Motorcycle high water temperature with fan not working reasons are as follows: 1. The engine's high water temperature is mainly caused by the electric fan not starting. After troubleshooting the electric fan issue, the water temperature will return to normal; 2. If the electric fan is not working, first check if the connector has poor contact, inspect the power supply and grounding of the electric fan, check if the fan is stuck, and verify if the fan motor is burnt out. Motorcycle engine cooling systems generally come in three forms: natural air cooling, forced air cooling, and water cooling. Below are their working principles: 1. Natural air cooling: Utilizes the natural wind encountered during the motorcycle's movement as the cooling medium to carry away heat from the cylinder and cylinder head fins, ensuring the motorcycle engine's heated components operate within the appropriate temperature range. 2. Forced air cooling: Uses a fan to increase the velocity of cooling air flowing through the fins, achieving efficient cooling. 3. Water cooling: Uses water as a heat-absorbing medium to cool high-temperature parts and then transfers the heat to the external air, maintaining the engine at the most suitable operating temperature.

What to Do When Lexus Has No Sound When Playing Music?

1. Navigation: Check whether the power supply of the vehicle's DVD navigation or the display screen in the center of the control console is functioning properly. You can first turn off the power and then try restarting it. 2. Steering Wheel: Determine if the car is equipped with a multifunction steering wheel. Generally, there is a mute function on the multifunction steering wheel; check if this button is turned off. 3. Sound: Check if the sound option on the display screen is turned on. Alternatively, it might be due to a temporary interruption of signal input caused by answering a Bluetooth call. In this case, simply wait for the Bluetooth call to end, and the signal will automatically restore, allowing sound to return to normal. 4. USB Drive: If using a USB external playback device, check if the USB drive is loose and not receiving a signal input.

What type of fuel should the Tiguan use?

The Tiguan is recommended to use fuel with an octane rating of 95 or higher. Below are the relevant details: 1. Octane Rating: Different octane ratings of gasoline are actually configured based on the requirements of engines with varying compression ratios. In principle, engines with a compression ratio greater than 9:1 must use gasoline with an octane rating of 90 or above; those with a ratio greater than 9.5:1 are best suited for 92 or above; and those exceeding 10:1 perform optimally with 95 or above. 2. Engine Considerations: Whether to use 92 or 95 octane gasoline depends on the engine's operating temperature and pressure. Generally, naturally aspirated engine vehicles require 92 octane gasoline, while turbocharged engine vehicles typically need 95 octane gasoline.
