Why do some Changan Karvaan units experience heating issues during long trips o r in summer traffic?

Overheating complaints arise in cities like Multan o r interior Sindh. Is the cooling system undersized for Pakistan’s hot climate?

Common reports from areas like Multan, Sindh, and southern Punjab mention:

Engine temperature rising during prolonged idling o r slow traffic.

Reduced AC performance when vehicle is heating.

Possible causes:

Undersized radiator o r fan for Pakistans harsh summers above 45°C.

Poor coolant maintenance.

Some units lack an engine temperature gauge, making early detection harder.

➡️ The cooling system is borderline adequate, and long trips with AC in extreme heat often expose this weakness.
