Yes, you need to change the transmission fluid. Generally, it should be replaced every two years or 40,000 kilometers. Transmission fluid deteriorates and evaporates over time when working under high-speed and high-temperature conditions, so regular replacement is necessary. Failure to change it can accelerate the wear of mechanical components. Transmission fluid helps keep the gear system clean, lubricates the transmission components, and extends their service life. It is a lubricant specifically designed to maintain the cleanliness of the gear system and enhance the longevity of the transmission. It also provides effective lubrication in low-temperature conditions, reducing fluid loss under harsh operating conditions. Depending on the transmission type, transmission fluid is categorized into automatic transmission fluid (ATF) and manual transmission fluid.

Does the Nissan Qashqai have front and rear anti-collision beams?

Nissan Qashqai is equipped with front and rear anti-collision beams, both of which come with pedestrian protection foam. Here is the information about the front and rear anti-collision features: 1. Function of anti-collision beams: The anti-collision beam is a device designed to absorb collision energy when the vehicle is impacted. It consists of a main beam, an energy-absorbing box, and mounting plates that connect to the vehicle. Both the main beam and the energy-absorbing box can effectively absorb collision energy during low-speed impacts, minimizing the damage to the vehicle's longitudinal beams and thereby protecting the vehicle. 2. Front anti-collision beam: The front anti-collision beam is made of a double-layer arched rolled steel plate with a thickness of 1.22 mm. It uses a double-layer rolling process and covers 65.4% of the area. 3. Rear anti-collision beam The rear anti-collision beam is of a lower grade than the front one, but its structure is very similar to the front anti-collision beam. It comes with thick pedestrian protection foam, and the thickness of the anti-collision beam is only 1.22 mm. The overall length is slightly longer, and the rear coverage area reaches 70.06%.

What engine does the Civic use?

The Civic is equipped with Honda's Earth Dreams series turbocharged direct injection engine, utilizing Honda's proprietary technology and classified as a domestically produced engine. The Civic's 1.5T engine model is L15B8, delivering a maximum power of 130kW and a maximum torque of 220Nm. The 1.0T engine model is P10A1, with a maximum power of 92kW and a maximum torque of 173Nm. For daily maintenance of the Civic's engine, the following methods can be employed: Use lubricating oil of appropriate quality grade. For gasoline engines, select SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions. For diesel engines, choose CB--CD grade diesel engine oil according to mechanical load, ensuring the standard meets or exceeds the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will degrade over time. After a certain mileage, its performance deteriorates, leading to various engine issues. To prevent malfunctions, change the oil periodically based on usage conditions and maintain an appropriate oil level. As oil passes through the fine pores of the filter, solid particles and viscous substances accumulate in the filter. If the filter becomes clogged and oil cannot pass through, it may rupture the filter element or open the safety valve, allowing oil to bypass through the relief valve and carry contaminants back to the lubrication points, accelerating engine wear and increasing internal contamination. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls. These mix with metal particles from component wear to form sludge. In small amounts, the sludge remains suspended in the oil, but in larger quantities, it precipitates, clogging filters and oil passages, making engine lubrication difficult and causing wear. Periodically use a radiator cleaner to flush the radiator. Removing rust and scale deposits not only ensures the engine operates smoothly but also extends the overall lifespan of both the radiator and the engine.

Is Car Window Film Applied on the Inside or Outside?

Car window film is applied on the inside. Here is relevant information about car window film: 1. Functions: Heat insulation and sun protection, UV blocking, safety and explosion-proof, creating private space, reducing air conditioning load, saving fuel, enhancing aesthetics, and preventing glare. 2. Working principle: Through vacuum plating or magnetron sputtering technology, metals such as aluminum, gold, copper, and silver are made into multi-layered, tightly packed high-heat-insulation metal film layers. The higher the metal's conductivity coefficient, the shallower the penetration depth and the higher the reflectivity. These metal layers selectively reflect various heat energy sources in sunlight, including infrared, ultraviolet, and visible light heat energy. Combined with the film's color absorbing solar heat radiation and then releasing it outward again, part of the heat is carried away by outdoor air flow. Thus, it effectively achieves the function of heat insulation.
