What is the low coolant level warning light icon?

When the coolant level is low, a thermometer icon will illuminate on the vehicle's dashboard. The functions of coolant are as follows: 1. Cooling function: Cooling is the basic function of coolant. When the engine is running, it generates a large amount of heat, with 60% of this heat being dissipated to the surrounding space through the cooling system. Water and methanol-based coolants have low boiling points and are prone to boiling. If the vehicle operates under conditions where the coolant is boiling, even for a short period, it can cause engine damage or even complete failure. 2. Anti-corrosion function: The cooling system consists of components such as the radiator, water pump, cylinder block, cylinder head, and water distribution pipes made from various metals including steel, cast iron, brass, copper, aluminum, and solder. Due to the different electrode potentials of these metals, electrochemical corrosion can easily occur in the presence of electrolytes. Additionally, acidic byproducts formed from the decomposition of glycol-based substances in the coolant, as well as acidic exhaust gases from fuel combustion that may penetrate the cooling system, can accelerate corrosion within the cooling system.

What is the safety standard for brake disc thickness?

The safety standards for brake disc thickness are as follows: Mechanical performance requirements: Tensile strength >=206MPa, bending strength >=1000MPa, deflection >=5.1mm, hardness should be between 187~241HBS. Additional information: 1. Brake disc classification: (1) Structurally, there are solid brake discs and ventilated discs. Solid brake discs are simply metal discs used for braking without any special construction. Ventilated discs come in two forms: slotted discs and drilled discs. Both treatments aim to improve the cooling performance of the brake disc, reduce thermal fade, and provide better braking capability. (2) By material, they are divided into carbon fiber ceramic brake discs and metal brake discs. 2. Brake disc selection: First, check whether the replacement brake disc is a genuine part, the integrity of the product packaging, whether the anti-counterfeiting marks and packaging labels match those on the brake disc, and whether the product model matches the content of the certificate. Brake discs produced by regular manufacturers have clearer packaging prints, including license numbers and execution standards, while the packaging box contains a certificate of conformity, production batch number, production date, etc.

Can fog lights be installed on a car?

Fog lights can be installed on a car, and the installation method is as follows: 1. Locate the reserved position for the fog lights and secure them in place; 2. Refer to the circuit diagram to connect the fog light wiring; 3. Add a fuse to complete the installation. Front fog lights are used to illuminate the road and provide safety warnings during rainy or foggy weather, thereby improving visibility for the driver and other traffic participants. Important precautions for using fog lights include: 1. Fog lights must be turned on and speed must be reduced when visibility drops below 100 meters; 2. If visibility is below 30 meters, turn on the fog lights, pull over to the side of the road, and activate the hazard warning lights; 3. In conditions of rain, fog, snow, or dust, turn on the fog lights and reduce speed.
