What Needs to Be Maintained During the First Car Service?

The items that need to be maintained during the first car service include: 1. Inspect the engine's working condition, such as whether the pipe connections are normal, if there are any leakage points, whether the engine sounds normal during operation, and if there are any abnormal noises; 2. Check if the coolant level is within the normal range; 3. Examine the wear level of the brake pads and tires, as well as the tire pressure condition; 4. Inspect the chassis components for any scratches or corrosion; 5. Check the remaining amount of power steering fluid and whether there are any oil leakage signs at the oil pipe interfaces; 6. Perform a comprehensive cleaning of the vehicle, including the engine compartment, body, and interior. New cars generally undergo their first service after driving 3,000 to 5,000 kilometers or 3 to 5 months. After the first service, regular maintenance is also necessary, including periodic oil changes, replacement of various filters, and checking tire conditions and brake pad wear.

What are the consequences of forgetting to release the handbrake in an automatic transmission car?

Consequences of forgetting to release the handbrake in an automatic transmission car: 1. It will accelerate the wear of the brake discs, and the brake pads will also harden due to overheating, reducing the performance of the handbrake and causing the handbrake cable to stretch; 2. Driving for a long time without releasing the handbrake can cause the brake caliper to seize, leading to brake fluid leakage and an increase in the temperature of the brake fluid, ultimately causing the handbrake's braking function to completely fail; 3. Forgetting to release the handbrake for an even longer period may result in a burning smell, and in severe cases, smoke may even appear from the rear of the car. Driving with the handbrake engaged can also cause some damage to the vehicle's tires. The faster the speed, the greater the damage to various components. Nowadays, many cars are equipped with electronic handbrakes, which are relatively better because the system will automatically release the handbrake when wheel speed sensors detect wheel rotation, thus avoiding the situation of driving with the handbrake engaged.

How to Calculate SUV Fuel Consumption?

For general household SUVs, a fuel consumption of 10L-15L/100km is considered normal. The fuel consumption of a car is related to factors such as engine displacement, engine type, vehicle weight, and car design. Here are the factors that affect fuel consumption: 1. Engine Displacement: Generally, SUVs have higher engine displacement compared to family sedans. The larger the engine displacement, the higher the fuel consumption. 2. Vehicle Design: Fuel consumption is related to the vehicle's design. Typically, SUVs have a larger body size and higher profile than sedans, which increases wind resistance during driving, leading to higher fuel consumption. 3. Tires and Tire Pressure: Different tires and tire pressures result in varying rolling resistance. Lower tire pressure increases rolling resistance, which in turn increases fuel consumption. 4. Lack of Proper Maintenance: Improper vehicle maintenance can lead to increased fuel consumption. Issues such as incorrect wheel alignment, dirty air filters, and delayed oil changes can all affect the car's fuel efficiency.

What is the lifespan of a Suzuki Swift engine?

Suzuki Swift engines can typically operate for 10 years or 300,000 kilometers without requiring major repairs under normal conditions. The selection of load, fuel, and lubricating oil can affect the engine lifespan to varying degrees. Below are relevant factors influencing engine lifespan: Impact of load selection on engine lifespan: Engine load directly affects the strength and lifespan of its components. Increasing the load raises the working stress on various assemblies, leading to greater wear. For run-in vehicles, the wear can be even more significant. New vehicles or those that have undergone major repairs often have speed limiters installed on their carburetors to restrict maximum speed during the run-in period, reduce load, and extend engine lifespan. Premature removal of these limiters can result in early occurrences of abnormal noises, oil leaks, air leaks, and reduced power, shortening the engine's service life. Impact of fuel and lubricating oil selection on engine lifespan: The fuel used must meet the specified grade for the vehicle. Using lower-grade fuel is prohibited as it can cause engine knocking, subjecting components to intense impacts and additional loads, thereby accelerating wear. The high temperatures, pressures, and shock waves generated by knocking can also destroy the lubricating oil film on cylinder walls, worsening component lubrication. Tests show that an engine operating for 200 hours with knocking exhibits more than twice the average wear in the upper cylinder compared to one operating without knocking. Additionally, fuel with excessive impurities can accelerate component wear and corrosion.

What's the matter if the car fan doesn't rotate?

If the car fan doesn't rotate, the first thing to check is whether the coolant temperature has reached the required level. The fan will only rotate when the coolant temperature reaches the specified level; it won't rotate at lower temperatures. If the coolant temperature has reached the required level but the fan still doesn't work properly, it might be due to a faulty relay in the fan. In this case, you should visit a 4S shop or a repair shop to have it fixed by professionals. Another possible issue could be with the thermostat switch. If the thermostat switch malfunctions, it won't be able to control the fan's start and stop. How the car fan works: Based on the water temperature and engine load, signals are sent to the computer. The engine computer controls the high and low-speed relays of the fan, which is also influenced by the air conditioning pressure. The principle is as follows: the air conditioning computer receives signals from the air conditioning pressure switch, indoor and outdoor temperatures, etc., and then transmits the air conditioning signal to the engine computer via the bus. Upon receiving the signal to activate, the engine controls the compressor and simultaneously engages the fan relay. When the air conditioning pressure increases due to environmental or internal factors, the engine computer receives the signal from the air conditioning computer and engages the high-speed fan relay, causing the fan to operate at high speed. The role of the car cooling fan: Most of its functions are used for engine cooling and coolant cooling, ensuring that the engine does not malfunction due to high temperatures. In high-temperature working environments, the engine must be properly cooled to maintain it at a suitable operating temperature, meeting the requirements for good engine performance, durability, and exhaust emissions. The engine cooling system plays a key role here. The radiator serves both as a water storage and cooling function. The car radiator cap is equipped with an air vapor valve and has a common vent connected to the atmosphere. When the water temperature rises, the coolant in the car radiator expands, increasing the vapor pressure, and the vapor valve opens to release the vapor. When the water temperature drops, the pressure decreases, and the air valve opens, allowing outside air to enter the radiator through the common vent, thereby maintaining constant pressure inside the radiator. The radiator is the main part of the cooling system, designed to protect the engine from damage caused by overheating.
