Can I Just Top Up the Coolant If My Car's Coolant Is Low?

You can directly top up the coolant if your car's coolant is low, but there are some precautions to keep in mind: 1. When adding coolant, pay attention to the model and brand. Mixing different brands, models, or dosages can affect its performance. 2. When purchasing antifreeze coolant, pay attention to the freezing point of the coolant. Generally, the freezing point is around -45 degrees Celsius. It's best to choose a coolant with a freezing point at least 10 degrees lower than the lowest winter temperature in your area. 3. Be careful not to open the radiator immediately after turning off the engine. Since the cooling temperature is still high right after shutdown, there is high-pressure gas inside the radiator. Opening the radiator cap at this time can easily scald your hands or face.

What to Do About Rust on the Car Chassis?

Methods for dealing with rust on the car chassis are as follows: 1. First, remove the rust: The rust removal process is relatively simple—just polish it directly, then choose a high-quality waterproof and rust-proof coating for repair. When performing rust-proof work on the car, it's important to use the same type of paint for the best results. 2. The quality of chassis rust-proof treatment largely depends on the service center chosen by the owner. To achieve outstanding results in this protective process, it's advisable to go to a 4S shop or a more professional auto repair shop. 3. During the chassis rust-proof treatment, the uniformity of the coating is crucial. A uniform coating prevents the rust-proof paint from peeling off. After applying the rust-proof material, avoid driving the car immediately; allow it to air dry naturally for optimal effectiveness.

How to Adjust High Beam and Low Beam on a Sedan?

How to adjust high beam and low beam on a sedan is as follows: 1. For the standard of car low beam adjustment, it generally only specifies the light intensity and beam height. The low beam should illuminate the area 25-35 meters in front of the car, and the beam height should not be too high to avoid dazzling other vehicles and affecting driving safety. 2. The car low beam can be adjusted by yourself using the knob behind the headlight assembly with tools. Park the car 10 meters away from a wall, measure the distance from the low beam to the central axis, the distance from the high beam to the central axis, and the distance from the low beam to the ground; then move to the wall and mark the corresponding positions on the wall; observe whether the light beam is offset left or right, too high or too low. If the center of the headlight beam does not align with the marked point, it indicates an offset, which can be adjusted by rotating the headlight width adjustment knob to align the center of the headlight beam with the mark on the wall. 3. Generally, the headlight width is preset at the factory, and self-adjustment is not recommended. If there is an offset, fine-tuning can be done. During adjustment, the right headlight beam can be slightly adjusted to the right, which can help see the right side of the road more clearly in low visibility conditions such as rainy or foggy days. However, it is more recommended to go to a 4S shop or repair shop for standard adjustment.

How to Clean the Three-Way Catalytic Converter in a Car?

The three-way catalytic converter is an emission control device in the engine, and its proper functioning determines the engine's fuel consumption, power, and emission performance. If it becomes clogged or malfunctions, the exhaust emissions will exceed the standard. It is recommended to perform a non-dismantling cleaning, either by using the "drip method" or by adding a cleaning agent to the fuel tank. The specific steps for the "drip method" are as follows: 1. Start the engine and turn it off after the water temperature normalizes; 2. Pour the cleaning solution into a specialized device and connect the device's output to the vacuum pipe; 3. Start the engine, maintain the RPM at around 2000, open the flow control valve, and slowly drip the solution into the intake manifold for approximately 30 minutes; 4. After cleaning, keep the engine running at the same RPM for 3-5 minutes to expel any residual liquid.

What brand of engine is used in the Changan CS75?

The engine of the Changan CS75 is independently developed by Changan Automobile and belongs to a domestically produced engine. The engine model of the Changan CS75 is JL473ZQ7, with a maximum horsepower of 180, a maximum power of 132kW, and a maximum torque of 300Nm. For daily maintenance of the Changan CS75 engine, the following methods can be used: Use lubricating oil of the 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 engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, the oil should be changed regularly according to usage conditions, and the oil level should be kept moderate. When the 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, it may burst the filter element or open the safety valve, allowing the oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. 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 the cylinder wall, mixing with metal powder from component wear to form sludge. A small amount remains suspended in the oil, while a large amount precipitates, clogging the filter and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and the engine.
