1 Answers
Engine water pump failure manifests in the following ways: 1. Unstable engine idle speed; 2. Water leakage near the water pump area of the engine; 3. Abnormal noises from the engine compartment; 4. Elevated engine coolant temperature that fails to decrease. Working principle of engine water pump: The engine drives the water pump bearing and impeller via the pulley, causing the coolant to be flung towards the edge of the pump housing by the impeller, then flowing out through the water outlet or hose. The automotive water pump consists of components including the pump housing, connecting flange or pulley, pump shaft and bearings (or integrated shaft bearings), impeller, and sealing device, constituting a major component of the vehicle.
