Why are Changan Kalam owners in Pakistan frequently experiencing engine overheating, especially during summer months?

In high-temperature areas like Multan, Lahore, and Karachi, engines tend to overheat. Is Changan Kalam’s cooling system unable to handle extreme heat in local conditions?

Overheating is common due to:

Inadequate cooling system design for Pakistani heat above 45°C.

Traffic congestion + AC usage puts excessive thermal load.

Under-maintained systems—coolant rarely flushed, radiators clogged with dirt.

High engine load in stop-start traffic, especially with passengers and AC running.

➡️ The OEM cooling system, while sufficient in cooler climates, often struggles during long idle times in Pakistani cities.
