Ford F-150 13th Generation (2015-2020) engine overheating how to fix it

Solution

1. Preparation

• Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the engine is cool.
• Tools Required:
  • OBD-II scanner
  • Coolant funnel
  • Socket set
  • Torque wrench
  • Multimeter (for fan testing)
• Safety Warnings:
  • Disconnect the battery before working on electrical systems.
  • Allow the engine to cool completely before opening the radiator cap.

2. Address Coolant Leaks

1. If coolant leaks are detected, locate the source of the leak.
2. Replace any damaged hoses or fittings.
   • Use a socket set to remove hose clamps and the affected hoses.
   • Install new hoses and secure with clamps, ensuring a tight fit.
3. If the radiator is leaking, consider a replacement or repair.
   • Drain the coolant using the drain valve at the bottom of the radiator.
   • Remove the radiator by disconnecting the upper and lower hoses, and the mounting bolts.
   • Install the new radiator and reconnect all hoses securely.

3. Replace the Thermostat

1. Remove the thermostat housing by unscrewing the bolts with a socket set.
2. Take out the old thermostat and replace it with a new one, ensuring the correct orientation.
3. Reinstall the thermostat housing and torque the bolts to manufacturer specifications (usually around 15-20 ft-lbs).

4. Check and Replace Cooling Fans

1. Test the electric cooling fans using a multimeter to ensure they are operational.
2. If they do not function, remove the fan assembly by unscrewing the mounting bolts.
3. Disconnect the wiring harness and install a new fan assembly if needed.

5. Final System Check

1. Refill the cooling system with the appropriate coolant mixture (typically a 50/50 mix of antifreeze and distilled water).
2. Bleed the cooling system to remove air pockets by running the engine with the radiator cap off until the thermostat opens, and coolant circulates.
