TECHNICAL CHECK
Cooling Fan, Thermostat and Water Pump Diagnostic Check
Overheating is not always a fan fault. Thermostat, pump, sensor, trapped air and coolant circulation may all need evaluation.
What is reviewed?
- Fan activation behaviour
- Fan power/control circuit where required
- Possible thermostat malfunction
- Water-pump/circulation symptoms
- Air in system and coolant level
Model-specific limit: Fan activation temperature and thermostat values are model-specific.
