What does the big F on the HOWO dashboard mean?

The appearance of a big F indicates that the water temperature is too high or there is insufficient coolant. Below are specific details about coolant: 1. Definition: The full name of coolant should be antifreeze coolant, meaning it has antifreeze functionality. Coolant prevents the liquid from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. 2. Function: Engine coolant has the characteristics of antifreeze, anti-boiling, anti-corrosion, anti-scaling, and being foam-free, unaffected by seasons or regions. 3. Quality Standards: The primary measure of coolant quality is its antifreeze performance. The freezing point of water is 0°C, while standard coolants can typically reach -40°C. High-quality coolant should achieve around -60°C, which is a key indicator of coolant quality. Another factor is the boiling point of the coolant. The boiling point of water is 100°C, whereas coolant should at least reach 108°C or higher. This means that the lower the freezing point and the higher the boiling point, the greater the temperature range, indicating better coolant quality.

What is the reason for one side of the rearview mirror not being able to fold?

The electric folding function of the exterior rearview mirror fails. Excluding mechanical and electronic control reasons, the common cause of the electric folding function failure is the battery being disconnected or out of power. Here is the relevant introduction: 1. Function: As the widest component installed on the vehicle, the rearview mirror is most susceptible to impact in the event of a collision. To minimize scratches, the rearview mirror needs to have a folding function. Rearview mirrors with a folding function can be retracted when passing through narrow sections, improving the vehicle's passability. When the driver leaves the vehicle, the rearview mirrors can also be folded, not only protecting the mirror surface but also reducing parking space and effectively avoiding scratches. In most cases, the rearview mirror folding button is located in the electric switch area on the driver's side door, but some models are exceptions, such as the gear shift base area. 2. Product features: Nowadays, rearview mirrors on mid-to-high-end vehicles are basically foldable. The folding function is divided into two types: one is manual, where the driver must reach out of the window or get out of the car to fold it, which is both inconvenient and unsafe. This type of folding rearview mirror is now rare. The other is electric folding, which is more common. Its advantage is that the driver can fold it from inside the car, and the rearview mirror will automatically open when the vehicle is started.

Where to Adjust the Carburetor for Fuel Efficiency?

When adjusting the carburetor, you can appropriately lower the fuel level in the float chamber, reduce the diameter of the main jet, and lower the main needle of the carburetor to actively decrease fuel supply, thereby achieving fuel efficiency. Below are specific methods for carburetor fuel efficiency: 1. Different methods: The main jet comes in two types—fixed and adjustable with a screw needle. For a fixed main jet, you can wrap one or two thin copper wires inside the jet to reduce fuel flow. For an adjustable type, first screw the needle all the way in, then rotate it counterclockwise about one and a half turns. The goal is to reasonably lower the mixture concentration while ensuring stable engine operation. The car should not experience jerking during acceleration or carburetor backfire. Multiple adjustments may be needed to reach an optimal level. 2. Throttle control: The throttle opening within two-thirds is the leanest and most fuel-efficient state for the mixture. When pressing the accelerator, the carburetor has a piston-type enrichment device that instantly sprays fuel, designed to enhance engine stability during acceleration. When the throttle is fully open, the carburetor opens a second fuel supply channel to enrich the mixture, allowing the engine to produce maximum power. Generally, try not to press the accelerator pedal all the way down to save fuel.

Do You Need to Turn on A/C for Car Cooling?

Car cooling requires turning on the A/C, as A/C is the cooling button. It's best to also turn on the internal circulation when cooling. Below is an introduction to car air conditioning: Heating System: Its function is to heat the air inside the car or fresh air entering from outside, achieving the purpose of warming and dehumidifying. Cooling System: Its function is to lower the temperature inside the car when the external environment temperature is high, making passengers feel cool and comfortable. Air Purification System: Its function is to filter the incoming air, continuously removing polluted gases from the car interior to keep the air inside clean.
