01Check Coolant Level

  • Start by parking the motor grader on a level surface and engaging the parking brake.
  • Allow the engine to cool down before opening the coolant reservoir.
  • Locate the coolant reservoir, typically a translucent plastic tank near the radiator.
  • Check the coolant level by looking at the markings on the side of the reservoir.
  • If the coolant level is below the minimum mark, it needs to be topped up.

02Inspect Hoses and Connections

  • Visually inspect all the hoses and connections in the coolant system for signs of leaks, cracks, or damage.
  • Ensure that all the connections are tight and secure.
  • If you notice any leaks or damage, replace the affected hoses or connectors.
  • Tighten any loose connections using appropriate tools.

03Flush and Replace Coolant

  • Consult the motor grader's owner's manual to determine the recommended coolant flush interval.
  • If the coolant hasn't been flushed within the recommended interval, it's time to do so.
  • Drain the old coolant by locating the drain valve at the bottom of the radiator.
  • Collect the drained coolant in a suitable container and dispose of it properly.
  • Flush the coolant system with water to remove any remaining debris or contaminants.
  • Once the system is flushed, refill it with the appropriate coolant mixture as specified in the owner's manual.

04Inspect Radiator and Fan

  • Inspect the radiator and fan for any dirt, debris, or obstruction.
  • Clean the radiator using compressed air or a soft brush to remove any build-up of dirt or debris.
  • Ensure that the fan blades are clean and free of any debris.
  • If necessary, use a suitable cleaner to remove any stubborn dirt or grime from the radiator and fan.
  • Ensure proper airflow through the radiator and fan to prevent overheating.

05Check Belts and Tension

  • Inspect the belts that drive the coolant pump and fan for signs of wear, cracks, or damage.
  • Check the tension of the belts by pressing on them with moderate force. They should have a slight give.
  • If the belts are loose, tighten them according to the motor grader's specifications.
  • If the belts are worn or damaged, replace them with new ones.

06Regularly Monitor Temperature

  • Start the motor grader and let it idle for a few minutes.
  • Monitor the temperature gauge or warning light for any abnormal readings.
  • If the engine temperature rises above the normal range, there may be an issue with the coolant system.
  • Investigate and resolve any cooling system problems promptly to prevent engine damage.

Conclusion

By following these maintenance steps, you can ensure the proper functioning and longevity of the engine coolant system of your motor grader. Regular checks and timely repairs or replacements will help prevent costly breakdowns and extend the life of your equipment.
