• Monitor Engine Temperature: Keep an eye on the engine temperature gauge while operating the machine. If the temperature starts to rise, stop and check the cooling system before continuing work.
  
• Scheduled Belt Replacements: Replace the belts on a regular schedule, even if they appear to be in good condition. Over time, belts can stretch or weaken, leading to cooling system failures.
  
• Inspect Thermostat and Water Pump: During regular maintenance, inspect the thermostat and water pump for signs of wear. Replacing these components at the first sign of malfunction can prevent overheating down the line.
