Are overheating problems common in Changan Kalam during long-distance hauling in hot Pakistani climates?

Drivers from southern regions like Sindh and Balochistan complain about rising engine temperatures. Could this be due to a weak cooling system o r low-grade coolant?

Yes. Overheating is frequently reported, especially in:

Sindh

Balochistan

South Punjab

Reasons include:

A small radiator that’s not efficient for prolonged heat dissipation under load

Use of cheap coolant o r just water, which lacks thermal stability

Clogged radiator fins due to dusty roads and lack of periodic flushing

Weak fan motor that doesn’t cool properly at low RPMs in traffic

If the vehicle is hauling cargo in 40°C+ weather, this weak cooling setup often fails.
