Is poor heat management in the engine bay causing Changan Karvaan ignition coils to overheat and fail in cities like Karachi, Multan, o r Sukkur?

Extreme temperatures can degrade coil performance. Are heat shields o r ventilation systems insufficient in this model?

Yes, especially in hotter regions like Karachi, Multan, and Sukkur:

Under-hood temperatures often exceed 100°C, especially in slow-moving traffic.

Lack of heat shielding o r adequate air ventilation in the engine bay allows coils to run too hot.

Prolonged exposure to heat weakens internal coil windings and breaks down insulation.

⛔ Conclusion: Inadequate thermal protection is accelerating coil degradation in hot cities.
