Should You Turn Off Bluetooth When the Car Is Turned Off?

You do not need to turn off Bluetooth when the car is turned off. This is because after the car is turned off, the entire vehicle loses power, and the car's Bluetooth device will also be in an off state, posing no safety hazards. How car Bluetooth works: Its working principle is to establish a common radio air interface for the communication environment between fixed or mobile devices, further integrating communication technology with computer technology, allowing various 3C devices to communicate or operate with each other over short distances without the need for wired or cable connections. Precautions before turning off the car: Before turning off the car, you should turn off the air conditioning and all the lights in the vehicle, as the startup of these electronic devices during ignition can place a significant load on the battery, affecting its lifespan.

Can a Car Belt with Cracks Still Be Used?

Car belts with cracks should no longer be used, as the presence of cracks indicates that the belt is about to break, which could lead to more significant issues. The Importance of Car Belts: The engine belt is the most critical belt in a car, connecting the alternator, air conditioning compressor, power steering pump, idler pulley, tensioner pulley, and crankshaft pulley. Once small cracks appear on the belt, it needs to be replaced. If the belt breaks, it can cause the alternator to stop generating electricity, the power steering pump to fail, and make steering difficult, which is a very dangerous situation. Inspection and Replacement of Car Belts: During every maintenance service, the belt tension and wear should be checked. Even if everything appears normal, the belt should generally be proactively replaced at around 80,000 kilometers.

What Causes High Temperature in Car Air Conditioning Radiator?

Car air conditioning radiator temperature is high due to malfunctioning electric fans or blockage by foreign objects causing poor heat dissipation. Below are the causes and solutions for this issue: Malfunctioning electric fan: The car's electric fan is controlled by a thermostat. When the water temperature rises to the upper limit, the thermostat activates the power supply, and the fan starts working. If the electric fan is not functioning properly, the radiator will not cool down in time. It is necessary to check the performance of the electric fan and its control system. Radiator surface covered by foreign objects: If the radiator surface is covered by foreign objects or clogged with dirt, heat cannot dissipate into the air. Cleaning the surface coverings promptly will solve the issue.
