Engine Coolant Protection Inspection [LF]

ENGINE COOLANT PROTECTION INSPECTION [LF]

1. Measure the 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.

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 (55% coolant, 45% water). Use the solution as is when replacing coolant.

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