Prevent Overheating in Summer Traffic Jams

Cost Savings

Checklist Tasks

• Check coolant level and mixture with a hydrometer for proper heat absorption.
• Inspect radiator fins for debris or bends to ensure maximum airflow.
• Test radiator fan by idling with A/C on to confirm fan engagement.
• Examine serpentine belt for cracks or glazing to prevent water pump issues.
• Test coolant reservoir cap for pressure retention to reduce boiling risk.
• Flush and replace coolant if rusty or cloudy to improve heat transfer.
• Check for head gasket seepage to catch leaks before overheating.
• Clean A/C condenser with low-pressure water to clear airflow obstructions.
• Monitor thermostat by watching the temperature gauge during warm-up.
• Test heater core by running heat on high for airflow and temperature.
• Carry pre-mixed coolant for emergency use in case of overheating.
• Watch dashboard warnings and set alerts to catch rising temperatures early.
