What is the engine model of the BAIC Huansu S3?

BJ415C is the engine model used in the BAIC Huansu S3, with a maximum horsepower of 113 hp, a maximum power of 83 KW, a maximum power speed of 6000 rpm, and a peak torque of 150 N.m. The engine of the BAIC Huansu S3 is produced by BAIC Yinxiang Automobile Co., Ltd. For the daily maintenance of the BAIC Huansu S3 engine, the following methods can be used: Use lubricating oil of appropriate quality grade. For gasoline engines, SD--SF grade gasoline engine oil should be selected based on the additional devices of the intake and exhaust systems and usage conditions; for diesel engines, CB--CD grade diesel engine oil should be selected according to mechanical load, with the selection standard not lower than the requirements specified by the manufacturer. Regularly change the oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, performance deteriorates, which can cause various problems for the engine. To avoid faults, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When oil passes through the fine holes of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter is blocked and the oil cannot pass through the filter element, the filter element may burst or the safety valve may open, allowing oil to bypass through the bypass valve and still carry dirt back to the lubrication area, 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, mixing with metal powder from component wear to form sludge. When the amount is small, it remains suspended in the oil; when large, it precipitates from the oil, blocking filters and oil holes, making engine lubrication difficult and causing wear. Regularly use radiator cleaner to clean the radiator. Removing rust and scale not only ensures the normal operation of the engine but also extends the overall lifespan of the radiator and engine.

What to Do When Fog Lights Get Water Inside?

Fog lights generally refer to the automotive fog lights installed at the front and rear of the vehicle. If water enters the fog lights, it can be addressed based on the following two levels of water ingress: 1. Minor water ingress: After turning on the lights for a period of time, the heat generated can help the internal moisture evaporate and escape through the vent tube. When using hot air, ensure even heating and avoid concentrating heat in one spot to prevent damage to the headlight assembly. 2. Severe water ingress: It is necessary to promptly remove the lamp cover, disassemble it, and dry out the water. Additionally, inspect the headlight for any cracks or leaks, and replace any damaged components if found.

Where to Check the Vehicle Production Date?

There are three ways to check the vehicle production date: 1. The production date is located below the B-pillar on the passenger side, visible upon opening the door, but this plate only specifies the year and month. 2. The certificate of conformity that comes with the new vehicle, located in the upper right corner of the certificate, where the production date is marked and can be specified to the exact day, month, and year. 3. The vehicle's chassis number, like an ID card, contains the production date. The chassis number, also known as the Vehicle Identification Number (VIN), is a set of seventeen letters and numbers used to represent vehicle information. The tenth letter or number in the chassis number indicates the vehicle's production date, with the year code repeating every 30 years.

Is it mandatory to service the car at the dealership where it was purchased?

Car maintenance does not necessarily have to be done at the dealership where the car was purchased; any authorized dealership nationwide that matches the car's brand and model can perform the service. Typically, car warranty policies last for 2 years or 60,000 kilometers (whichever comes first), with some models having slightly longer warranty periods, but generally not exceeding 5 years or 100,000 kilometers. Here are some details about car maintenance: 1. Car maintenance (Car-maintenance), also known as car servicing, refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. 2. Car maintenance mainly includes servicing the engine system, transmission system, air conditioning system, etc., aiming to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent malfunctions, and extend the usage cycle.

How to Perform Pressure Testing for Leak Detection in Car Air Conditioning?

Car air conditioning pressure testing for leak detection is performed as follows: 1. Properly connect the air conditioning pressure gauge to the high and low pressure pipelines of the air conditioning system (red for high pressure, blue for low pressure), then connect the air pump to pressurize the system. 2. After pressurization, close the high and low pressure valves on the pressure gauge, let it sit for 10-15 minutes, observe the pressure gauge needle to check for any leaks in the air conditioning system and locate the leak points. Notes for pressure testing for leak detection: 1. The pressure for car air conditioning testing is generally around 20-30 Bar, which is higher than the working pressure of the car air conditioning system. 2. Ensure that leak detection is completed before proceeding with vacuuming the air conditioning system and adding refrigerant. After completing the pressure testing for leak detection and vacuuming, you can directly add the refrigerant.
