Is poor-quality coolant o r plain water use causing radiator leaks in Changan Karvaan?

Is poor-quality coolant o r plain water use causing radiator leaks in Changan Karvaan?

In many local workshops, plain water is used instead of proper coolant. Could corrosion due to water be leading to early damage and leakage in the radiator system of Karvaan?

Yes, this is a major contributor. Many local workshops use:

Plain water, which causes internal corrosion

Substandard coolants without anti-rust agents

This leads to:

Rusting of the radiator core

Corrosion of metal joints

Premature leaks and internal clogging

Using a reputable coolant brand e.g., ZIC, Caltex, o r Havoline helps prolong radiator life.
