Why are Changan Kalam owners in Pakistan experiencing early water pump failure even in low-mileage vehicles?

Several users complain that the water pump starts leaking o r malfunctioning well before expected. Is this due to low build quality o r harsh local conditions?

Yes, early water pump failure is a reported issue even below 40,000–60,000 km. Possible causes include:

Low-quality OEM water pumps that use weaker bearings and seals.

Harsh driving conditions: high engine loads, stop-start traffic, and extreme temperatures stress the cooling system.

Infrequent coolant maintenance, especially in hot areas like Lahore, Karachi, and Multan, accelerates wear on seals and impellers.

Incorrect installation o r belt tension may also contribute to premature failure.
