What are the reasons for water pump leakage in Skoda Superb?

[DeTheo]

Skoda Superb water pump leakage reasons are as follows: Inadequate water pump sealing: Inadequate water pump sealing can easily cause coolant leakage. The coolant will directly seep into the water pump bearing, washing away the lubricant on the bearing, which may damage the water pump bearing over time. External leakage: The main causes of external leakage include hardening of engine seals and gaskets due to long-term use, internal leakage in the heater or leakage in the oil cooler. In this case, it is necessary to troubleshoot one by one and leave it to professionals. Water pump freezing and cracking: Water vapor condensation in the cooling system freezes, causing the water pump body to freeze and crack.
