Ignoring proper insulation in winter can do more harm than expected. One of the most common cold-weather mistakes is engine overcooling, which may quietly reduce performance and significantly shorten engine life.

❌ Common Mistake

Operating equipment in winter without cold-protection devices and failing to check whether the thermostat is functioning properly.

⚠ Serious Consequences

Excessive cooling of the diesel engine can lead to:

• Reduced engine power
• Poor combustion efficiency
• Accelerated wear and significantly shortened engine lifespan

✅ Correct Practice

• In cold northern regions, always install winter protection equipment such as engine insulation covers or thermal curtains
• Inspect the thermostat before winter begins, and replace it promptly if malfunctioning

Proper thermal management is a key part of winter maintenance. Keeping the engine within its optimal temperature range helps maintain power, efficiency, and long-term reliability—building a solid protective barrier for your equipment throughout the cold season.
