After adding water to automotive antifreeze, the performance of the antifreeze will decrease. The full name of antifreeze is antifreeze coolant, meaning a coolant with antifreeze properties. Antifreeze prevents the coolant from freezing and expanding in cold winter conditions, which could otherwise crack the radiator or damage the engine block or cylinder head. Functions of Antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent properties such as preventing freezing in winter, boiling in summer, and providing year-round protection against scale and corrosion. Composition of Antifreeze: The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances. Types of Antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can Different Antifreeze Brands Be Mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering the additives ineffective.

What is the ground clearance of the Haval H2?

Haval H2's ground clearance is 150mm, which meets the standard for a compact SUV.

How to Turn on the Fog Lights of an Audi?

Audi's headlights and fog lights are turned on in the same way across all models. Taking the domestic Audi A4L as an example, the switch is located below the air vent on the driver's side. The middle knob controls the width lights and low beams, while the two buttons on the left, arranged vertically, are for the front and rear fog lights—simply press them to activate. The right side features controls for the interior lights and instrument panel brightness adjustment. The purpose of fog lights is to make the vehicle visible to others in conditions of reduced visibility, such as fog or heavy rain. Therefore, fog light sources need strong penetration. Most vehicles use halogen fog lights, while more advanced models may feature LED fog lights. Fog lights must be installed below the bumper, as close to the ground as possible, to ensure their effectiveness. If positioned too high, the light cannot penetrate the fog or rain to illuminate the road (since fog is usually thinner below 1 meter), which could lead to hazardous situations. Typically, fog light switches have three positions: the 0 position is off, the first position controls the front fog lights, and the second position controls the rear fog lights. When set to the first position, only the front fog lights are on; at the second position, both front and rear fog lights operate. Therefore, when turning on the fog lights, it's advisable to know which position the switch is in, ensuring convenience for yourself and safety for others on the road.

Has the Oil Emulsification Issue in Toyota Hybrids Been Resolved?

Toyota hybrid oil emulsification issue has not been resolved yet. Hazards of oil emulsification: Oil and water are incompatible, but under certain temperatures and specific conditions, they can mix and cause emulsification. Emulsified oil turns white. Since engine oil lubricates engine components, its performance significantly declines after emulsification, leading to severe engine wear and reduced engine lifespan. Therefore, oil emulsification is not a minor issue. Normal oil emulsification phenomenon: Sometimes, when the engine is turned off and cools down, air enters the valve chamber where the camshaft is located. Condensation of water vapor in the air can cause slight emulsification on the oil cap. The accumulation of emulsion on the oil filler cap is entirely different from the oil emulsification issue. This is a normal occurrence and does not fall under the category of oil emulsification problems.

Does the Haval H2 have a four-wheel drive version?

Haval H2 does not have a four-wheel drive version; all models adopt a front-wheel drive system. The structure of the front-wheel drive system is relatively simple, resulting in lower manufacturing costs and fewer malfunctions. Some vehicle models use a rear-wheel drive system, which offers greater playability and a certain level of driving enjoyment. The Haval H2 is positioned as a compact SUV, with dimensions of 4330mm in length, 1815mm in width, and 1700mm in height, and a wheelbase of 2560mm. The Haval H2 continues the Haval family's signature design with hexagonal and large U-shaped front grille options, complemented by standard LED daytime running lights with a diamond-inlay effect, creating a highly recognizable front face.
