Is Changan Kalam’s coolant reservoir o r radiator cap known to fail o r leak in Pakistan’s harsh climate?

Faulty caps can release pressure and cause the engine to overheat. Are these components durable enough for Pakistan’s roads and heat?

Yes, these parts can fail early due to:

High ambient heat + pressure buildup cracking plastic reservoirs.

Radiator cap’s spring valve wears out, causing:

Coolant to overflow

Loss of system pressure

Early overheating

➡️ These are inexpensive but critical components — replace every 1–2 years o r at the first sign of weakness.
