What Causes the Damage to Volkswagen's Water Pump?
1 Answers
Automobile water pump damage can be attributed to the following reasons: 1. Unstable idling: Water pump malfunction can increase the rotational resistance of the pump. Since the water pump is connected to the timing belt, increased rotational resistance can directly affect the engine's operation. During idling, this manifests as fluctuations in RPM after starting, which is more noticeable in winter and may even lead to stalling. 2. Engine usage issues: Abnormal noises from the engine water pump, which are friction sounds during rotation. These sounds can intensify with increased engine speed and vary in volume. Typically, such noises become more pronounced as the fault worsens. Experienced mechanics should be able to identify this issue. 3. Cooling system malfunctions: This encompasses a series of fault phenomena, such as insufficient coolant, scale buildup in the coolant, or a thermostat failing to open, all of which can lead to water pump failure and damage.
