1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool to avoid burns.
Disconnect the battery to prevent electrical shorts during repairs.

2. Drain and Replace Coolant

Sub-steps:
1. Place a drain pan under the radiator.
2. Open the radiator drain valve and allow coolant to drain completely.
3. Close the drain valve once empty.
4. Refill with the correct type of coolant (Toyota Genuine Long Life Coolant or equivalent) mixed to the proper ratio.

3. Inspect and Replace Thermostat

Sub-steps:
1. Remove the thermostat housing by loosening the bolts (torque specifications: 10-15 ft-lbs).
2. Remove the old thermostat and replace with a new one, ensuring the correct orientation.
3. Reattach the housing with a new gasket or sealant as necessary.

4. Repair or Replace Water Pump

Sub-steps:
1. Remove any components obstructing access to the water pump (e.g., serpentine belt).
2. Unbolt the water pump from the engine block and remove it.
3. Clean the mounting surface and install the new water pump.
4. Reattach the serpentine belt and any other components removed.

5. Test Radiator Fan Operation

Sub-steps:
