Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to avoid any electrical hazards.

2. Coolant Level Check

Open the hood and locate the coolant reservoir.
Remove the cap carefully to avoid pressure release.
If low, add the appropriate type of coolant (Toyota Long Life Coolant) until it reaches the full mark.

3. Inspect Radiator and Hoses

Visually check the radiator for any signs of leaks or corrosion.
Inspect all hoses connected to the radiator and engine for cracks or wear.
Replace any damaged hoses with OEM parts.

4. Test Cooling Fans

Reconnect the battery.
Start the engine and turn on the air conditioning.
Observe the cooling fans; ensure they engage properly when the engine reaches operating temperature.
If fans do not operate, test the fan relay and replace as necessary.

5. Flush and Replace Coolant

If the coolant is dirty or contaminated, perform a coolant flush:
- Drain the old coolant by removing the radiator drain plug.
- Flush the system with distilled water until it runs clear.
- Refill with fresh Toyota Long Life Coolant, ensuring the correct 50/50 mix with distilled water.

6. Inspect Thermostat

If overheating persists, the thermostat may be stuck closed:
- Remove the thermostat housing.
- Inspect the thermostat for any signs of damage or failure.
- Replace with a new thermostat if necessary, ensuring correct orientation during installation.
