What are the symptoms of a faulty car water pump?
1 Answers
When a car's water pump fails, it mainly exhibits the following symptoms: 1. The engine coolant temperature rises and does not decrease; 2. Water leakage occurs near the water pump area of the engine; 3. Unusual noises come from the water pump area after starting the engine. Here is some relevant information about water pumps: 1. Automotive engines widely use centrifugal water pumps. Their basic structure consists of components such as the water pump housing, connecting flange or pulley, water pump shaft and bearings or integrated shaft bearings, water pump impeller, and seal assembly, making them a major component of the vehicle. 2. They are generally driven by the engine's crankshaft via a V-belt. The drive belt wraps around the crankshaft pulley and the water pump pulley, causing the water pump shaft to rotate as the crankshaft turns. The water pump shaft then drives the impeller to rotate, thereby converting mechanical energy into hydraulic energy.
