How many kilometers should the Jetta water pump belt be replaced?
1 Answers
Jetta water pump belt should be replaced at around 80,000 kilometers. Automotive engines widely use centrifugal water pumps, whose basic structure consists of the water pump housing, connecting disk or pulley, water pump shaft and bearings or integrated bearing, water pump impeller, and water seal device, among other components, making it a major part of the vehicle. Symptoms of a damaged water pump: 1. A damaged water pump can weaken or even stop the cooling circulation, leading to coolant boiling; 2. Leakage near the water pump area of the engine. Coolant leakage will leave traces of coolant color on the water pump vent holes, resulting in symptoms like high water temperature due to insufficient coolant; 3. Unusual noises from the water pump while the engine is running.
