Cooling system malfunction detection methods are: 1. Check if the shutters are closed or have insufficient opening; 2. Inspect the tightness of the fan belt; 3. Verify if the fan clutch is functioning normally and if the fan blade direction is correct; 4. Examine the working efficiency of the water pump. The causes of automotive engine cooling system malfunctions include: 1. Shutters being closed or having insufficient opening; 2. Slippage of the radiator fan belt or damage to the fan blades; 3. Poor performance of the temperature control switch for the electronically controlled fan; 4. Low rotational speed of the axial flow blower in the cooling system, obstructed air ducts, or poor air diversion. Cooling systems can be categorized into air-cooled and water-cooled based on the cooling medium used. A system that dissipates heat from high-temperature engine components directly into the atmosphere is called an air-cooled system, while a system that first transfers this heat to coolant and then dissipates it into the atmosphere is called a water-cooled system.

What is the function of the button on the gear shift lever of an automatic transmission car?

The function of the button on the gear shift lever of an automatic transmission car is: 1. To prevent the driver from accidentally shifting gears and causing accidents; 2. To protect the transmission, prevent damage to the transmission gears, and prolong the service life of the transmission. The automatic transmission gears include: 1. P gear, parking gear; 2. R gear, reverse gear; 3. N gear, neutral gear; 4. D gear, drive gear; 5. L gear, low gear. Automatic transmission cars are equipped with an automatic transmission, whose working principle is to automatically shift gears based on the vehicle speed, engine speed, and power load through the coordination of the torque converter and gear transmission system. The hydraulic control device adjusts the shifting timing by controlling the transmission fluid volume according to the throttle opening degree.

What is the normal range for oil pressure?

Automotive oil pressure typically ranges between 284-325 kPa (41-47 psi). Installed inside the fuel tank and connected to the fuel delivery assembly, the electric fuel pump delivers fuel through the pipeline filter to the fuel rail assembly. The fuel pump is designed to provide fuel pressure higher than the regulated pressure required by the injectors, with excess fuel returning to the tank via the return line. The fuel pump test terminal is located in the engine compartment; when the engine is off, applying battery voltage to the test terminal can start the fuel pump. Below are additional details about oil pressure: 1. The oil pressure regulator is a diaphragm-controlled overflow valve. 2. When the fuel chamber pressure exceeds the combined force of the spring pressure and vacuum pressure, the diaphragm arches upward, opening the regulator valve and allowing fuel to flow back to the tank through the return port via the ball valve.

Why Must Cars Have Their Engine Oil Changed?

Cars need engine oil changes for the following reasons: 1. To improve and enhance lubrication for moving friction components in the engine. 2. To extend the engine's service life. 3. To optimize the engine's lubrication conditions and reduce friction between moving parts. Steps for changing engine oil: 1. Lift the vehicle, remove the underbody shield, and place a container with approximately 10-liter capacity beneath the drain plug. 2. Loosen the drain plug, use an air gun to blow into the oil filler opening for two minutes. After complete drainage, tighten the drain plug and wipe it with a tissue to check for leaks. 3. Reinstall the underbody shield, lower the vehicle, and use a funnel to add new oil through the filler opening.
