How to Determine Engine Water Pump Failure?
1 Answers
Methods to determine engine water pump failure: 1. Unstable engine idle speed; 2. Water leakage near the water pump area of the engine; 3. Noise from the engine area; 4. Increased engine coolant temperature that does not drop. Working principle of the engine water pump: The engine drives the water pump bearing and impeller through the pulley, causing the coolant to be thrown by the impeller towards the edge of the water pump housing, then flowing out through the water outlet or hose. The automotive water pump consists of the water pump housing, connecting plate or pulley, water pump shaft and bearing or integrated bearing, water pump impeller, and water seal components, and is a major part of the vehicle.
