Are Changan Karvaan radiator pipes and hoses prone to early wear and cracks in Pakistan’s heat?

Pakistan’s extreme summer temperatures can cause rubber parts to harden and crack. Are radiator hose failures common in Karvaan, and could this be leading to unnoticed coolant leaks?

Yes. Pakistans extreme temperatures up to 45°C+ can cause:

Rubber hoses to harden and crack

Expansion and contraction stress, especially during hot-cold cycles

Radiator hoses in Karvaan are particularly vulnerable when:

Low-quality parts are installed

The van is regularly overloaded
Frequent inspections and using heat-resistant silicone hoses help prevent failures.
