Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the engine is cool to avoid burns.
  • Disconnect the battery to prevent electrical shorts.
2. Check Coolant Level
  • Locate the coolant reservoir and remove the cap.
  • Inspect the level; if low, refill with the appropriate type of coolant (Toyota Long Life Coolant).
  • If no leaks are found, proceed to the next step.
3. Inspect for Leaks
  • Visually inspect the heater core area and hoses for any signs of coolant leaks.
  • If leaks are found, replace the damaged components (e.g., heater core or hoses).
4. Test Thermostat
  • Locate the thermostat housing and remove it.
  • Inspect the thermostat for proper operation (it should open at the specified temperature, typically around 180-190°F).
  • Replace the thermostat if it is stuck closed.
5. Flush Heater Core
  • Disconnect the inlet and outlet hoses from the heater core.
  • Use a garden hose to flush the heater core with water until clear.
  • Reconnect the hoses securely.
6. Refill Cooling System
  • Refill the cooling system with the appropriate coolant mixture.
  • Bleed air from the system by running the engine with the radiator cap off until the thermostat opens.
7. Reconnect Battery
  • Reconnect the battery and ensure all electrical connections are secure.
