- Ensure the coolant level in the reservoir is between the "Full" and "Add" marks.
2. Faulty Thermostat
- A stuck thermostat can prevent coolant from circulating properly, causing the engine to overheat.
3. Water Pump Failure
- A faulty water pump can reduce coolant circulation, leading to overheating.
4. Leaking Head Gasket
- A leaking head gasket can allow coolant to enter the combustion chambers, causing overheating.
5. Blocked Radiator
- A clogged up radiator with dirt or debris can hinder its cooling ability.
6. Faulty Fan or Fan Clutch
- A non-functioning fan or fan clutch can reduce airflow, compromising engine cooling.
7. Air in the Cooling System
- Air pockets trapped in the cooling system can cause overheating.
8. Faulty Radiator Cap
- A faulty radiator cap can prevent the cooling system from building up pressure, causing overheating.
9. Faulty Temperature Sensor or Gauge
- If these components are defective, they may provide incorrect readings, masking an underlying issue.
10. Fuel Injection Issues
- Lean fuel mixtures can cause the engine to run hotter.
