The vent hole of the headlight is located at the lower left position of the steering wheel. Function of the vent tube: Whether it's a regular halogen headlight, xenon headlight, or LED headlight assembly, there is a vent rubber tube on the rear cover. When the headlight is turned on and during use, a large amount of heat is generated. The function of the vent tube is to expel this heat as much as possible outside the headlight to maintain the normal operating temperature of the headlight and ensure its stable performance. Principle of fog expulsion: Moisture in the air can enter the headlight through the vent tube and condense on the lens. As moisture accumulates, water droplets will flow down the lens. This phenomenon mostly occurs due to significant temperature differences and is most common in winter and rainy seasons. After the headlight has been on for a while, the fog will be expelled through the vent tube along with the hot air, which generally does not damage the headlight or electrical circuits.

Does the Baojun 730 Have Anti-Collision Beams?

Baojun 730 has anti-collision beams. The Baojun 730 is equipped with front and rear anti-collision steel beams, with a thickness of 2-3 mm. In addition to the front and rear anti-collision beams, the car also has anti-collision beams inside all four doors. Relevant information is as follows: 1. The anti-collision beam is a U-shaped channel formed by stamping cold-rolled steel plates and is connected to the frame longitudinal beams. 2. The anti-collision beam is an important safety device that absorbs and mitigates external impacts, protecting the front and rear parts of the vehicle body. 3. Sometimes, the anti-collision beam only serves a decorative role, while the real safety protection comes from the anti-collision steel beams inside the bumper.

What type of engine oil is best for the Changan CS35?

For the Changan CS35, it is recommended to use SL-grade 5W-30 viscosity engine oil. The required oil volume is 3.4L. After filling, the oil level on the dipstick should be between the MIN and MAX marks, neither below MIN nor above MAX. Note that engine oil should only be added when the engine is cool. Relevant details are as follows: 1. The '5W' indicates low-temperature viscosity; the smaller this number, the better the oil's fluidity. The '30' represents high-temperature viscosity; the larger this number, the higher the oil's viscosity and the better its sealing properties. 2. Higher oil viscosity is not always better. If the oil's viscosity is too high, it can also affect the engine. Higher viscosity means relatively poorer fluidity, which may prevent the oil from promptly covering all engine components, thus failing to fully utilize the oil's functions.
