Engine Coolant Protection Inspection

ENGINE COOLANT PROTECTION INSPECTION [L3 WITH TC]
1. Measure the engine coolant temperature and specific gravity using a thermometer and a hydrometer.

Caution:
^ Use engine coolant at a concentration that meets the environmental conditions in which the vehicle is driven, otherwise engine damage could occur.
^ The engine has aluminum parts and must be protected by an ethylene-glycol-based coolant to prevent corrosion and freezing.
^ Do not use coolants containing Alcohol, Methanol, Borate or Silicate. These coolants could damage the cooling system.
^ Use only soft (demineralized) water in the coolant mixture. Water that contains minerals will cut down on the coolant's effectiveness.
^ Engine coolant damages paint. If engine coolant does get on a painted surface, rinse it off quickly.





2. Determine the engine coolant protection level by referring to the graph shown in the figure.
^ If the engine coolant protection level is not correct, add water or engine coolant.
