Coolant: Testing and Inspection
1. Check engine coolant level at reservoir tank. The coolant level should be between the "LOW" and "FULL" lines, when the engine is cold. If low,
check for leaks and add coolant up to the "FULL" line.
2. Check engine coolant quality. There should not be any excessive deposits of rust or scales around the radiator cap or radiator filler hole, and the
coolant should be free from oil. If excessively dirty, replace the coolant.
