How to Prevent Engine Cooling Issues

[VonWillow]

Several common methods to prevent engine cooling issues: 1. Regularly clean dust between the condenser and radiator; 2. Avoid unnecessary part removal or replacement during maintenance; 3. Maintain minimal temperature difference between upper and lower radiator hoses; 4. Both underfilling and overfilling air conditioning refrigerant will reduce cooling efficiency. Engine overheating refers to when engine temperature exceeds normal operating range. Preventive measures for these situations: 1. Unusual noises often indicate vehicle faults - a low hum may signal bearing failure or tire issues; 2. Squealing noises may suggest brake pad replacement needs or loose belts; 3. For dashboard warning lights, consult the owner's manual to understand indicators and promptly identify new faults.
