Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery negative terminal to prevent electrical issues.
2. Coolant Level Check
  • Open the coolant reservoir cap carefully to relieve any pressure.
  • If low, add the appropriate type of coolant (refer to the owner's manual for specifications).
3. Leak Repair
  • Identify and replace any damaged hoses or components by:
    • Loosening hose clamps with a screwdriver.
    • Removing the damaged hose and replacing it with a new one.
    • Tightening hose clamps securely.
4. Radiator Fan Inspection
  • Start the engine and allow it to reach normal operating temperature.
  • Monitor the radiator fan operation; if it does not engage:
    • Check the fan motor by applying direct power to it.
    • Replace the fan motor if it fails to operate.
5. Thermostat Replacement
  • Drain the coolant from the radiator.
  • Remove the thermostat housing bolts using a socket set.
  • Take out the old thermostat and replace it with a new one.
  • Reassemble the housing and refill the cooling system with coolant.
6. Final Checks
  • Reconnect the battery terminal.
  • Start the engine and let it idle while monitoring for leaks.
  • Perform a test drive to ensure the issue is resolved.
