Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery cable to ensure safety.
  • Allow the engine to cool before working on the cooling system.
2. Check and Refill Coolant
  • Inspect the coolant reservoir and radiator for any low levels.
  • If low, add the appropriate type of coolant (refer to the owner’s manual for specifications).
  • Start the engine and let it reach operating temperature while monitoring the coolant level.
3. Thermostat Replacement (if faulty)
  • Remove the engine cover if applicable.
  • Drain a small amount of coolant from the radiator to prevent spillage.
  • Disconnect the thermostat housing by removing the bolts using a socket set.
  • Remove the old thermostat and replace it with a new one, ensuring the gasket is properly aligned.
  • Reassemble the thermostat housing and refill the coolant.
4. Heater Core Inspection
  • Locate the heater core hoses in the engine bay.
  • Disconnect the hoses from the heater core.
  • Use a garden hose to flush the heater core, ensuring clear flow in both directions.
  • Reconnect the hoses securely.
5. Bleed the Cooling System
  • With the radiator cap off, start the engine and allow it to reach operating temperature.
  • Watch for air bubbles escaping from the radiator.
  • Once bubbles stop, replace the radiator cap securely.
