Solution

1. Preparation

Tools Required: None specific for checking levels.
Ensure the engine is completely cool before proceeding to avoid burns.

2. Inspect Coolant Reservoir

Open the coolant reservoir cap slowly to release any built-up pressure, taking care to avoid spills.
Visually inspect the coolant level against the minimum and maximum lines on the reservoir.

3. Add Coolant if Necessary

If the coolant level is low:
- Tools Required: Funnel, appropriate coolant (Toyota-approved type).
- Remove the reservoir cap completely.
- Using a funnel, add the correct type of coolant until it reaches the maximum line.
- Replace the reservoir cap securely.

4. Check for Leaks

Inspect hoses connected to the reservoir for any signs of wear or leaks.
Check the radiator and its connections for any visible coolant leakage.
If leaks are found, repair or replace the affected components.
