why does my Ford F-150 Fourteenth Generation (2021-present) overheat in traffic

Solution

1. Preparation

• Gather tools and parts.
• Ensure the engine is cool before starting work.
• Disconnect the negative battery terminal for safety.

2. Check and Refill Coolant

• Sub-steps:
  • Locate the coolant reservoir and radiator cap.
  • Open the radiator cap carefully, releasing any pressure.
  • Check the coolant level; if low, add the appropriate coolant mixture (50% water and 50% ethylene glycol).
  • Replace the radiator cap securely.

3. Replace Thermostat

• Sub-steps:
  • Remove any covers obstructing access to the thermostat housing.
  • Disconnect the hoses connected to the thermostat housing.
  • Unbolt and remove the thermostat from its housing.
  • Replace it with a new thermostat, ensuring the correct orientation.
  • Reattach hoses and secure them with clamps.

4. Inspect and Replace Radiator Fan

• Sub-steps:
  • Test the radiator fan operation by connecting it directly to the battery (if safe).
  • If the fan does not operate, remove it from the vehicle.
  • Install a new radiator fan, ensuring all electrical connections are secure.

5. Check Water Pump

• Sub-steps:
  • Inspect the water pump for any coolant leaks or noise.
  • Remove the serpentine belt and check if the pump spins freely.
  • Replace the water pump if it shows signs of failure.

6. Test the Cooling System

• Sub-steps:
  • After repairs, refill the cooling system and bleed any air trapped.
  • Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
  • Conduct a test drive to confirm that the overheating issue is resolved.
