Coolant: Testing and Inspection
Engine Coolant Protection Inspection
ENGINE COOLANT PROTECTION INSPECTION [MZI-3.7]
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.
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 in the figure.
-
If the engine coolant protection level is not correct, add water or engine coolant.
