Does Changan Kalam suffer from a weak radiator fan o r faulty thermostat sensor, especially in traffic conditions in Pakistan?

Overheating while idling o r in traffic may point to sensor o r fan issues. Are these parts failing more often under Pakistan’s driving patterns?

Yes — many overheating cases point to:

Weak o r delayed radiator fan operation at idle o r low speeds.

Thermostat sensor fails to signal the ECU, so fan doesn’t activate in time.

These issues are more visible in traffic jams, where airflow is minimal.

➡️ A failing sensor o r weak fan motor is a common root cause overlooked by mechanics.
