What causes a purge control valve failure in my Suzuki Alto in Pakistan’s hot climate?

With the extreme heat in Pakistan, I’m concerned that the purge control valve in my Suzuki Alto might fail sooner than expected. Could the high temperatures be contributing to problems with the purge control valve? What common environmental factors in Pakistan affect the purge control valve’s performance, and how can I prevent this issue in the long run?

The hot climate in Pakistan can certainly contribute to purge control valve failure due to the following reasons:

Heat Exposure: High temperatures can cause the valve’s seals and rubber components to wear out faster. The heat can cause these parts to crack o r degrade, affecting their ability to function properly.
Increased Vapor Pressure: In hot weather, fuel vapors expand and put extra pressure on the evaporative emission system. If the purge valve isn’t functioning properly, the excess pressure can damage it over time.
Dust and Debris: Dust and dirt in the air, common in hot, dry climates, can clog the purge control valve and interfere with its normal operation.
To prevent these issues:

Regularly inspect and clean the valve to avoid blockages.
Consider using fuel additives to reduce carbon buildup in the EVAP system.
Check the condition of the valve and its seals during routine maintenance, especially before the hot summer months.
