Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative terminal of the battery.

2. Replenish Coolant

If the coolant level is low, add the appropriate type of coolant to the reservoir and radiator.
Use a 50/50 mix of Toyota long-life coolant and distilled water if necessary.

3. Replace Thermostat (if faulty)

Tools Required: Socket set, gasket scraper, torque wrench.
Drain the engine coolant from the radiator.
Remove the thermostat housing by unscrewing the bolts.
Take out the old thermostat and clean the mating surfaces.
Install the new thermostat with the correct orientation (spring side towards the engine).
Reinstall the thermostat housing and torque to manufacturer specifications.

4. Fix Leaks

Inspect all hoses and connections. Replace any damaged hoses or clamps.
If the water pump is leaking, remove the serpentine belt, unbolt the water pump, and install a new pump with a new gasket.

5. Test Cooling System

Refill the cooling system with the correct coolant mixture.
Start the engine and allow it to reach operating temperature while monitoring the temperature gauge.
Check for any leaks and ensure the radiator fan engages as needed.
