INSPECTION
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
The engine coolant level should be between the ºLOWº and ºFULLº lines, when the engine is cold.
If low, check for leaks and add ºToyota Long Life Coolantº or equivalent up to the ºFULLº line.
2. CHECK ENGINE COOLANT QUALITY
There should not be any excessive deposits of rust or scale around the radiator cap or radiator filler hole,
and the coolant should be free from oil.
If excessively dirty, replace the coolant.
