Common Engine Problem and Solution
Problem: Engine Overheating
Details: Engine overheating is a common issue in construction machinery. It can be caused by several factors, including a low coolant level, a faulty thermostat, a clogged radiator, a broken water pump, or a leaking hose.
Solution:
Check Coolant Level: Ensure the coolant level in the radiator and expansion tank is within the recommended range. If low, add the appropriate coolant mixture.
Inspect Thermostat: A malfunctioning thermostat can prevent proper coolant circulation. If suspected, replace the thermostat.
Clean Radiator: A clogged radiator restricts airflow and reduces cooling efficiency. Clean the radiator fins with compressed air or water. Remove any debris.
Check Water Pump: A faulty water pump won't circulate coolant effectively. Inspect for leaks or unusual noises. If the pump is not functioning correctly, replace it.
Examine Hoses: Check all engine hoses for leaks, cracks, or swelling. Replace any damaged hoses, including the HOSE;AIR if it's involved in the cooling system (though typically it's for air intake or other systems).
Check for Air Leaks: Ensure there are no air leaks in the cooling system, which can hinder proper pressurization and cooling.
