How does Pakistan’s hot weather affect the cooling system of the Mercedes-Benz E-Class?

Living in Pakistan, the weather often reaches extreme temperatures. I’m concerned about how this affects my Mercedes-Benz E-Class engine. Does the hot climate make the cooling system more likely to fail? What components are most vulnerable, and how can I prepare my car to handle the heat?

Pakistan’s extreme summer heat puts additional stress on your E-Classs cooling system. The main effects include:

Faster Coolant Breakdown: High ambient temperatures can cause coolant to degrade more quickly, reducing its effectiveness.

Increased Pressure on Cooling Components: Components like the radiator, hoses, and water pump are under greater strain, increasing the risk of leaks o r failures.

AC and Engine Load: Running the air conditioner continuously in hot weather adds extra load to the engine, which raises the engine temperature.

Preventive Measures:

Use high-quality coolant suitable for hot climates e.g., Mercedes-approved G48 o r equivalent.

Inspect the cooling system before summer begins.

Ensure the radiator fan and temperature sensors are working properly.
