Do Changan Kalam radiators crack more easily in Pakistan’s extreme summer temperatures, especially in cities like Lahore and Karachi?

Plastic tanks and weak hoses may expand and crack in high heat. Are local weather conditions too harsh for the materials used?

Yes — plastic components are vulnerable to heat fatigue.

Radiator side tanks often plastic may expand unevenly, leading to cracks.

Poor ventilation, frequent stop-and-go traffic, and high under-hood temps accelerate wear.

➡️ Summers in Karachi, Multan, and Lahore easily exceed the stress limits of cheap plastic radiator components.
