why is my Ford F-150 13th Generation (2015-2020) engine overheating?

Solution

1. Preparation

• Gather tools and parts needed.
• Ensure the vehicle is on a level surface and the engine is cool before beginning work.
• Disconnect the battery.

2. Check and Refill Coolant

• Sub-steps:
  1. Open the coolant reservoir and radiator caps (if applicable).
  2. Inspect the coolant for color and consistency; replace if dirty.
  3. Refill with manufacturer-recommended coolant mixture (50/50 water and antifreeze).
• Tools Required: Coolant funnel
• Safety Warnings: Never open the radiator cap while the engine is hot to avoid burns.

3. Inspect and Replace Thermostat

• Sub-steps:
  1. Remove the thermostat housing by loosening the bolts with a socket set.
  2. Take out the old thermostat and inspect for damage.
  3. Install the new thermostat, ensuring the correct orientation.
  4. Reattach the housing and tighten the bolts to the manufacturer's torque specifications.
• Tools Required: Socket set, torque wrench
• Safety Warnings: Ensure engine is cool before working on cooling system.

4. Check and Replace Water Pump (if needed)

• Sub-steps:
  1. Drain the coolant from the system into a suitable container.
  2. Remove any components obstructing access to the water pump (e.g., belts, pulleys).
  3. Remove the water pump mounting bolts and take out the old pump.
  4. Clean the mounting surface on the engine.
  5. Install the new water pump with a new gasket, tightening bolts to the specified torque.
• Tools Required: Socket set, gasket scraper, coolant drain pan
• Safety Warnings: Ensure the engine is cool and the battery is disconnected.

5. Test Radiator Fan Operation

• Sub-steps:
  1. Start the engine and allow it to reach operating temperature.
  2. Observe the radiator fan for proper engagement (should turn on as the engine heats).
  3. If the fan does not engage, check the relay and wiring; replace as necessary.
• Tools Required: Multimeter
• Safety Warnings: Keep hands clear of moving parts.
