Is the plastic top of the Alsvin’s radiator prone to cracking in Pakistans extreme weather conditions?

In hot areas like Karachi, Multan, and interior Sindh, several users have reported that the plastic section of the radiator gets brittle and cracks. Is this a heat-resistance issue?

Yes. The plastic top tank tends to:

Harden and become brittle due to high ambient temperatures in cities like Karachi, Multan, o r Bahawalpur

Crack at seams due to repeated heat cycling and engine bay vibrations

This issue isn’t unique to Changan, but Alsvin’s radiator plastic quality is below par compared to Japanese rivals.
