Is thermostat failure a common reason for overheating in Changan Alsvin on Pakistani roads?

Several Alsvin users in Pakistan experience overheating in summer traffic. Could thermostat jamming either open o r closed be a leading cause? Are there patterns related to driving conditions o r coolant quality?

Yes, especially in urban traffic and hot climates like in Pakistan. Common causes include:

Stuck-closed thermostat, preventing coolant from circulating to the radiator.

Low coolant quality, leading to scale o r rust deposits jamming the thermostat.

Pattern: Overheating is most frequent in stop-and-go traffic during peak summer months when airflow is low and AC usage is high.
