Solution

1. Preparation

• Gather necessary tools and parts.
• Allow the engine to cool before starting any work.
• Disconnect the battery to ensure safety while working on electrical components.

2. Coolant Level Adjustment

• Sub-steps:
  1. Open the hood and locate the coolant reservoir.
  2. If necessary, add the appropriate type of coolant (Toyota Genuine Super Long Life Coolant).
  3. Secure the reservoir cap back on.

3. Replace Thermostat (if faulty)

• Sub-steps:
  1. Drain coolant from the radiator using a pan to catch the fluid.
  2. Remove the thermostat housing bolts using the socket set.
  3. Take out the old thermostat and clean the mating surfaces.
  4. Install the new thermostat and torque the bolts to the manufacturer's specification (typically around 10-15 ft-lbs).
  5. Refill the cooling system with the proper coolant mixture.

4. Repair or Replace Radiator Fan (if malfunctioning)

• Sub-steps:
  1. Inspect the fan motor and wiring for damage.
  2. If defective, disconnect the fan harness and remove the mounting bolts.
  3. Install the new fan assembly and reconnect the harness.
  4. Recheck fan operation by starting the engine and observing fan activation.

5. Clean Radiator and Hoses

• Sub-steps:
  1. Remove any debris from the radiator fins using a soft brush or compressed air.
  2. Inspect hoses for clogs or damage; replace if necessary.
  3. Reattach all hoses securely.
