What Causes Water Pump Dripping?

Water pump dripping is caused by: 1. Poor sealing; 2. Damaged sealing gasket; 3. Internal leakage in the heater. The working principle of an automotive water pump is: The engine drives the water pump bearing and impeller via the pulley, causing the coolant in the water pump to rotate along with the impeller. Under centrifugal force, the coolant is thrown toward the edge of the water pump housing, generating a certain pressure before flowing out through the outlet channel or hose. The center of the impeller experiences reduced pressure as the coolant is thrown outward, allowing coolant from the radiator to be drawn into the impeller through the hose due to the pressure difference between the pump inlet and the impeller center, thus achieving a reciprocating cycle of the coolant.

Is Transmission Oil Leakage Serious?

Transmission oil leakage is serious and requires timely repair. The impacts of excessive transmission oil include: 1. Increased operational resistance inside the transmission, leading to abnormal oil leakage; 2. Agitation of the oil by rotating components can cause foaming; 3. Abnormal oil pressure may lead to air blockage in the drain holes of the control valve, resulting in poor drainage; 4. Gear shifting may become harsh. Precautions for changing transmission oil: 1. Choose the appropriate viscosity to avoid power loss; 2. Do not mix different types of oil to prevent adverse effects on the vehicle; 3. Avoid using low-quality transmission oil; 4. Ensure no impurities are introduced during the transmission oil change process.
