Engine Coolant Protection Inspection

ENGINE COOLANT PROTECTION INSPECTION [LF]

1. Measure the engine coolant temperature and specific gravity using a thermometer and a hydrometer.

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

NOTE:
- If the "FL22" mark is shown on or near the cooling system cap, use FL22 type engine coolant.
- FL22 type engine coolant is shipped as a diluted solution. Use the solution as is when replacing coolant.






2. Determine the engine coolant protection level by referring to the graph shown.






- If the engine coolant protection level is not correct, add water or engine coolant.
