance, low manufacturing and maintenance costs, and high transmission efficiency, which theoretically makes them more fuel-efficient. Additionally, due to pure mechanical control, gear shifts are quicker and more responsive to the driver's intentions, offering a more engaging driving experience. 2. Principle: In a manual transmission car, the power input shaft is connected to the clutch, and the power transmitted from the clutch is directly delivered to the gear set via the input shaft, enabling gear shifting.

Is a Car Manufactured 9 Months Ago Considered New?

No, a car manufactured 9 months ago can be considered as inventory stock. Below is relevant information about inventory cars: 1. Definition: There is no clear legal definition for inventory cars, but the automotive sales industry does recognize the term 'inventory cars', which generally refers to vehicles that have remained unsold for over a year. 2. How to Identify: Actually, there's no need to identify whether a car is an inventory vehicle or not. Firstly, the manufacturing date is clearly stated on the vehicle's nameplate. Secondly, dealers won't conceal the identity of an inventory car because it's impossible to hide. What needs to be determined is whether the car has been properly maintained and serviced during its inventory period.

What causes abnormal noises when the car is running?

Vehicle driving abnormal noise causes are as follows: 1. Exhaust pipe deformation: Generally, the exhaust pipe of front-engine models extends from the bottom of the car to the rear. When driving on rough roads or bumping the chassis, it is easy to cause the exhaust pipe to dent and deform. The deformed exhaust pipe increases exhaust resistance, resulting in a buzzing noise and resonance sensation. 2. Engine abnormality: Mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can still be predicted, while engine abnormal noises may lead to accident damage. Therefore, when the engine makes abnormal noises, it should be repaired in time to prevent the fault from expanding.

What is TCS?

TCS stands for Traction Control System, which functions to control direction and improve traction when a vehicle skids, preventing loss of control. The Traction Control System determines whether the drive wheels are slipping by comparing the rotation speed of the drive wheels with that of the driven wheels. When the former exceeds the latter, it suppresses the rotation speed of the drive wheels as a form of anti-skid control. Vehicle traction control can be achieved by reducing throttle opening to decrease engine power or through brake control and wheel slip. Vehicles equipped with ASR (Acceleration Slip Regulation) utilize both methods, combining ABS (Anti-lock Braking System) and ASR.
