The reasons why the air outlet mode of a car's manual air conditioner cannot be turned are: 1. Foreign objects stuck; 2. Poor lubrication; 3. Control panel malfunction. The correct way to use a car's air conditioner: After the car has been exposed to the sun, when you first enter the car, you should open the windows for ventilation and turn on the external circulation to expel the hot air. After the temperature inside the car drops, switch to internal circulation. The reasons why the car's heater is not warm at idle but becomes warm when running are: 1. The thermostat is always open or opens too early, causing the car's water temperature to participate in the large circulation cooling before it rises; 2. The electric cooling fan is always running; 3. The heater core or water passage is blocked, preventing the hot coolant from entering the heater core for circulation; 4. The heater valve cannot open normally.

What does the SVS indicator on the car dashboard mean?

SVS indicator light is the engine fault indicator light. Here is more information about SVS: 1. When the SVS light is on, it indicates a fault in the fuel emission system; intake tract fault; spark plug carbon deposit; sensor fault; poor fuel quality; engine carbon deposit; three-way catalytic converter fault; engine knock. 2. When the SVS light is on, you can check whether the oxygen sensor plug is loose; clean the spark plugs; replace the oxygen sensor; replace the three-way catalytic converter; clean the engine; drain the old gasoline from the fuel tank and replace it with high-quality gasoline. 3. SVS, the full English name is Service Vehicle Soon, which translates to "service vehicle as soon as possible." The SVS light is a standard indicator in the automotive industry, responsible for warning of abnormalities in the powertrain system and prompting users to have the vehicle inspected at a service shop. When the powertrain system's self-diagnosis detects an abnormality, it will use the SVS light to prompt the user to have the vehicle inspected. The SVS light alarm may originate from the engine, transmission, or shift control mechanism. When the SVS light flashes, it represents a current fault in the powertrain system, requiring inspection at a service shop; when the SVS light stays on, it represents a historical fault (once occurred) in the powertrain system. In most cases, the historical fault will be automatically repaired by the system, and the SVS light will turn off.

What is the difference between 1.5L and 2.0L engine displacement?

The differences between 1.5L and 2.0L engine displacement are: 1. Different exhaust emissions, with 2.0L displacement vehicles emitting more exhaust than 1.5L displacement vehicles; 2. Different engine power, with 2.0L displacement engines having greater power than 1.5L displacement engines; 3. Different fuel consumption, with 2.0L displacement engines generally consuming more fuel than 1.5L displacement engines. Here is additional information: Compared to 2.0L displacement engines, 1.5L displacement engines have lower maintenance costs in the long run because 2.0L displacement engines have larger volumes, requiring more fluids to support their operation. 1.5L displacement vehicles have weaker initial acceleration but higher fuel efficiency, with fuel consumption around 6L, while 2.0L displacement vehicles have stronger power, leaning towards sportiness, but with relatively higher fuel consumption.

What Causes Clutch Shudder?

Clutch shudder can be attributed to the following main reasons: 1. Uneven pressure distribution in the car's clutch; 2. Excessive tension in the clutch pressure spring; 3. Insufficient lubrication causing stiffness in components such as the release sleeve and release fork shaft; 4. Oil contamination or breakage of the driven disc lining; 5. Warping of the main or driven disc, or uneven height of the release levers. Causes and solutions for clutch shudder: 1. Uneven pressure distribution in the car's clutch, leading to loose or broken springs and incorrect pressure positioning, causing clutch instability. Solution: Readjust the pressure distribution of the car's clutch. 2. Excessive tension in the clutch pressure spring, resulting in clutch shudder. Solution: Replace the clutch pressure spring with one of appropriate size. 3. Insufficient lubrication causing stiffness in components such as the release sleeve and release fork shaft, leading to clutch shudder. Solution: Add lubricant between the release sleeve and release fork shaft components. 4. Oil contamination or breakage of the driven disc lining, or uneven thickness of the driven disc causing shudder. Solution: Replace the damaged driven disc lining. 5. Warping of the main or driven disc, or uneven height of the release levers causing clutch shudder. Solution: Identify the fault and complete the necessary repairs.
