1. CHECK ENGINE COOLANT LEVEL AT RADIATOR RESERVOIR
The engine coolant level should be between the "LOW" and "FULL" lines at normal temperature (20°C (68°F)).
If low, check for leaks and add "Toyota Long Life Coolant" or equivalent up to the "FULL" line.
2. CHECK ENGINE COOLANT QUALITY
a. Remove the radiator cap from the reservoir.

and steam can be blown out under pressure.

oil. If excessively dirty, clean the coolant passages and replace the coolant.
c. Reinstall the radiator cap.
