How often are Changan Karvaan water pumps failing, and could this be linked to overheating?

Some users report water pump malfunction in relatively new Karvaan models. If coolant circulation is compromised due to a faulty pump, could this be a widespread issue?

Some owners report premature water pump failure—even under 40,000 km—likely due to:

Low-quality coolant o r plain water use

Poor-quality pump seals o r bearings

High engine temperatures

A faulty pump reduces coolant circulation, causing the engine to overheat quickly. It’s a contributing factor but not the most common root cause.
