1. Fan and Belts Inspection: Inspect the cooling fan and belts connected to the engine cooling system. The fan should rotate freely and the belts should be in good condition, with the correct tension. Replace any worn or damaged belts and ensure the fan is functioning properly.
2. Thermostat Check: The thermostat regulates the flow of coolant through the engine. If there are issues with engine overheating, the thermostat may need to be inspected and tested. A faulty thermostat should be replaced.
3. Case 821G 921G Regular Maintenance: Follow the manufacturer’s recommended maintenance schedule for the engine cooling system. This may include periodic coolant flushes, replacement of hoses and clamps, and other specific maintenance tasks.
