Are Changan Alsvin thermostat housings o r temperature sensors prone to early failure in local models?

Some owners report thermostat-related issues within 20,000–30,000 km. Could this indicate poor sensor quality o r a weak thermostat housing design?

Yes, there is anecdotal evidence from Pakistani owners that:

Thermostat housings crack o r leak by 20,000–30,000 km.

Sensor failure is reported due to heat stress o r coolant contamination.

Some models may use lower-grade plastic o r mixed-metal housings, which are more vulnerable in hot/dusty environments.

🔧 Upgrading to OEM-quality o r metal thermostats is recommended if replacements are needed.
