Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent any electrical shorts.

2. Coolant Level and System Inspection

Check the coolant level in the reservoir and top it off if necessary with the recommended coolant type (e.g., Toyota Super Long Life Coolant).
Inspect hoses for cracks or leaks; replace any damaged hoses.

3. Thermostat Replacement

Locate the thermostat housing and remove the bolts using a socket set.
Carefully remove the thermostat and inspect it for proper operation.
Install the new thermostat, ensuring it is oriented correctly, and torque the bolts to the manufacturer's specifications.

4. Water Pump Replacement (if necessary)

Drain the coolant from the radiator.
Disconnect the hoses from the water pump and remove the mounting bolts.
Install the new water pump, ensuring all gaskets and seals are in place, and torque the bolts to specification.
Reconnect the hoses securely.

5. Radiator Fan Check

Inspect the radiator fan for any obstructions or damage.
If faulty, replace the radiator fan and confirm it operates correctly when the engine reaches normal operating temperature.

6. Refill and Bleed Cooling System

Refill the cooling system with the appropriate coolant.
Start the engine and allow it to reach operating temperature while monitoring the coolant level.
Bleed the system of any air pockets by using the bleed valve, if equipped.
