• Disconnect the battery to prevent any electrical issues.

2. Coolant Level and Inspection

• Sub-steps:
  1. Open the hood and locate the coolant reservoir.
  2. Check the coolant level; if low, add a 50/50 mix of coolant and distilled water.
  3. Inspect for visible leaks around hoses and connections.

3. Thermostat Replacement (if faulty)

• Tools Required: Socket set, torque wrench, gasket scraper
• Sub-steps:
  1. Drain the coolant from the radiator into a container.
  2. Remove the thermostat housing by unscrewing the bolts.
  3. Remove the old thermostat and clean the mating surfaces.
  4. Install the new thermostat with the correct orientation.
  5. Reattach the housing and torque to manufacturer specifications.

4. Cooling Fan Testing or Replacement

• Tools Required: Multimeter, socket set
• Sub-steps:
  1. Reconnect the battery.
  2. Start the engine and let it reach operating temperature.
  3. Use a multimeter to check for power to the fan motor when the engine heats up.
  4. If the fan does not engage, replace it with a new unit.

5. Radiator and Hose Inspection

• Sub-steps:
  1. Remove any debris obstructing the radiator.
  2. Examine hoses for bulges or leaks and replace any damaged hoses.
  3. Flush the radiator with a garden hose if there are blockages.
